Bandwidth is the problem here. To shift the data for a 14MP image out of the sensor in 1/200 of a second is going to require a data transfer path than can process 3 gigapixels/second. It's hard enough to get a memory bus that works at that speed, let alone a multi-channel ADC. An HD video camera can process around 2MP in 1/60 of a second, so we are just about an order of magnitude away from what you are looking for; that suggests we'll be there (at an affordable price point) within a decade. -- 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.
