Some comments elsewhere got me curious about the difference in RAW sequence capture speed between DNG and PEF format settings. So I did some testing... ;-)
--- Test conditions: Pentax K10D + FA43 Limited lens ISO 800 Manual Focus (locked) Manual Exposure (f/2.2 @ 1/200 sec) JPEG settings: max compression, 2M JPEGs Transcend 150x 2G capacity card (reformatted for test) Exposure on continuous, started at sweep hit zero and stopped after one minute. Additional exposure when write light turns off. Runs of each case were repeated five times for accuracy. RAW Only - PEF - 9 frames to buffer full - 59 captures total - flush 9 sec RAW Only - DNG - 11 frames to buffer full - 52 captures total - flush 13 sec RAW+ - PEF - 7 frames to buffer full - 53 captures total - flush 8 sec RAW+ - DNG - 8 frames to buffer full - 49 captures total - flush 11 sec --- Go to http://homepage.mac.com/godders/pentax-K10D-write_perf/ if you'd like to see the data shown in QuickTime movies. enjoy Godfrey -- 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.
