There is about a 2-3mm gap between the lip of the plate and the camera.
Did you ever make a shorter, smaller plate that will allow the use of the CP2 on the NEX series cameras?
If you don't intend to make one, can I return my CP2 for credit or something? I paid $20 for a useless piece of gear otherwise. I bought it last year I think I paid $20. I see it's been marked down to $10.
Your Arca compatible plates are very nice but I don't use the QR system.
