Canon Announces the New EOS 70D Equipped with a Dual Pixel Sensor

Canon Announces the New EOS 70D Equipped with a Dual Pixel Sensor

In recent months Fstoppers has shied away from churning the rumor mill, but you no doubt have read about the expected announcement of the new Canon 70D from other blogs. We've been eagerly waiting for its announcement because of what we understand to be a totally new sensor housed within the successor to the 60D: the Dual Pixel CMOS. Canon's newly announced 70D comes with this sensor, which focuses more accurately and faster when shooting video.

canon 70d information

Information is still coming in, but this is what we know so far:
    20.2MP APS-C CMOS Sensor
    DIGIC 5+ Image Processor
    Dual Pixel CMOS AF with Live View
    3.0 inch 1,040k-Dot Vari-Angle Touchscreen
    Full HD 1080p Video with Move Servo AF
    Built-In Wireless Connectivity
    19-Point All Cross-Type AF System
    Continuous Shooting Rate Up to 7 fps
    ISO 100-12800 (Expandable to ISO 25600, 6400 ISO for video

All this is packed in a body that's shaped just slightly differently than the 60D, but comes in weighing basically the same.





"Canon's newly-developed Dual Pixel CMOS AF is an innovative new image-plane phase-detection AF technology that employs a CMOS sensor on which all of the effective pixels are able to perform both imaging and phase-detection AF simultaneously. Each individual pixel (the smallest structural unit capable of outputting an image signal) on the CMOS sensor incorporates two independent photodiodes (elements that transform light into electrical signals) which output signals that can be used for both imaging and the phase-detection AF. When using the EOS 70D Digital SLR camera's Live View function, the technology enables autofocusing with ease, flexibility, speed and accuracy similar to shooting through the viewfinder, enabling sharp focus to be obtained across a wide shooting area1 through phase-detection AF2 until final focus is achieved. Compared with earlier generations of Canon's image-plane phase-detection AF3, Dual Pixel CMOS AF realizes shorter focusing times, outstanding tracking performance and smoother autofocusing during video shooting. And, because Live View shooting can be used in a manner similar to using the camera's viewfinder, the fast and smooth AF performance allows users to concentrate more attention on the subject and composing the photo when shooting."




Phase-detection AF
With conventional phase-detection AF, the light that enters through the photographic lens is divided into two images. The difference in the focus point position between the two images is measured on a dedicated AF sensor rather than the image sensor itself, enabling the camera to determine the direction and amount of lens adjustment required to obtain proper focus. Because phase-detection AF enables fast focusing performance compared with contrast-detection AF, the technology is widely employed in digital SLR cameras, mainly for viewfinder shooting.

Dual Pixel CMOS AF employs the same measurement principle as a dedicated AF sensor, except that it is carried out directly with the image sensor. Its large coverage area enables smooth and reliable image-plane phase-detection AF for both still images and video with no reliance on dedicated AF sensors or contrast-detection AF.

Contrast AF
Contrast AF is an autofocus method employed in compact digital cameras and video camcorders, as well as conventional digital SLR cameras for Live View shooting. Because contrast is highest when an image is in proper focus, the camera analyzes the contrast information from the image on the image sensor, adjusting the lens until the maximum contrast value is reached. While contrast AF offers high focusing accuracy, it tends to require more time compared with phase-detection AF because the focusing components of the lens must be driven during AF measurement to find the point of peak contrast.

Hybrid CMOS AF and Hybrid CMOS AF II
Hybrid CMOS AF is an AF method employed in the EOS Rebel T5i Digital SLR camera and the EOS M digital camera that delivers enhanced focusing speed during Live View shooting and when shooting video. Combining fast phase-detection AF and high-accuracy contrast AF, Hybrid CMOS AF makes possible faster focusing performance than contrast AF alone, quickly measuring the subject distance using a dedicated phase-detection AF image element embedded in the CMOS image sensor and completing the process with extreme accuracy using contrast AF. The EOS Rebel SL1 camera features Hybrid CMOS AF II, which makes use of an imaging sensor that supports AF across a wide area spanning approximately 80 percent of the shooting area measured vertically and horizontally.

