The 20-megapixel resolution is Canon's highest to date for an APS-C sensor, and the sensor design is radically different to anything we've seen before. Each pixel not only measures the intensity of light, but also the direction, with each one made up of two photodiodes facing left and right. This helps the sensor to perform phase-detect autofocus, determining not just whether the image is in focus, but also, if not, by how much. It means the lens can jump straight into focus rather than shuttle back and forth in search of a sharp picture.
Phase-detect autofocus is already available in all modern SLRs when using their viewfinders, but in most cases it's disabled in live view mode. The 70D's ability to perform phase-detect autofocus directly on the sensor makes it much faster than the 60D to focus in live view mode.
We've seen this technique a few times before, most recently on the EOS 700D. However, previous implementations have been limited to a few dedicated phase-detect points dotted across the sensor. What's special about the 70D is that almost every pixel can contribute to phase-detect autofocus. The active area is quoted as 80 per cent of the frame, horizontally and vertically – you can't place the autofocus point right at the edge of the frame.
The new autofocus technology is great news for photographers, but it's potentially even more exciting for videographers. The 70D's video autofocus was the most responsive we've ever seen from a large-sensor camera, adjusting in less than a second when we moved the autofocus point using the touchscreen. There was no sign of focus hunting, and face detection and subject tracking helped us follow moving subjects – although once again, it was a little unreliable.
I LOVE IT...!!!

The upcharge for a QVC purchase on this camera body isn't that bad compared to some other Photography equipment I see on here. Of course, easy pay makes this far more convenient for some folks, like myself.
I upgraded from the T3i (Another QVC purchase#. The reason I purchased this particular body as my upgrade choice was due to some coincidental hands on testing. I was shooting for a local Hookah Lounge with really bad lighting. While I don't mind using my speedlight, it's hard to just snap away with customers all over the place without disrupting them.I had the Canon 50mm 1.4 attached to my T3i, which does great in low light situations. The problem I was having at maximum aperture in real time, was the focus in the low light. It just WASN'T getting the job done. For me. I think maybe 50% of my intended shots focused properly.
Fortunately a new colleague I had been working with had the 70D in his bag. When I started complaining about my focus he handed it over to me and suggested I give it a try.
Bam. 100% accuracy. The zone focus point option was PERFECT in my situation. The Dual Pixel CMOS focus system is superb. I was incredibly impressed. I even swapped it over to single point AF and it still performed 90%+ in very low light at 1.4. I was sold.
That being said about the AF system, the video capabilities put the 70D way ahead of the game as far as DSLR filming goes. We had 4 cameras set up to film a graduation ceremony a month ago, and this body took center stage because the AF system is so fluid and intuitive. The LCD is a touch screen which is awesome, but the touch screen becomes an incredible tool during video. The 70D has a feature called "Movie Servo AF" which continuously tracks and keeps focus on a subject. Simply touch the subject on your LCD screen and the camera will track them, keeping the focus where it needs to be. No studdering. Just a nice smooth continual focus. It still blows me away every time I use it.
The only drawback for me #not enough of a drawback to knock a star off# is the noise levels. I expected some improvement going from the T3i. To an extent there is only in that the versatility of your ISO adjustments are more than doubled #the T3i only gives you exactly 100, 200, 400, 800, 1600, 3200, & 6400#. The 70D gives you ISO 100-12800 #expandable to H: 25600# that allow for much better fine tuning.
Image quality is only slightly better than the T3i, mostly I think because the true resolution is about 10% better with those extra megapixels. Other than that, the color depth and image quality are virtually the same. Not to say that's a bad thing but you get the idea.
One other feature really worth mentioning is the shutter speed. I put this to the test in a little league football scrimmage. The 70D is a DREAM in sports photography. The High-Speed Continuous shooting mode is incredible. It sounds like one of those automatic airsoft guns firing at full speed. It's literally 2x faster than my T3i #1/8000s vs 1/4000s#. Between the AF system, and the High-Speed shooting, capturing that "moment" probably doubles in success rate. I highly recommend you get yourself one of the "Extreme" write speed SD cards #80MB/s+#, otherwise the High-Speed shooting WILL lag as the camera attempts to write the image fast enough to keep up with the super fast shutter #this is especially true when shooting in RAW + JPEG#.
All in all, the 70D has been a worthwhile investment for this semi-pro photographer. I love it. Even without a full frame sensor I get a lot of compliments on my photography. The 70D I TRULY believe has assisted me a great deal in the field. I couldn't recommend this model enough. Especially if DSLR filming is your bread and butter. Though I think we all know the 5D MKIII is the cream of the crop in that respect, but for a 3rd of the price this is worth every penny.
