The straps I have mount with clips to posts that are on the topside of the Rollei. This is true whether or not the leather case encloses the camera.
Since I almost always use the Rollei with a tripod, I suspect I'll just carry it in one the several packs of various descriptions I have for this very purpose. Not as spontaneous, but using MF is as much a thought process as a mechanical image-capturing process anyway.
Not to keep belaboring a point already made... but I found carrying Rollei TLR on monopod/Rolleifix to be just as fast as strap-carrying and hand-holding.
However, if instead of a single lug, you used a square plate mounted to the bottom of the camera with a captive screw that is similar to a tripod mount plate, you could connect four thinner straps to the corners of that plate and route them up the sides to connect at the top of the camera. It would look, sort of, like a letter "X".
You would still have to undo this rig whenever you wanted to reload the camera but you would still have to do this if you used an Ever-Ready case, anyway.
The reason I like this idea is because the standard Every-Ready case is made of leather. I had the leather case on my Yashica Mat come apart on me. It needs to be resewn. (If it can be resewn.) A web system made of high-strength Nylon would give more secure support than the leather without the risk of coming apart.
The Rolleifix is one of the most reasonable accessoires if you have a Rollei TLR (the one designed for the SL I have found rather useless by the way). 40$ seem way too much, I bought mine on Ebay for 25 bucks some years ago. I would not use the carrying method you showed on the picture though, either with or without Rolleifix!
Thanks, Brian, but I would consider carrying the Rollei on a tripod slung over my shoulder even more potentially damaging to the back plate than suspending it on a strap. The torque on the bottom plate would be at the best angle for damaging same. It would depend, of course, on how the camera and tripod is carried. Using the support as a sort of a cane or walking stick would be the best option?
Let me help Slix out here. Several reasons:
1. Makes mounting Rollei to a pod easy
2. Makes changing film easier than if Rollei is screwed into a pod (or ever-ready case)
3. Is quick to use when mounting Rollei to pod
4. Distributes the "stresses" when using Rollei on a pod
