THE PROBLEM IS THAT AT CURRENT PIXEL DENSITIES OF THE SENSORS (fairly high relative to lens resolutions), THE LENS'S RESOLUTION IS STILL A MAJOR FACTOR OF TOTAL SYSTEM RESOLUTION.
My point was that in order for you to continue making the sensor smaller and smaller than APS without losing ANY system resolution, you would need perfect lenses of infinate resolution. Going smaller than APS is worse, not as good as APS for the system resolution. Going the other way, towards FF is better way to go because the overall resolution of the system will increase with same quality lenses as today, even if you kept the sensor resolution the same (just bigger, FF, but not higher resolution sensors).

There are no infinite > resolution lenses. Wouldn't the lense merely have to have sufficient resolution for the denser sensor, not infinite resolution? If you want to extrapolate the process _ad_infinitum_, of course, to television-crime-show levels of zooming-in ability, yeah, but given the real-world examples of the K10D and K20D, and 300mm and 400mm lenses, we should be abe to calculate a finite lens resolution that would be enough, wouldn't we? Or am I missing some crucial step? -- Glenn -- 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. -- 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.
