Well, high-speed flash sync only works if you are prepared to accept a flash with significantly less power. At 1/6000 (and a 1/180 sync speed) the flash has to fire 32 times, once for each strip of the total frame. That means you can't use more than 1/32 of the total light output on any part of the exposure. -- 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.
