Whether you’re in the studio, shooting landscapes in the country, or photographing an event, chances are you’ve been looking forward to the highly anticipated EOS 5D Mark IV DSLR Camera. The Mark IV offers a slew of upgrades, including a 30.4MP full-frame CMOS sensor and DIGIC 6+ image processor that work in tandem to enable DCI 4K video recording, a native sensitivity range of ISO 100-32000 that can be expanded to ISO 50-102400, and continuous shooting up to 7 fps. Alongside the Mark IV, Canon is introducing two updated L-series lenses, the EF 24-105mm f/4 IS II USM Lens and the EF 16-35mm f/2.8L III USM Lens, as well as the SD memory card-sized W-E1 Wi-Fi Adapter for the 7D Mark II, 5DS, and 5DS R.
A multimedia maestro: the 5D Mark IV
In addition to the refined sensor, updated processor, and faster continuous shooting, the 5D Mark IV is equipped with a wide native sensitivity range and 4K video-recording capabilities. Other new features introduced to the 5D series for the first time with the Mark IV include a touchscreen for intuitive control over focus; built-in Wi-Fi, NFC, and GPS; and a brand new Dual Pixel RAW function that enables adjustments in post processing.
Focusing has never been faster or more precise as it is with the vertically expanded 61-point autofocus system, which includes 41 cross-type points to benefit still and moving subjects alike. Autofocus is effective across all 61 points at f/8, and the center point is sensitive down to -3 EV. This increased sensitivity benefits focusing speed and accuracy in low-light conditions, and is especially useful when using a teleconverter along with a slower, longer lens. When working in live view for still or video shooting, the Mark IV offers Dual Pixel CMOS AF, which provides responsive and intelligent focus tracking on moving subjects, and allows for smooth focus transitions between one subject to another. It also benefits from even greater sensitivity—down to -4 EV—for working in low-light conditions.
The 150,000-pixel RGB+IR metering sensor is similar to that which resides in the 5DS/5DS R, offering more precise face detection, scene recognition capabilities, and aids in the detection of flickering lights for exceptionally accurate exposure metering. Helping to ensure sharpness is the Mirror Vibration Control System, which works to minimize mechanical vibrations caused by the mirror during your exposure.
The touchscreen monitor offers intuitive control over oft-used shooting and navigational controls, including tapping to select a focus point, racking focus during video capture, or using familiar swipe and pinch movements during image review. Optional deactivation of the touchscreen allows for a more traditional button-based control. Whether or not you take advantage of the touch feature, the 3.2" 1.62m-dot screen provides bright, clear image playback and live view shooting.
Those working in video will rejoice at the inclusion of DCI 4K recording at up to 30p. In addition to the standard frame rates, the Mark IV offers a true 24.00 fps recording option and is NTSC and PAL switchable. The camera records 4K internally using MJPEG compression at a bit rate of 500 Mb per second with 4:2:2 sampling and 8-bit color depth, while Full HD 1080p recording using Canon’s familiar compression options has 4:2:0 color sampling. When shooting 4K, the central 4096 x 2160 area of the sensor is used at a 1.74x crop in order to record 4K video with a 1:1-pixel ratio, effectively eliminating moiré and aliasing. The full frame is utilized for Full HD recording. Slow motion is possible in Full HD 1080p at 60 fps, while HD 720p is available up to 120 fps, though it is recorded without sound. For use of an external monitor or recorder, the Mark IV has a mini HDMI out, which can output a Full HD image using 4:2:2 color sampling.
You can use a 3.5mm jack for connecting an optional external microphone to record audio, or the onboard stereo microphone; a 3.5mm headphone jack can be utilized for real-time monitoring. An added bonus of 4K video recording, the Mark IV allows you to pull an 8.8MP still from your footage. Furthermore, built-in interval shooting is available, which enables time-lapse capture of a subject changing or moving over a long period of time for an unlimited number of shots.
A feature making its debut in the 5D Mark IV is Dual Pixel RAW, allowing you to utilize captured information to make adjustments in Canon’s Digital Photo Professional (DPP) 4.5 software. Micro adjustments can be made to improve apparent sharpness and bokeh quality, as well as reduce the appearance of ghosting for greater clarity. Another new feature of the 5D Mark IV is in-camera Digital Lens Optimizer that can process files to create corrected JPEGs as you shoot.
