FWIW, the last older lens I used that had mucho nasty purple fringing was the smck 200/2.5 which is an otherwise nice lens. I sold it and am afraid to try another one. Older lenses can be great but I tend to dislike older zooms and long telephotos. Modern wins there. The early zooms/long teles were not very good compared to the shorter primes of the same era.
I tend to eschew zooms in general, though I made an exception for the rather porcine but very good DA*60-250. Any of the older zooms I tried were bad lenses with very few exceptions (I have a Tokina 80-200 from the 1980s that is a decent enough lens). Purple fringing, chromatic aberrations and pincushion or barrel distortions, are some of the things that can be dealt with very easily during raw conversion, so if a lens is nice otherwise, it makes sense to keep using it, and use the digital tools available to clean up any optical issues that crop up from time to time.
Modern lenses can still be made to show optical problems. -- William Robb -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
