Hi
no, I meant it differently. Let's assume you only have a Leica 35/1.4 and a 50/1.4.
If you use i.e. the 35/1.4 lens on a NEX7, you would end up in a kind of a similar crop, but a bigger DOF then the same photo made with the 50/1.4 mm lens on the M9. But you do not want to go more "tele" in that situation for other reasons.
Would that not bother you? With APS-C I find the background often too much distracting compared to FF. I have often situations, where I can not choose another background or another distance to the subject.
