The Jupiter lens are quite good. After the 2nd WW russian had access to the Carl Zeiss Jena factory and they copied a lot of CZJ lens. So far I know the 135mm Jupiter is almost just a rebadge of the famous Carl Zeiss Jena Sonnar 135. I don't know about the newly made versions, but one thing is sure: the 30-40 years old russian and east german lens was, are and will be great lens :D Pure glass and metal. No plastics :D
Also the russian and DDR lens are very tough. Today I my Tair 300 (used with the photosniper) fell from approx 1 meters. Normally if it happens with a newer Sigma lens I would be nervous if anything happened with the lens. With the Tair I was sure that it survived :D I had to disassembly the lens because the previous owner oiled the aperture blades and they were stuck (at least it was a reason to greatly reduce it's price :D) and I was amazed by the construction of this lens. The frugality and simplicity of this lens is really amazing :D and yet in my experience it still outperforms the other 4/300 lens (like the CZJ Sonnar and the Pentacon one... I only have this 3 battleship type 300mm lens :D) and it's much easier to use with it's machine-pistol style grip :D not to mention the reactions around you LOL So I believe for their price the russian lens perform quite well, and you can buy 2nd hand ones much more cheaper. You're paying for not only the picture quality of the lens but for the feeling of the russian lens :D Cheers, .timber Sandy Harris wrote: > New Russian lenses, $250 for 135/2.8, $100 for 135/3.5. > http://www.rugift.com/photocameras/lenses.htm > Are those any good? -- 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.
