The idea is that you design a wide-angle fixed-focal-length lens that has very good sharpness in the center, and not-so-good on the edges. (This is, of course, a lot easier than designing a lens that's excellent to the edge.) For the long end of the digital zoom, you crop 5 MP from the center of the sensor. You do OK, because that's where the lens is very good. For the wide end of the digital zoom, you use the whole sensor, and you downsample to 5 MP, which the lens can provide well enough edge-to-edge. -- 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.
