>>4395868That is a bizarre problem. Probably a missing spring or something. Kinda sucks. Those look like fun cameras.
I really like my uncoated super angulons. The 47mm I have is really quite nice if you don't get near the edge of its projection. Pic is a 4x5 shot with the 47mm angulon. She wide.
You could also simply ball out like a madman and purchase this sinar lantec kit for 15 grand, lol. Widest lens is a whopping 23mm. Check the projections on the lenses because they may only work with 645. You would need an adapter to go to something like a mamiya 645 film back, which they do sell.
