Do you happen to know of something like that but with a tilt adjustment in it? I really want one for the ST-E3-RT.
P.S. Following on from my earlier post about the complete lack of power from the 90EX, I
used it tried to use it last week as fill on the EOS-M, it is a useless POS, it's only functionality is as an optical remote controller. In M mode at full power it wouldn't give even basic fill.
