next PZ lens test report: Sony E 50mm f/1.8 OSS

There is no proof anything is wrong with the sensor. As I said, if there is a problem, it could just as well be AA filter \on the Nex-7, so A77/65 would still need to be tested.



>2. Can you point us to exactly where imaging resource did MTF50 tests of a lens on NEX-7, which did not show weak border and corner performance?



Check the optics section on IR. The corner performance (with the kit lens) is exactly the same as 5N on IR. The right side is Nex-7

I stand by what what I said: Neither DPR, nor IR noted anything about "corner issue" Nex-7 --- that's a factual statement.

There is a lot of proof, photozone points to it, I gave you two other sources where we can see something is going on.

And if you see "AA-filter" as a totally separate entity from "sensor", that is your very own issue and problem... They are a pair that form the whole sensor. The sensor has an AA-filter, just like the camera has a shutter button and an LCD screen.



The corner performance of that kitlens is so very very bad, that one would not be able to see anything in the corners. Again, where are the MTF50 measurements by dpreview and imaging resource?



I gave you two links where you can see unusually bad corner performance wide open with wide angle lenses from top optics manufacturers. One of the links shows a side by side of NEX7 and NEX 5N. And the difference is huge.



You can add to your factual statement that Top Gear UK did not note anything about "corner issue Nex-7", and you can add CNN and Mercedes GMBH too. That all is facual, they all did not test for any corner issue of any NEX-7. Just like dpreview and imaging resource did not.
