Well actually that generic L bracket will work but not too well. What they advertise is that you can use their camera plate and the universal L bracket together - the camera plate addes a pair of pins that stick into the body to keep it from twisting, and then you attach the L bracker to this camera plate - it is not as nice as a custom fit, but it does work, and I can access all controls - actually the only control in the area is the lens release latch, and you can just barely reach in through the bracket and move it. I hope they accept e-mails too as I just sent them one.
