It is odd, and I'm slightly baffled by it. Think I'm going to pick up an SMC-A 50/2 on friday so I can do some real field tests (as opposed to comparing disparate lenses). Right now, 55mm seems to be working better than 50mm as a setting for my SMC-M 50/2. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
