Could be, but not right now. It is a good idea, but I'm not quite ready to make them just yet. I can make add-on plates later to allow quick release.

Alastair please let me know the details of your replacement loup. If that gets the camera back a couple of inches that would help. I'm looking at using a pair of handles/lens remotes that drop down from my matte box rails to make hand holding less strain.

Alister,
I will post a picture and further details in a week or so when it is completed, anodised and appraised.
