PhotoZone just loves the E50mm on the Nex-7. I guess 4/5 stars is as good as it gets...
Well, with an optical quality of two and a half stars I'm not convinced. If the images are soft near the borders then that's what you see on the screen or on a print, not the value or the build quality or anything else for that matter. Update:
The casual reader may think I'm just having a pop at Sony and while in a way I suppose I am it's because I feel incredibly frustrated. The NEX-7 was right at the top of my shopping list, pending any announcements by Canon or Leica, as a replacement for my now sold Canon 5D Mark II until I realised very late in the day that there is this corner softness issue. It seems as though Sony just failed to go the extra nine yards and add an offset microlens structure, a lesson that Leica learnt and implemented on the M9. Why I don't know but given the "semi-pro" pricing of the body I don't think that decision, if indeed that is the issue, is acceptable. Roll on the NEX-7N.
Gordon's 5D Mark III review includes some NEX-7 imagery taken with the Carl Zeiss 24mm f1.8 lens which you can see here
. The NEX-7 holds up very well in the corner with the mountain peaks so maybe the issue isn't entirely a sensor one and the non-Zeiss lenses really aren't good enough!
It will be interesting to see the results should PhotoZone get hold of one of these lenses for test on the NEX-7.
