DxOMark just tested the Canon EOS 70D, and it didn't score all that well. I don't really care myself. Vision is what is important in photography, and not cameras. Besides, there is only so much value in DxOMark tests, anyway. But Canon did call this camera a "game changer" with its new and improved auto-focus.
Yes, the auto-focus may indeed be better, but Canon seems to be falling behind Nikon, Sony, Fuji and others when it comes to raw image quality from the sensor. So what good is improved auto-focus on an overpriced, underwhelming camera?
Again, I don't care myself. I won't be buying the camera. But if I were in the market for a new DSLR (which I'm not) and I was considering the 70D, I would take a good long look at the competition because there is really little to attract me to this new camera. And that can't be good for Canon, who is pushing this as a game changing DSLR.
