Mark: I haven't tested it yet for range, accuracy and the like, but I did check the max sync speed since this kind of test is very easy and quick. Results: just like yours - small black line at the bottom of the frame at 1/250, NO black line at 1/200 and below.


Hmm is it just me or it doesn't work (flash trigger) when the camera is in live view (my 50D at least)?


Oh yeah - great shot Dave! You and Mark have set a pretty high bar for everyone else []
