HI Darren - Thanks for looking. All of the shots were on a tripod and most of the macros were with the self timer. The bird shots and the shots with the XR Rikenon were not taken with the self timer. I should also note that the K5 and film bird shots were not taken with the self timer either Mark -- 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.
Re: Testing some K Mount lenses on the Q
Thanks, Igor! I edited out the reference to the A* 3900... I promised Pentax I'd keep that one a secret...

I got a K-to-Q adapter shortly after getting the Q itself, but have been using it mainly on a copy-stand with the A* 200mm macro for extreme macro shots of electronic parts including the inside of memory chips (and it works very well for that :-) I still want to do some tests with the FA 50mm macro, which should be pretty good on the Q for insects and similar small stuff, but unfortunately the focusing ring of the FA is not very well suited for manual focus. I also have a M 100mm f/4 macro, which DOES have excellent focussing but it is a tad long perhaps ... >Summary: Some lenses work well, others, not so much. > >But then, how good do you ever have to be, really? Better never hurts, awaiting the new 06 zoom lens (80-250mm f/2.8 equivalent), which should be a nice complement to the standard 01 which is the only other Q lens I have. Regards, JvW PS: The upcoming Pentax K-to-Q adapter seems pretty expensive, I saw a price around 250 dollars mentioned somewhere ... -- Jan van Wijk; http://www.dfsee.com/gallery -- 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.