So when can you get it and what will it cost you? The EOS 70D Digital SLR camera is scheduled to be available in September 2013 for an estimated retail price of $1199.00 for the body alone and $1349.00 bundled with an EF-S 18-55mm f/3.5-5.6 IS STM lens or $1549.00 bundled with the EF-S 18-135mm f/3.5-5.6 IS STM lens. Also available will be a new Battery Grip BG-E14 that conveniently accepts up to two LP-E6 battery packs or a set of six AA batteries for an estimated retail price of $270.00.

Well I am glad I snagged a 60D 7 months ago as my next camera body. I was thinking about just waiting it out for the 70D but with these minimal spec bumps and price of 1199 for body only I am glad I snagged an older camera that does just as well for sooo much less

Yeah, I can't decide if making an upgrade from a 60D to a 70D would be worth it. Maybe I can hold out for 7D mk2 for a little longer.

When I was looking 8 months ago there were rumors of both a 70D and the 7D ii "just around the corner". I was back and forth on both of those mythical cameras, and they werent even out yet! I was tired of waiting and I snagged the 60D which has been a fantastic camera for what I am using it for. I thought ahead and said to myself that since the 6D is out I could get that as a primary camera and still use the 60D as a very capable backup. If I were you I would snag a 6D now and use the 60 as a backup. Waiting is dumb as the 7D ii has been rumored for 2 years and still nothing. Who knows if it will be another 2 years. Thats my opinion though and you can take it or leave it but I know that I snagged up what I knew would work best that was released at the time and am VERY happy seeing that the 70D was just a small upgrade with things I dont see needed in a next level camera from the 60. Chances are the 7Dii will be for sports shooters and the price will be quite large compared to this 70D. The 6D is a beautfiul camera and for the price its a crazy good deal! So if it was me I would go 6D now and stop waiting, no hope in choosing a camera that isnt out when there are perfectly capable machines out now to choose from.

Also only reason I bring you towards the 6D instead of a new/old 5Dii is that its got wifi and GPS along with a few internal differences. Then the fact that you are using a 60D and I have heard the change from the 60D and the 6D are fairly easy compared to jumping into a 5Diii or a 1Dx or something of that nature.

Oh yeah. If I go full frame, it's going to be the 6D. I got my hands on one and I love the look, feel, and the quality/performance. Everywhere I read says the 6D trumps mk2 and even compares to the mk3 in quality/performance.

For sure, I have a buddy that has one and he said he loves it! He upgraded from the 60D as well and said the transition was just flawless. Not sure what the price differences are on the mark ii and the 6D but I have a feeling the bumps in features and range would be greatly different from eachother (point to the 6D of course). That and I have heard there are just so many different quirky issues with the mark ii that most of my friends didnt like.

"minimal spec bumps" ..... I guess that new sensor doesn't do anything for you? Digic 5? no? ok then. That tired old 18mp sensor in the 60D is way passed it's sell-by date. I would be kicking myself if I bought the 60D only to have the 70D come out months later. The 70D is the true successor to the 50D, 60D was such a step back that only the 7D was a worthy upgrade until now.