For the first time in a 5D series camera, built-in Wi-Fi and NFC in the Mark IV allow easy file transfer to a compatible smart device when using the Canon Camera Connect App. Remote control of the camera’s settings can eliminate any camera shake during long exposures and allow for better composed self-portraits. Also a first for a 5D is built-in GPS, which allows you to geo-tag imagery in-camera and offers an automatic time sync.
Physically, the Mark IV has a familiar robust magnesium-alloy build, with improved resistance to dust and water provided by added sealing around key contact points. An Intelligent Viewfinder II uses a pentaprism design and allows for more options and customizations of what is displayed in the optical viewfinder. Controls remain similar to previous models with the addition of a new AF mode selection button providing quick access to focus areas and the Canon N3 remote port’s relocation to the front of the camera for easier access. One SD memory card slot and one CompactFlash memory card slot allow you to extend your file-saving capabilities by permitting overflow recording, in-camera file type separation while shooting, or setting up an automatic backup. The Mark IV comes with an LP-E6N rechargeable lithium-ion battery and accepts the original LP-E6 so you can keep using your existing collection of batteries.
Regardless of which camera you currently have in your arsenal, it’s impossible to be unappreciative of the continued refinement in image and video quality, autofocusing capabilities, speed, and processing in the 5D Mark IV. With the inclusion of 4K video recording, 7 fps in continuous shooting, an improved 61-point autofocus system, Wi-Fi, and a touchscreen, the Mark IV adds a modern multimedia option to the expanding 5D family, where it joins the super-high-resolution and stills-centric 5DS/5DS R and the tried-and-true 5D Mark III.
The 5D Mark IV will be available body only, as a kit with the EF 24-70mm f/4 Lens, as well as a kit with the EF 24-105mm f/4L IS II USM Lens. Also, a new BG-E20 Battery Grip will be offered for those looking for increased shooting time or improved ergonomics in a vertical orientation. This grip is of similar construction to the camera body and also offers a camera-alignment pinhole for use with video-oriented tripod heads and quick-release plates. Another accessory, though not dedicated to any one camera, is the PC-E1 Protecting Cloth, which wraps around the camera to keep it safe.

Updates for a pair of classic L-series lenses
In addition to the 5D Mark IV, Canon also updated two of its most popular L-series zooms: the 24-105mm f/4 and 16-35mm f/2.8. Starting with the EF 24-105mm f/4 II lens, we have an all-new optical design with improvements in peripheral brightness for reduced vignetting. This high-performing wide-to-short telephoto zoom lens features a constant f/4 aperture, an integrated Image Stabilizer that offers up to four stops of shake correction, and a ten-blade circular aperture for smooth bokeh. A new zoom lock switch is also incorporated to prevent zoom creep when walking around or when the lens is not in use.
Another improvement to the Canon lineup is the new EF 16-35mm f/2.8L III USM lens. This L-series ultra-wide-angle zoom lens is perfect for photographing architecture, events, and nearly everything in between and, due to the use of a constant f/2.8 maximum aperture, the lens will perform admirably in low light. A new optical design includes a large-diameter GMo dual-surface aspherical element and a ground aspherical element, allowing for improved sharpness in the corners and edges. The nine-blade circular aperture also produces smoother bokeh.
Both updated lenses feature internal focusing, as well as a ring-type Ultrasonic Motor (USM) for faster and quieter focusing. Also contributing to the improved image quality are the Subwavelength and Air Sphere Coatings, which help reduce flare and ghosting for increased contrast. Improved sealing provides added protection against dust and unwanted drops of water, and a fluorine coating on the front and rear lens surfaces reduces smears and fingerprints, which is useful when out in the field or weaving through a crowded reception. Both lenses also allow for manual focus override while in AF mode, allowing you to quickly make adjustments when needed.

