While it's a full-frame lens, it's fairly obviously intended for DA/DX format bodies (Where it's a 105mm equivalent). There's just no real point in making a subframe telephoto prime when it's easy enough to get full frame coverage (Why Canon did that for the 60mm EF-S I can't understand, especially since replacing the 50mm EF Macro should be a high priority for them). -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
