Hello,

I was testing my Sony 55mm comparing it to a Sony 24-105 on an A7R4. Everything says the 55mm should be sharper but it is not. I have run several tests at different depths/distances using auto focus and manual focus but the results are always the same. I was thinking of sending it in for a repair but to be honest, I am not certain it was ever sharp. It was my first lens and I did not know enough about photography and equipment to think about these things.

My question is can a lens be repaired for sharpness.

Thank you,

Michael

If lack of sharpness is because of the design of the lens, no. If lack of sharpness is due to improper construction, yes, sometimes.

Maybe you could post some images. The 24-105mm is a surprisingly good lens and used by a lot of Sony shooters. I have both the 24-70 GM and the 24-105. I had done some testes a year or so ago and it was hard to tell them apart.

Vignetting is quite different between those lenses. If you turn off the raw developer vignetting correction you’ll see what I mean.

Me, for one. I like it a lot and my copy (at least) is very sharp.
