Thank you all very much for your comments and help!!! I'll buy the Takumar 28mm instead I think and sell this one or give it to someone. There must be something wrong that I cannot fix. Well it was great learning lesson, I've never dissambled a lens earlier. Everything is centered and locked like they should be. There was one glass that looked the same both sides and yes I tried to put it both ways. Mikkokan wrote: I have now disambled and assembled the lens maybe 8 times.

This defect is less pronounced on the "Made In GDR" copy than the "Multi Coated" one. I own two different copies : the first one is the common Pentacon Auto 29mm f/2.8 Multi Coated and the latter is a one that says "Made in GDR" on the front, has a button to test the DOF (not to be confused with a Manu/Auto switch) and with orange ink for some letters (focus distance if my memory is OK).īoth lenses show the same effect on APS-C and stopping them down does not change things a lot. You can probably find tons of examples on flickr if you look.ĭok wrote: I have already noticed this problem, and I'm with an APS-C camera. If it weren't they wouldn't have sold so many of them for so long. Mos6502 wrote: This lens is normally great on full frame. It looks like this lens is never been disambled earlier, no scratches in srews. Now the right corner is blurrer than left when dissambled the lens and assembled it again. Mikkokan wrote: The rear elements can only be assembled one way. I had the exactly same effect when I had disassembled my Zuiko 50-90mm f/3.5 to clean it and mislpaced one element (turned it upside-down). Here are examples after centering (or at least I tried something )ĭoes anyone have full frame and this lens that could test if this lens is unusable in full frame.ĭsmlogger wrote: There is obviously something wrong with the placement of the glass elements. I also centered the rear element, corners are still blur. ![]() Mikkokan wrote: Opened the lens, everything seems to be ok. SinfulSaint wrote: I use the same lens on my A33 APS-C. But that's just one of several possibilities that could cause the effect shown in your photo. If an element is loose it may be as simple as tightening the retaining ring down. Mikkokan wrote: Thanks! So in theory this can be fixed? Mos6502 wrote: A loose or decentered element.