W-E1 Wi-Fi Adapter
Aside from the Mark IV, Canon has also revealed the W-E1 Wi-Fi Adapter for adding Wi-Fi connectivity to the 5DS, 5DS R, or 7D Mark II DSLRs. This adapter is unique in that it is shaped like a standard SD card and is installed by just sliding it into your camera’s card slot. Some of the features include a 32.8' range, easy transfer of images and videos in MP4 format to a compatible smart device, and the ability to use a mobile app for remote camera control. For those looking at getting the 7D Mark II, you will be pleased to know that the camera will now be offered in a kit with the W-E1 Wi-Fi Adapter, or as a kit with the EF-S 18-135mm f/3.5-5.6 IS STM lens and the W-E1 Wi-Fi Adapter, so you can always be connected.
With the announcement of this new camera from Canon, we know we won’t have to ask you to post your thoughts in the Comments section, below. So, have at it.
Most frustrating for me is the loss of the rear curtain (second curtain) shutter. I'm at a total loss why they took this out. I was hoping it would be back in the 5D MKIV. Nope. Still figuring out if Pocketwiz will pull it off, but documentation is thin.
There are many things to like about this camera ... along with one major problem: the RAW files shot with his camera are not compatible with current Mac OS software (other than a new version of Canon Professional). Hopefully this will be corrected soon.
Bring on the 6D Mk2 in Feb, i will wait for that, full frame at a lower price or used 5D Mk3.
In the video, Doug says the 5d4 "inherits" the Digital Lens Optimizer. Where does it inherit it from? As far as I know, it's the first camera with it...
The Digital Lens Optimizer was first introduced in Canon’s Digital Photo Professional software. I believe when Doug mentions the 5D IV inheriting the Digital Lens Optimizer, he is referring to Canon’s editing software.
SInce I use my MK III exclusively for video, with an attached Video Devices PIX-E7 for recording, I was anticipating the Mk IV would be my upgrade camera for DCI 4K. I was shocked to read that the HDMI output is still limited to HD, no 4K. What were the dunderheads at Canon thinking? Why wouldn't they make the 4K accessable on the HDMI O/P?
I guess Canon won't be my upgrade path to 4K for video...
why didnt they ask what we needed first and the price
Meh! Can't say I'm impressed. Kinda like selling a good car but it has a new sound system and the price of the car goes up by 1.5x. NFC, Wifi are nice but not necessary. Memory card speed and newer formats should be supported. 4K video is nice but not necessary since there are a lot of very good 4K videography cameras out there for very reasonable $$ - look at Sony AX with amazing IS. I personally don't see enough of a delta between the mk3 and the mk4 to warrant this price. ISO range is no surprise. Basically it tells me that we've practically reached the end of the road as far as cmos sensors are concerned.
I hope that Canon comes out with an eyecup extender for the 5D IV with its touch screen.
So Canon still haven't linked the spot metering to focus points then. That was in my top three features that I was hoping for. I'm really not sure it's worth the money for the new features it does offer, so I think I'll stick with my mkiii.
Canon discontinued linking the spot meter after EOS 30D, while Nikon offers that feature on most of the bodies.
I saw this feature in the 1DX MK2
Many years ago a supposed wise camera reviewer said that 6MP was all we needed. That anything else was overkill. Despite no one listening to this sage we now approach more than that in cameraphones, 20MP in point and shoots (some there already), with Sony, Nikon, and Canon coming up on 50MP soon. Camera cards continually evolve and mega drives or larger cloud capacities are also becoming the norm, though SSD (desirable for faster viewing through huge picture files) has put a glitch in their market temporarily with higher prices for it's larger drives. Where are we headed and at what point will we abandon digital and move on to the next thing? Is there anything in the works as far as a complete new photo delivery system that surpasses what we currently have besides a possible standard of 4K or higher in straight shooting still format? Other than the LS7 coming soon what else is out there? Let's have CNET do a future article on it if anything.
most interesting for me , personally that 5d classic price, used, will fall to $100 and mark2 to $300 in less, as some people prognoses. so it good way for me to try full frame (I'm in the Lumix area it not FF here((()
I didn't notice but does the video feature still not have auto focusing capability.
Hi Joe -
As with the Canon 7D Mark II, auto-focus is maintained while shooting video. Be sure that "Movie Servo AF" is enabled.