I am assuming you are one of those that idolizes over the specs and the megapixel count of a camera? So no the new sensor does nothing for me. The 60D is still a VERY capable camera and when compared side by side I guarantee these two cameras would be so close to comparison it wouldn't even matter in 95% of cases its used. I will gladly stand by my word in saying that the 70D is (outside the video capabilities) just a feature heavy update from the 60D. I also stated in my first post above this one that I am a photographer and NOT a videographer so what I will be doing with this camera will not have anything to do with the new "dual pixel" sensor that is primarily for helping focus for live view mode in video work. 8 Months is along time to wait and sit on an even older camera that had been used and abused that I was using so yes getting a 60D brand new for $500 with a full warranty was the right move and hell I still think its the right move and will stand by it until they start making real changes to that old sensor model and pull it together with better low light capabilities and beefing it up with dual chips. So $500 vs $1199 is a huge deal at the current market as you want to get the best bang for your buck and also make sure to get what you will use. Sure some of those features are nice but I would rarely use them and it would kill one of the top functions of a camera, battery life! I will have to see some DRAMATIC examples of images being edited to see how well the low light (as I can see the ISO max is still the exact same as the 2.5 year old 60D) and also see how well the range is in colors and tones.

idolizes? not really - specifications are just good to know, and no I'm not really into megapixel counts. But still, everyone knows high MP count doesn't always mean better and is only really important if you're going to print something the size of a building or if you want to create one of those Gigapixel panoramas. - I simply stated about the new sensor in the 70D because it is finally a new APS-C sensor (I didn't mention the MP count), Canon have been riding that old APS-C sensor for a long time, the maximum ISO you talk about doesn't really mean anything when that sensor struggles with noise issues when it goes over ISO800 (I almost never used my old 7D above ISO800 because of noise).

I just think overall, the 70D is a much, much better camera than the 60D (heck, even the 50D is still better), even without the upgraded sensor, without the Digic 5+ processor, without the re-inclusion of AF micro-adjustment from the 50D, without the addition of 7 frame exposure bracketing (3 in the 60D), without the return to a higher FPS continuous shooting like the 50D, without all of that it looks to have the same 19 point all cross-type AF system as the 7D, which is really quite excellent.

Personally, all of these upgrades are worth the extra money, in my personal opinion. If you wanted to save even more money by buying an older camera, and are only interested in the end result instead of camera features, you could've gone for the 550D instead of the 60D

Andrew Griswold's picture

I agree they have been riding that APS-C sensor to DEATH! I was just hoping for much more out of this camera than what it is I think like maybe an entire overhaul to the sensor and something worthy of an 'upgrade'. They are taking the Apple points here and updating small things here and there each upgrade to maximize profit rather than really revolutionizing the camera.

And from my point of view I wasnt about to wait 8 months for something thatw as a rumor when I needed a solid camera now. The 70D is a nice camera but seems I will be skipping it and most likely using this 60 as a backup and eventually grabbing a 6D or maybe a mark iii if I have the money to throw at it.

If someone is looking to upgrade now on a budget I would say the 60D hands down as its a very capable camera for anything you can throw at it. If someone has the money go for the 70D but that is a huge price difference for a few features. Maybe I was just expecting a really large update in this camera. More than it is now.

Correction, does look like the ISO is higher on the 70D but let me know how the side by side shots look past 4000 ISO.

I currently use a 60D and have been dying to upgrade. I was waiting to hear firm facts about the 70D or the 7D mk2. However, I recently got a hold of the 6D and really liked it. Seemed to be a great transition from a 60D. But, now I'm torn haha. Should I hold out for the 70D--or even the 7D mk2--or just go ahead and move on to full frame and swipe up a 6D? I mostly shoot portraits, so I don't NEED the speed, but it is nice to have. Having high iso capabilities (without noticeable noise) would be a huge plus. Any advise would be appreciated. Thanks!

I do shoot video quite often. If that helps!

I've seen some serious issues with moire on the 6D in video. Has made me hesitant to invest in it.

Andrew Griswold's picture

Thats a little disappointing to hear. I remember reading your post about it awhile back with Gizmodos findings on that issue but didnt think much of it. I am not much of a video guy and to be honest has never used it on my 60D since I got it. Thought I like the idea that I have it available if need be. Especially if I plan to spend that type of money on another body I would hope its top notch.

a lot of people see the 6d as a bare bones way of letting you go full frame but the 60d and now 70d may have the better focusing system.

