An alternate strategy to think about: As Bill mentioned, you have an option on the K-1 to shoot full frame, APS-C crop, or Auto. The new little mode dial makes it easy to switch. So get the K-1, get the D FA 24-70/2.8. Use it full frame. Except when you force it to crop mode, and then you have a 42-105… The open question is how good the K-1 is as a pseudo APS-C camera compared with the K-5 or K-3. Is it as good or better even in this mode? [For values of good/better which lie somewhere in a multidimensional space with dimensions such as Resolution, Tonality, Resistance to noise at High ISO, Dynamic Range, etc.] stan > > > -- > Larry Colen l...@red4est.com (postbox on min4est) http://red4est.com/lrc > > > -- > 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. -- 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.