Dear Canon leaders. Good luck and grateful & useful video shootings so nice licking 5D m4,tq regards Sreedhar Rao Donthi General secretary Ap state photo assocation Amaravati,nellore,
Yawn. Confused. Wow. I expected much more. In some ways my 7D Mkii is at least as good or better, now with Wifi/remote. Had high hopes for better video/audio (2ch?, 120fps 1080p?). This might mean that Canon is pushing the video shooter to its XC line? or EOS C line? If I don't move to Sony for video then I will likely buy the EOS-1D X. The difference is not that much and the feature set much richer.
Looks like a really great camera. Love the full sized CMOS sensor and the increased MP. However, with the pending arrival of new and upgraded techonloy for faster and larger storage of files with CFast and/or XQD memory cards, this model should have offered one of these options. Why buy this camera, with 30.4 MP images, which will require additional memory demand, when it will utilize yesterday's CF Card technology. It seems you will have to buy another camera when the faster CFast and/or XQD memory cards arrive this year.
You guys are all missing the biggy here. DCI 4k 500Mbps MJPEG 4:2:2 i-frame recording like the 1DX-2. Not 4:2:0 long GOP high compression MP4 garbage. Not UHD.
Real digital cinema potential for big screen indie filmmakers. Next best thing to raw. Forget high frame rates.
I fully agree!
Not sure if I would say MJPEG is the next best thing to Raw, but 500Mbps and 4:2:2 sounds good.
But 4K video crop of 1.7x crop is a pretty big kick to the gut! And no 4K HDMI out? (T_T)
I used my mk3 primariy for video, and the 1080p was always really soft. Beautiful, but soft. So if the 1080p on the mk4 has a tighter resolution, that would be an upgrade in itself - we'll have to see. Most of the time good 1080p is still plenty.
I'll also take Canon's beautiful colors over LOG as well. ... But maybe there's so much processing going on, there's nothing left for 120fps or hdmi out.
4K DCI cropped 1.74 is a shame but i understand they have to protect the C300 and C500 series. It's quite useless with that crop. Better to use a proper video camera. About MJPEG, 500Mbps seems more than enough.. before you realize that motion jpeg is an highly unefficient old codec (has less banding than H264, perceived sharpness is almost the same) which eats your card in few minutes...
I don't approve the primitive strategy of Canon . It's time for medium format for this price ,not for the full frame .Canon wake up ,it's 2016 . The full frame need to be se democratized on the body's like Rebel series and it's time to change the mode of video record ,on AVCHD not MOV .
C-Log? Dynamic Range?
The 5D IV does not have C-Log. As for dynamic range, this isn’t a specification typically provided by DSLR manufacturers. We will need to wait for the camera to be released and third party testing.
Yawn, thanks Canon will be saving $$$$$ no need to buy.
Will wait for new 6D next year.
Are you sure??
The 6D MkII in 2017??
OMG! Canon is incredible!
I still think it will lose customers. Here it is evident that they do not listen to competition or customers. Locked in a bubble.
I can not stop believing that is 2 or 3 steps behind the competition.
1080 at 60fps? 1 year ago Sony launched the A7Sii with 120fps !!! And Canon can not give more than that?
Now I have many more reasons to to change to the competition, Canon thanks for making it easier to choose my future camera!
They need some guts to do something good.
AHAHAHAHAH omg what a joke. This is a sad day.....gosh what a disapointment for the price. Better get a a7r II seriously.
I agree, i will!!!
I believe that your comparison table entry for the 5DS/5DSr has an error: Focussing support for f/8 is only available at the center and 4 surrounding AF points, not at all points as shown in the table.
Hi Gus! You're absolutely right! Thanks for pointing this out for us - correction has been made!
What an absolute dissapointment. In both features and the price. I'm not a videographer. I use my camera for photographs only. There's just nothing here for me, especially at such a high price. All I want is my 5D MKIII with better dynamic range and improved noise reduction. Why doesn't Canon get it??? (Is Canon trying to force me to switch to Nikon to get what I need?)
To be fair, there's no mention of what the dynamic range or noise reduction will look like on the 5D IV. While this is a bit worrying (particularly the dynamic range being absent from the announcement), it is still possible that the 5D IV will have everything you need in a still camera while still making life easier for photographer / videographers (something the 5D III took a lot of heat for). Personally, I'm cautiously optimistic with the announcement - it addresses a lot of the issues that were aimed at the 5D III including wi-fi, GPS, 30 MP, 4K video, touch screen, etc.
