There is also the Takumar Bayonet 28/2.8, which was an identical optical formula to the later M28/2.8 and the A28/2.8, but without the SMC coatings on the glass. I have one, and have made many good photos with it. I have an A28/2.8 now, so it's been relegated to backup use. It was amusing to put the two side by side, and note the near-identicality. -Mat -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
