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.

me wants full frame! or bigger!

Zach Ashcraft's picture

buy a 5d mark 2...

already have one ;-).. starting to shoot with 6x12 format 120 film ;-) down with digital!

I've recently been in the process of scanning all of my 6x7
Kodachrome and Ektachrome,...and it's just beautiful !

what are you shooting with? ya just cant beat film.. its the old new school...

why are your braging so much. go do your film stuff.

what are you guys using to scan? I'm finding these cheap scanners online and they just kinda suck. I'd love to scan all my negatives. thanks!

Do you have a camera that has more than 18 mpx? do you have access to a macro lens?

You should be able to figure out the rest of the riddle!

ALOT cheaper than buying a cheap scanner, but not as good as the real deal either...

Liking the AF improvements. What about headphone jack?

Yes please!!!

If this is the 70D... I cannot wait for the 7D Mark II
I know specs aren't everything, but I am a megapixel lover, I shoot in daylight so night/ISO Performance isn't a huge deal for me. But the 7D Mark II no matter what will out-do any Crop-Sensored DSLR out there. The Mark II will most definitely blow every APS-C DSLR out off the water.
P.S - I praise Canon for finally moving forward! New sensor, more MP, more FPS... They're actually... WORKING!

that will be a big challenge, nikon(sony) and sony are in advantage with the sensors. But i hope Canon will be a competitor again when it goes to sensors.

Jackson Henney's picture

Oh I don't think they will disappoint. They didn't for the 5D Mark III, and the 7D is a huge cash flow for them. Not that I will be getting it, I will be going for a 5D in my next purchase since I am still on my first camera, a 500D, but the 7D is still an amazing camera.
I do agree though, Sensor technology goes to Sony. They are lightyears ahead, itll be hard for Canon to beat - if they can match it then they will make lots of photographers happy :)

The Mark III sensor is not really all that great, certainly an improvement over the Mark II, but the 6D actually has a better sensor than the Mark III. The rest of it is crippleware of course, but it does have a better sensor.

as if you would see a difference you moron.
all this idiot pixelpeeper and internet noobs.. annoying
go print your stuff you won´t see any difference printing a2 or a1.
not even form a medium format digital back with 50mp.

A bit of sand in our lady part, have we...?

Spy Black's picture

I see you shoot with a D30...

agree. 6d has better latitude, crisper image

If you like megapixels then wouldn't you prefer them to split the diodes to give twice the MP on the sensor rather than waste them on AF? In fact, why are they not doing that? Something doesn't add up here, and it feels like its this: 'only a number of the diodes have the split sensor, and its not that many because they are not trumpeting that number'.

Jackson Henney's picture

I would indeed! If I was given the option to split it for AF or Megapixel count, I would always choose the MP Count. As I said I'm not gonna get the 70D, I think its interesting how they did things and all, I am just excited they finally have a new sensor with more than 18mp.

I have the 500D, and 15mp for me is plenty, but I always crave more. I love detail, being able to crop in more and all those things you just can't get from a sensor which is optimized for low-light performance.

7D is crop sensor APS-C. 7D MK2 will be also.

Spy Black's picture

You have to wonder why they're introducing this technology in a crop frame body.

Is it me, or are battery packs comical?...

Maybe people are willing to pay for it? ...or maybe Canon are using this as a sandbox, so they can later/soon put these features in their (already) feature-packed full frame cameras, without the risk of blundering in the pro- segment.

John White's picture

Battery packs are essential to video. Having shot both photo and video I can definitely say I go through batteries at least 10x faster with video running rather then I can make one battery last an entire wedding with photo.

Maybe because they need a sensor with exceptionally fast AF to gain ground with the upcoming next EOS-M?

This sensor cries to be put into a mirrorless camera.

I use a battery pack on my 60D. Without it, my battery life lasts 3/4ths to one full day, but I swear with the battery pack, I can use it for days without having to recharge. It helps.

Adam Cross's picture

not comical when they're extremely useful and allow for easy vertical shooting - not to mention they make a camera a lot more comfortable to hold, my 5DII is ok without the battery grip but it feels unstable with a medium/large lens on it with and a speedlight in the hotshoe, with the battery grip it all feels a lot safer in my hands - cameras are not made for people with medium to large hands, battery grips make everything better =D

They're obviously prepping for the EOS-M version 2. Otherwise they totally would have done it on full frame instead...

I bet they'll hammer down the firmware after a bit of having the 70D out and getting feedback via reviews then they'll push the EOS-M v2 out as a really appealing option for mirrorless along with a few nice new lenses.

So If each photodiode can capture light independently HDR should be as simple as capturing one frame, first photodiode with lest say iso 100 and second one with iso 800. Using simple algorithm and combining those images should give nice results (similar to ML video HDR) but with no hassle :)

They should upgrade 5DIII ;E

i have a 1D X but i wait for the 7D Mk2 as backup body.
can´t wait to see what they have in mind for the 7D MK2. :)