I feel that Canon has been listening and that they've built what will likely be a magnificent camera. Most of the comments I see here are disappointed in the lack of one particular feature or another, but they tend to ignore what Canon has done right.
Anyway, not thrilled about the price, but not surprised either. Now the filed testing on the 5D IV will be the really interesting part to me.
Joel, no doubt many are pleased with the announcement. The lack of Canon proudly touting better dynamic range and noise performance is a glaring omission from this announcement. (This is after all supposed to be a 'camera' and this is kind of an important feature!)
The Wi-Fi and GPS aren't useful for me and how I shoot. These 2 things are just excuses to drain my battery and would be disabled internally if possible.
The 30MP sensor is larger than my 5D MKIII, but considering I can already print high quality 20x30 prints, I'm not sure it's needed, other than maybe on those photos where you have to crop down to your subject.
The video features are of no use to me. I never shoot video and wished the video features didn't even exist in my 5D MKIII. If I was in to video, I'd buy a dedicated video cam with all the bells and whistles that a video fan would want.
I've never been impressed by touch screens. My fat fingers don't work well with them either and a touch screen is just something waiting to break or not function in too cold or too hot conditions in my opinion. (But then I find touch screens on laptops a complete waste too.)
So in the end, all I ever care about in my camera is image quality of still photographs. I'm not a pro and take a simple approach to my hobby. I only ever use a single focus point, normally shoot in Av or Manual mode and don't use 90% of the fancy features built into the 5D MKIII. If the dyanamic range and noise reduction is greatly improved, then this is a camera I could be interested in. (Though the price prevents me from considering it any time soon.)
But usually the trick Canon pulls is to increase the sensor size like they did to 30MP and then claim "Well, the noise is similar to the previous model, but since the sensor is larger, it's better noise performance." I on the other hand feel that is hogwash, when the level of noise in your images is still essentially the same as the previous model, it most definately is not an improvement.
There will be no shortage of reviews over the next several months that will show image quality and performance and I have nothing but time on my hands anyway. If it's better, I could see buying this model one in a year or two, after the price has dropped well below the $3K range.
With the cost, Canon is sticking with that 100 year old business model of not everyone should be a photographer.
We know the new sensor has on-chip A to D conversion like the 1DX mark II. This almost certainly means better dynamic range and less noise in the shadows. Couple that with WiFi, improvided focusing, higher resolution, and improved screen and you have a pretty decent stills upgrade. I wish the pricer were lower too, though.
What about the image quality ? Like before, when they release the 5D Mark III, NOTHING is mentioned...
Looks like is not possible for Canon provide a camera with similar image quality of the competition.
I was waiting for almost 3 years to see if Canon will provide something in the level of the competition, I'll just wait for the relieable reviews...
After that, If this camera do not delivery the quality in the level of the other brands, Is time to shift to the competition.
I absolutely agree with you Keith, improve, improve and improve noise reduction instead adding more features to a camera.
The camera I've been waiting for!
For fotographers not video shooters : isn't it worth spending more 300 $ and get the 5d sr with 50 mp ?
I have owned every 5D including the sr. I also own the 1dx markii - the rs is my least favorite. It is still the prior senso as the 5d markiii. The sr does have great resolution, but it is a dog in low light. Such a dpg, that i actually bought a another 5d markiii after i had just recently sold my old one. I think this mark iv may be a great camera, with good resolution and still good in low light.
I 100% support that response. I was waiting for them to drop this to decide between the two. Fuji is my choice. Sad day canon.
I'll be sticking with my Mark I thanks...
No built-in panoramic mode? We went to Iceland for a photoshoot in Jume and I had my 5DSR and my brother had the Sony Alpha. We shot tons of panoramas but mine were all manual with tons of post-processing while my brother just did all of his in camera. Canon needs to keep up.
Sony is schooling Canon at the moment
Sony's attempt to dominate and to beat Canon results in a overwhelming number of slightly different models as such as the alpha line. You can count on a new model every few months. Canon on the other hand has a much better and much more careful ratio throwing new models on the market. I will definitely buy no Sony as their products aren't thought out completely like Canons are. Panoramic mode? Come on... I guess battery life and avoiding overheating are much more important.
