I ask this because I'm going to (depending on demand) be making a run of 20-40 58mm-threaded (we could potentially do other diameters, if necessary) bayonet mounts at a friend's machine shop. These will most likely be made of lightweight aluminum, although plastic is a possibility.
Please let me know if you'd be interested in having one of these for your more-often-used lenses.
