Seems an excellent idea.

Really interesting Attila, thanks for sharing!

Funny idea! Don't know if you get light leaking along the zipper, but a bit of black tape can be a remedy if so. Advantage is that it the bellows is short, so 6x6 folderlenses might be applicable too.
Thanks for sharing!

I've seen the do-it-yourself (DIY) LensBaby-clone idea, using a rubber plumbing fitting as a lens body. But this is better!

One thing -- rather than taking a mount from a junk lens, use a modular macro tube set. For my Pentax K-mount camera, I bought several sets of CHEAP macro tubes. Each set contains screw-together sections: the macro extensions, and male and female (lens and camera body) mounts. Those mount sections could be attached to the bag, at least on the camera side. On the other side could be an enlarger lens, or a lens from an old folding or box 6x6 or 6x9 MF camera.

I have an old Zeiss Tessar 80/2.8 from a wrecked Ikonta, with an M39 thread. The macro sections have a 60mm thread. The male macro mount could be held to the bag with a #1 (6mm thick) macro ring or with some other 60mm ring. I would structure this as:

. lens -- bag body -- 39mm ring -- bag interior -- 60mm ring -- bag body -- macro mount ring

All of that snaps right into the camera, and except for the holes in the bag it's totally non-destructive. I guess I'll have to find an extra bag tomorrow and try this!

UPDATE: My macro-module-mount idea didn't work. The sections don't have enough thread depth for the bag's thin vinyl, nor enough flanging to hold it in place. Next step: See if I have an M42 lens to sacrifice, maybe an Enna Lithagon that's a total loss. Or maybe I'll use a flanged M42-PK adapter with some carefully-placed plastic stock to hold it in position. We'll see...
