35mm 1.8 on an adapter.
I've decided that most people who talk about the performance of cameras and lenses have never shot with cameras and lenses or, what they've shot are flat, ugly and useless two dimensional test charts. I've been looking a PhotoZone.de's reviews of different lenses on the Nex 7 and they speak as if there is a known sharpness issue with the Sony Nex 7's sensor. According to their numerical results you should be seeing a sharp center surrounded by a sea of optical jello in the image above. But the image above was shot hand held, without the benefit of image stabilization and at a fairly wide aperture. To make matters "worse" it was used near its close focusing limit which, for a lens not blessed with floating elements, should be its worst case scenario. It was even a manually focused lens hanging off the front of an adapter ring. And yet, to my eyes the bowls in the center seem sharp where I've focused on them and the bowls in the bottom left hand corner of the frame seem to be sharp as well.
Could it be that I'm just lucky at picking out specific cameras and fortunate lenses while all the review sites are getting rejects? I doubt it.
It finally dawned on me. I must be doing something wrong. I must have forgotten some esoteric technique that allows me to really see these optical combinations in the eery light of their inadequacy. Oh well, I'll keep testing. Something will come to me.
