Since I own a Sony a65 and was looking for a fast lens, I came across the T* Distagon 24mm F2 of Zeiss. I’ve decided to buy a used one in good condition and was happy until I noticed something while testing:

It seems like there is a circle where the optical resolution is much lower than in the rest of the picture (at least I assume it’s a circle because the dunes in the foreground are out of focus, so they’re blurry anyway...). Does someone have an idea what can cause this or have experienced this? The seller assured me that the lens have never been dropped or anything. I was using a UV filter (just as protection), but without this still occurs. The front and back lenses also looked fine. I’m considering having the lens repaired but I’m unsure whether it’s worth it.
