Hi all! This weird Soligor lens arrived today in the mail by mistake (the wrong item was posted to me). I have no idea what mount it is and if it could be adapted for use on my M42 cameras. Some sort of adapter was snugly fitted at the back with the use of carefully placed electrical tape. The "adapter itself has three screw holes that are semi-destroyed. The lens itself seems to have preset aperture control. I don't know if the rear detachable part is really an adapter or just the rear part of the lens that has broken off. Without the electrical tape there, it is very loose when placed at the back, perhaps the missing screws held it firmly in place? The lens itself is strongly reminiscent of the Super Takumar 3.5/35 I have in M42 mount, both size- and design-wise. I have come to an arrangement with the seller to simply keep the lens for free, so I was wondering if it could be easily fixed or if I could just get another adapter for it.
