crashpc said:Exactly! OMG we have that 18Mpx sensor in lowest model. Does Canon want to pretend that two more megapixels and some AF upgrades and circuity for these is normal after 5 or more like nearly 8 years of that sensor tech birth?, DOH....

That's actually not true, and I'm pretty sure you know that. You need multiple DPAF pixels to be able to properly detect a phase differential, just like the strips in a dedicated PDAF sensor are made up of multiple pixels in strait or diagonal lines.
You don't actually have 16 million AF points.

MichaelHodges said:In good light the 7D is a good performer. However, once you used the AF of the 5D3 or the 1Dx, you see the differences over there.
It's not just the AF. It's also the sensor.
I agree, wildlife asks for pictures early and late on the day, so light conditions are not that good. So the wildlife camera to beat is the 1Dx, however now with the better 70D sensor inside, a 7D2 might do it well but can't reach of course the 1Dx at lower light conditions.And, IMHO, a camera that only works well in "good light" is not a wildlife camera.

You don't actually have 16 million AF points. No one (outside of Canon anyway) really knows exactly how DPAF works...for all we know, that 80% of the sensor might simply act as one giant line sensor.
jrista said:Based on reviews about the Cinema EOS line after they were upgraded with DPAF, that is exactly how it's described, as "A" focus point...not "many" focus points. The C300 reviews also indicated that the DPAF focus point only really works properly when the subjects are largely centered in the frame...in the periphery, it doesn't work as well. One review also recommended switching to manual focus after acquiring the initial subject lock...so, there certainly seems room to grow for DPAF.

I shoot wildlife/sports/action photography. I use a T2i right now when I'm shooting with a crop. Know why? My glass is all Canon. If it wasn't for that I'd have switched. The 70D offers absolutely no improvement in image quality over the T2i. It's the same flippin sensor, just using new technologies to squeeze a .001% image quality improvement out of it. Now this is coming out with the SAME F'ING SENSOR. The sensor is about 80% of the reason you'd buy a camera, once you choose your subject matter. The 7Dii is going to be a glorified T2i. Same old ancient sensor technology, with a few useless bells & whistles, none of which get down to the root: THEY HAVEN'T MADE A SINGLE INNOVATION IN SENSOR TECHNOLOGY IN YEARS. It's the same mediocre sensor, just rehashed. This is why they're starting to, or will continue to lose market share to other companies. Absolutely insane that it took a half decade to refresh, and it's basically going to be the exact same camera with the exact same sensor, just with a tiiiiny bit extra squeezed out of that sensor. Absolute garbage. I can't tell you how pissed off I am right now.

I hear you, I do. But let me understand the train of thought:
T2i = 18 MP sensor
70D = 20.2 MP sensor (absolutely not the same sensor)
However, at least for noise, I do agree there isn't much difference between the two:
http://www.the-digital-picture.com/Comparisons/Canon-EOS-Rebel-T2i-550D-Digital-SLR-Camera.aspx
But that's the T2i vs. the 70D. Just because the new 7D2 sensor is 20.2 MP doesn't mean that it's the same one.
Again, we don't know the low light performance of this new sensor. Unless we have confirmation from an interview with a Chuck Westfall that it is in fact the same (not gonna happen) or a teardown that it's the same component (and I'm sure there's more to it than just the sensor itself), we don't know what we're dealing with here. Sensor performance is not something a spec sheet will tell us. So we have to let the Bryan Carnathans of the world shoot the samples with the 7D2 (like the ones I linked) and then we'll know for sure.
But yeah, if I was in the market for a new APS-C body, the name 7D2 alone isn't enough to get my money -- especially based on Canon's APS-C sensor track record. I would want to see reviews, specifically noise information.

Another fairly minimal iteration of a mirrorslapper. So little progress after 5 years. Not even WiFi built in. :![]()
How much $$$ did you put into Canon lenses? If you think Canon is "Absolute garbage", then why not switch to another brand?AccipiterQ said:Posted this in another thread, sums up how I feel:

You call that "Another fairly minimal iteration of a mirrorslapper" ?
I wonder what kinda camera you shooting with?

I should have clarified, my biggest beef is with noise. I can be standing next to someone shooting a Nikon and they're at IS01600, meanwhile I'm at 200 because even 400 starts to show way too much noise. I'm thinking it's the same sensor (at least tech wise) since it's the EXACT same mp amount. VERY fishy. I guess we'll see
jocau said:I actually don't really care anymore, because lately I've been looking at the mirrorless options from Fuji (X-T1) and Sony (A7). But I'm expecting the same, rather poor dynamic range at low ISO for the 7DII which we, Canon users, all know too well.

Yawn. If this is an action camera, as most suggest, then low-ISO DR is way down the list of what's important. Landscape photographers should look elsewhere.
