But...but, my AF400T manual states: "In the TTL Auto mode, approximately 15 flashes are obtainable (with LX or Motor "A" attached (my emphasis) in a sequence using high performance alkaline batteries in good condition at f/1.4..." Are we to take it then that "high speed sync" is not at the same time the same as PENTAX bodies performing "high speed sequential" (consecutive frames) shooting? Better yet: should we then interpret from the above that the "15 flashes" are shot only as fast as the LX/SUPER PROGRAM bodies can recycle and not any faster? *We know Super Programs *can* shoot at 1/2000th sec. How long would (does) it take to shoot 15 shots with an AF400T in TTL mode and a SP/Motor "A" combination? - This message is from the Pentax-Discuss Mail List.
