Nice test for sharpness/smearing, at that distance. It is a bit hard to judge vignetting on the crops though, since the exposure wasn't kept constant. Looks like a good lens.

Thanks..... my purpose is to show smearing problem in extreme corners.
I will leave Vignetting to infinity distance, and try to keep everything constant as much as possible.
Also, I am going to conduct the test comparing directly with M240 soon (I hope)

if anyone has an idea(s) according to the test, please let me know!!!
I flat scene and no refocusing when shooting the corners would be a good idea for showing possible curvature of field. Just make sure you point the camera dead perpendicularly to the surface, which can be a bit tough.
Aaaand... If possible use the same frames for all apertures, but refocus (edit: on the center) stopped down to shooting aperture. That will get rid of any focus shift issues.
Edit: I think you chose a very good distance for the FLE test. Not too close up, but far away enough to make sense for those mostly shooting landscapes.

This is absolutely crazy. Every test shows different things. I've never seen this kind of mess.
Maybe it's really the adapters? What else?
What part of "images only" is not clear to you? I have repeatedly begged you by PM to respect this. I found this test for you. Please respect the thread guidelines, delete your post, and I will delete this post also.

Look, there are rules for the forum, and then there are threads, but there is no user-owned aspect of the rules for threads. You can request that people don't post comments, but they don't need to follow your request. No need to get unpleasant about it.
Personally I think that threads like this are useless without comments.
