<p>I understand that the Alpha 7 will crop the edges of the frame when APS-C E-mount lenses are used, to compensate for the smaller coverage, and will thus output images of lower resolution.<br>
I'm interested to know whether that's quantifiable: whether it's a fixed crop to an APS-C sized sensor size, or if it varies between different APS-C lenses, and what size the output resolution would be for the 24 and 36 mp sensors in each case.<br>
Is it simply proportional to the ratio of the areas of the FF and APS-C size sensors or is it more complicated than that?</p>
