Hi folks, I'm seriously consiering building up a everyday & everywhere system with NEX and some M mount lenses. I'm not an expert on RF, but heard some argument that due to the very short flange distance, vignetting can be an serious problem for larger size cmos. It seem M8 and M9 solves this problem by using some sort of offset microlens. Not sure if NEX employ any similar machenism. Or maybe a APS-C cmos together with the sweet spot of FF lenses make corner vignetting a non-issue?
