Len, I also think it's possible that the RTF and AF500FTZ have very different light capacities...like spraying the subject with a garden hose and a fire hose at the same time. You could run each hose for 3 seconds, but you would be a lot more wet on the side with the fire hose! Regards, Bob S. - This message is from the Pentax-Discuss Mail List.