Is the 70D capable of shooting images at 300dpi (or better) like Nikon and Olympus dSLRs and a number of mirrorless cameras? The 60D and 7D are not capable of this and that is the reason I have started dumping my Canon equipment in favor of Nikon and Olympus dSLRs!

300dpi is a spec used for print only (300 dots per inch). It has nothing to do with the sensor. Natively all sensors (Nikon, Canon, Olympus, Sony etc.) will read as 72dpi in Photoshop. To get 300dpi you can either convert while maintaining it's current size using interpolation (some details may be a little fuzzy) or you can shrink it down to get the denser pixel count (the best possible print). How large it ends up being depends on how many megapixels the sensor has. Here's a quick chart that will help with sizes. Hopefully this clarifies things for you.

There is no such thing as DPI in a DIGITAL file..this is b/c DPI stands for Dots Per Inch, and there is no such thing as INCHES until a file has been printed....ANY camera can output a printed photo at 300dpi.....if you have a 6000 x 4000 file (24mp) and you print it at 300dpi, you're looking at a 20" x 13" print.....if you have a 3000 x 2000 file (6mp), and you make a print at 300dpi, you're looking at 10" x 6.5"'s ALWAYS about pixels.

6000 pixels wide, is 6000 pixels wide, only the print size will change from 72dpi to the DPI goes down, the print size goes up.....and as the print size goes up, the DPI goes down....

Then explain why the images show up in post processing as 72 dpi and has to be changed to 300 dpi to send to the printer?

That's just how Adobe camera raw, or photoshop, or whatever program you're using is set doesn't HAVE to be changed to 300dpi...well, if you're doing your own printing, i guess it would, but the fact still remains, that can be changed to WHATEVER you want it to be, in about 2 seconds could change it to 12,000 dpi, and the original amount of pixels that the camera has outputted wont far as i know you cant change the DPI in camera, b/c, like i said, IT DOESN'T only matters once you go to print it.....

The fact that you started unloading all your Canon gear b/c of something you dont understand, well, that sucks, b/c if you had just done some research, you'd realize that 12mp output by canon, is the same as 12mp output by nikon, or olympus....the only difference is when you print.....

if you're sending a print to commercial printer, and you order an 8x10, that IS the size that they will print, no matter if you send them a file with 1000 pixels wide (100dpi) or 3000 pixels wide (300dpi)....the DPI of the file will change to fit the print size......

I inquired and inquired, to Canon and Canon forums, but NEVER got a reply. That is really the main reason I am unloading my Canon equipment.

That's b/c most people are idiots, and are as lost as you on the subject....

do an experiment....send 2 files to walgreens......take the same photo into photoshop, on the first one, go to Image > Image Size...then UN CHECK resample image.....type in 72 dpi in the "resolution" save it out as a new file.....

Now do the same thing to the original file again, only this time type in 300dpi....(with "resample image" still un-checked) save that out as a new file, and send BOTH files to walgreens and print 8x10's or whatever....guaranteed they both look exactly the same....why? b/c they both have the same amount of PIXELS.....

Is it weather sealed?

Pretty cool move on Canon's part. The AF system looks really neat and innovative. But as far as Canon's body designs have come over the years, especially with looking more sleek with every next body in a series; the 70d looks kinda ugly. Especial the "Q" and 'Playback" buttons, they look crappy. Im just being really nit picky though, this is stil an exciting release.

Jaron Schneider's picture

I have to agree, the shape of the buttons is really weird.

John White's picture

Personally kind of sad the Menu button was moved from where it was on the 60D.

Besides Video how much different is the 70D as compared to picture quality of the AE-1, I do not care about frames per second just over all picture quality

Looks intriguing!!!

Great pairing with a 6D for longer reach and video. Looks like it's gonna steal some thunder from the D7100! Here's a rundown:
