I'm after a bit of advice about getting a new QR bracket that will properly fit the Kirk L-plate I got recently. I've illustrated the problem below but in simple terms, the base of the L-plate has a thicker (1.5mm) vertical rise than either of my current (Giotto's) Arca-Swiss-style QR brackets can properly accommodate, causing an offset that leaves the L-plate (and my camera) less securely attached than it should be. I have to say that it feels solid when locked down but I have doubts about how much of an accidental knock would dislodge it.
What I'm not clear about is whether it is the L-plate or my Giotto's QR brackets that are deviating from the Arca-Swiss standard. Must I get Kirk QR brackets or will I find that other makers' Arca-Swiss brackets are more generous in their accommodation than my Giotto's items? I don't think Kirk QR brackets are sold in the UK so I'd prefer a more widely available brand if possible.
Thanks for any advice.
Edit: I just re-read my post and in case of confusion, the 1.5mm height refers to the lowermost part of the L-bracket's base, below the 45 degree slope. That dimension is only 0.5mm on my Giotto's QR plates so they obviously fit with the Giotto's QR brackets perfectly.
