Hi Miha, Nice to hear from you.

Gerard, did you try this with another flash unit? And, does it happen with 1/100 and 1/50 speeds as well? I have a Sigma 500, and I can try with that one.
Before jumping to conclusions, I did many tests: 5D+ST-E2+580EX 5D+550EX(master)+580EX(slave) 5D+580EX(master)+550EX(slave) 5D+580EX - on camera All different setups show the same behaviou: FP active at Xsync speed of 1/200 (xsync) when the FP feature is active on the flash (see following table for the shutter speed tests I did) Regarding shutter speed, I also did different test Setup EOS5D + ST-E2 + 580EX 1/160 + FP = NO FP (expected behavior) 1/160 + NO FP = NO FP (expected behavior) 1/200 + FP = FP ***UNEXPECTED BEHAVIOUR*** = BUG!!! 1/200 + NO FP = NO FP (expected behaviour) 1/250 + FP = FP (expected behaviour) 1/250 + NO FP = not possible in ETTL mode (shutter speed won't go beyond xsync when a flash is attached and FP is not active) I repeated the test on the EOS10D that I have as backup Setup EOS 10D + ST-E2 + 580EX 1/160 + FP = NO FP (expected behavior) 1/160 + NO FP = NO FP (expected behavior) 1/200 + FP = NO FP (expected behavior = no bug) 1/200 + NO FP = NO FP (expected behaviour) 1/250 + FP = FP (expected behaviour) And yes, I appreciate if you could repeat the test. Do you own an EOS 5D? Also a tests with another body (like a 20D, 30D & 1D are appreciated to narrow the scope down to the 5D, or even to my own body) greetz, Gerard. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
