Third Party Manufacturers / Re: Still waiting for high MP canon while Nikon is coming out with new 800« on: June 11, 2014, 11:05:33 AM »
Try putting decent lenses like a 24-70/2.8L II, a 135/2L, or a Sigma 35/1.4A on a 70D, then shooting moving subjects indoors in a gymnasium, theater, or even typical living room. You'll likely be at ISO 3200 or higher...and the resulting image quality will be nowhere even close to 'on par' with the same lenses on a FF camera.
Wrong, because you are using the characteristics of the sensors in order to draw a conclusion about the size of the sensors. Question: would your comparison still hold true if Canon placed a cropped version of the 1DX sensor in the (eventually) upcoming 7DII camera; or the inverse, if Canon placed an upscaled version of the 70D sensor into a (hypothetical) 1DXs camera?
