There is also the amount that it would need to move would be a lot more than with normal SR. Although you could almost do it if you put an APS sensor in a 645D body. The 645 lenses (especially the film ones) would have a large enough image circle. But, it's not like Pentax can afford to start making niche cameras. -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
