I'd be very surprised if that made any difference. As I said, on the K10D it displays the limit as "24", but will continue to do so for several hundred shots if you have a fast enough card. But that's because the K10D has a fast enough processor to convert to JPEG at 3fps. There are all sorts of potential limits and bottlenecks - room in the buffer to store unprocessed images, speed of conversion to JPEG, and the final buffering and write of the processed image to the card. I would expect that your camera would probably be able to manage more than three JPEGs before stalling, because processing and write of the first shot will complete before it's time for the fourth exposure. But that might not be the case - it depends on how fast the processor is. Downsizing from 6mp to 1.5mp adds processing time; that might actually take longer than simply writing 6mp JPEGs. Without knowing exactly what processing hardware is in the camera it's impossible to predict what's the quickest to produce. -- 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.
