I have noticed that used lenses in longer focal lengths (e.g., 600mm) are more available and with more manageable prices in Pentax 67 mounts than K-mount. I know it is feasible to use the 67 (or 645) lenses on my K-5ii with adapter. I would imagine at that point I would have a totally manual lens which might be worth it if the image quality were good enough.
So, does anyone here have experience using the 600mm or other 67 lens on a K-mount? Particularly on a recent body like K-20D, K-7, K-5 . . .? stan -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
