there are two versions of the tamron. one with 49mm filter thread and a later version with a 55mm filter thread. which one did you test? I think they are the same optically so it probably doesnt matter much other than build quality, the 49mm version one is superior to the 55mm version.

Of course. But I can only test what I own. And because these are both affordable and popular I thought a comparison was in order. -- 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. -- 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.
