I don't have the AF400T flash, hence I cannot comment on it, but with my _much_ more powerful Metz 60 Ct2 , I can get about 20 sequential flash exposures on TTL auto (at reasonable range, fairly wide aperture and 400 iso film) before the capacitor runs out of juice, using my Super Program and motor drive A. I may be mistaken, but I am pretty sure the Super Program can hit around 3 frames per second at the sync speed of 1/125 second. So, it would take in the vicinity of 6 seconds to do 30 frames at sync speed (or faster). What your owners manual seems to be saying is that the flash capacitor will have enough energy stored to do a continuous burst of 15 exposures under a fairly limited condition. At least that is how I would interpret what you quoted. William Robb - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