Sony changes/upgrades every year, not every few months. But, can you beat them for the price. The older models go down in price. Look at the 7s or 7r, before 4K.
The rule for me is: Test, Test, Test then compare.
Maybe you are not so, "Thought out completely",
Well ok, let's say I'm not a Sony fan at all having had several products of them over the last two decades. I have never been 100% satisfied with quality overall, may that be because of hardware, software or not to speak about reliability and service issues. I've tested the alpha 7 series and yes, they are in fact nice and powerful, which caused me to give Sony another chance and to buy an alpha 7s II along with an adaptor for my Canon glasses. From the start I fell in love with it until I was badly disappointed when I did a video shooting with actors, staff and clients involved on set. All I can tell you that it is no damn fun having a overheated camera on set and everybody has to wait for the camera to cool down... even with the newest firmware. I will sell it as soon as the new 5D comes out for sale. From this perspective, the price to offer ratio, even if the Canon by all meanings is not cheap, is much better at Canon's side.
Canon has never let me down, not once, which in my opinion is a underestimated value of their ProDSLR's and Camcorders, even if they don't deliver the same specs like Sony and which Sony by the way pushes to their limits, which again scratches on the above mentioned reliability. That said, they are forced to push the boundaries to catch the attention of guys like you and get higher in the market. Maybe Sony works for photographers, but for hybrid users like me who mainly want a clear workflow when doing video any of their actual digital cameras will keep staying away from me.
To answer your comment: Yes, I agree on the testing and comparing part, which I do on a regular basis. And I will be very happy to go along with my new 5DmIV. If its built like its predecessors, especially the 5DmIII, it's going to be a workhorse I can fully rely on. :-)
I LOVE my canons. I have had all of the 5D's - still have a 5DM3 and the 5DSR and they are my primary camera. But it was an ah-ha moment when my brother-in-law who had the new Sony Alpha 7s II was constantly automatically shooting panoramas and I had to do mine all manually and then in post, get them put together. We compared our resulting (Canon vs Sony) panoramas and his were everybit as good, but done with dramatically less effort. I am not suggesting i want to move to Sony as the Canon is like a glove on my hand and I know the controls blindfolded, but I wish they would put a panorma mode in it to make it easier as an option for those of us who are landscape photographers...
Sony is most definitely besting Canon in terms of better technology and better at satisfying customer demands. The only thing Canon is winning is money. But their products, when you compare them to competitors, are almost always lacking and have a higher price tag. Why.
I really doubt the dynamic range and noise levels will compete with past Nikon and Sony models...
Carson, I can't see your purpose of posting this here. If you're not into Canon stick with your Sony, Nikon, Fujifilm or whatever you used to take pictures or videos with. Do not buy a Canon. :-) I'll stick with Canon as I think they're doing it just right. Better technolgy and customer satisfaction on Sony? I really doubt that.
Personally I think the new mIV is a big hit for existing Canon users. The differences from the mIII are huge! Forget the 30MP, for me this is a nice to have. But finally we get real in-camera 4K (not UHD), WiFi, GPS, DualPixel AF and a touch screen for easier adjustments. How many times had I wished for touching a function directly on the screen only with my thumb, rather then fiddling around two-handed with the joystick and the Menu-button...
Many of the posters here claim they need no video function at all. Don't forget, the 5D is and from the mII on has always been designed for photgraphers AND videographers. If you only want to take full frame pictures, go for the 6D or 1D instead.
The price tag is as usual with Canon but I think it's justified by the point where we come to the versatillity of having one camera which can (hopefully) perfectly be used as a photo and a video camera. In this price range and even above there is no pro camcorder out there which uses the same sensor size and despite the 1.73 crop factor in 4K, in Full HD the whole sensor is used to catch the scene, which means beautiful shallow depth of field and a nice bokeh for filming too.
In addition, if the camera really delivers more detail, less noise and a working autofocus while recording video, what do you want more? You also can use your 'old' fast CF cards (I already own five expensive UDMA7 x1050 128GB cards) and the batteries from the mIII. No extra costs here. In short, you get the full package.
You said nothing that refutes one word of Carson's observations. You could have just stated, "I am a Canon freak" and spared us the advert.
