Hallo VM, I agree with your narrative as it stands (although I don't agree that a large sensor gives you less depth of field than a smaller sensor as it's more the focal length that does) but, it reminds me of my more youthful days when I used both medium format and 35 mm cameras and, in those far-off days, it was often said that for quality you couldn't beat a larger negative.

Where I'm coming from is that a FF image needs much less enlarging than an APS-C for e.g. an 8x10 and thus shows less noise (thus higher quality?) at a particular ISO setting.  Also, you're correct that depth of field is less but, unless you frequently need extensive DOF, it often doesn't matter.

I like your comments and they made me think but, as an old available light fanatic, I love my A99 (and thinner DOF on people pics) while still enjoying the reach with zooms on my A65.

Take care.  Tom
