With top quality lenses, there is nearly twice as much detail In a FF image as a aps image, this is because they both have Relative same lp/mm and the FF image is much larger.

It's physically inevitable that, given an equal number of pixels, a 24x36 sensor will have larger pixels and hence lower noise than a 16x24 sensor. Perhaps technology will lower all noise levels in the future to the point where the difference is unimportant, but I expect we're past the point of diminishing returns now and approaching the limits of physics: Noise, more than absolute pixel count, is why full-frame is growing so fast. Here's an interesting observation, too: The 4/3 lens mount has the same opening diameter as the Nikon F mount (44mm), so larger sensors *could* be used in the 4/3 system in the future. They'd require a new line of lenses, of course, but all the manufacturers (except Sony) are in that boat to one degree or another. I wouldn't be surprised to see larger sensor 4/3 cameras appear after the micro 4/3 gets established. -- 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.
