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

If there is a problem (and neither DPR, nor IR noted it), it still might have nothing to do with the sensor. Maybe it's the AA filter. Unless you do side by side tests with A77/A65, you can't blame it on sensor.



Isn't there anyone in Germany that can lend you A77 or A65?

Wow, you are persistent and repetitive.



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



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?



3. Can you explain to me how an AA-filter can cause very high MTF50 results in the center of a sensor, yet quite poor results on the edge of the sensor?



If you can not produce point 1 and point 2, why are you posting this over and over? All I can find on dpreview in the test of the NEX-7 is the mention of visibly soft corners and edges with the 18-55 they used at almost all settings. Nothing at all for the rest concerning any testing of corner resolution with the NEX with either wide lenses or wide open lenses, nothing at all.

Which of course is probably because dpreview actually never tests that, with camera reviews.



As for your selective reading:

Corner performance of NEX 5N vs NEX 7:

Wide open performance is crazy bad on the NEX7, and it is not the lens as on the NEX 5-N is looks great.



Totally backs up what Klaus have come across with two separate NEX-7 cameras.



And here we see crazy bad border results for two top class lenses (one Zeiss 24mm, one Leica 24mm) from wide open to about f4, also on a NEX-7.

Again, totally consistent of what Klaus is finding. I guess according to you it will be the Leica and Zeiss lens that are at fault there? That they just have weak corner/edge performance standard, and that they will not do better on for instance a NEX-5N?

And they are full frame lenses for that matter....
