The theory is that even if some lenses don't cover 24x36mm, all of them will in fact cover quite a bit more than the current sensor size. > Speaking only for my own preferences and cognitive limitations...I find it is > enough to have to remember two angles-of-view for each of my older lenses.

Also, if you've become familiar with the APS-C size, with a sensor only half-way to "full frame", you might actually get away with shooting in exactly the same way. Or you could just attach the lens, look through the viewfinder and press that little button... - T -- 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.
