What do I need to repair this

Got this lens in a trade, obviously mount is damaged. Not sure if I can return it

It looks like the camera mount is still on there. If it's really stuck, cutting of the flanges from the mount seems the best way to me.

Big channellocks or a vise.

I didn't even figure out that this is a whole camera mount on there... I had the impression there is something missing, but in fact it has extra parts

I'll try to get the mount off somehow... contacts are there as I can see and AF screw is inside, so it might still work if I remove the mount without damaging it

This is the correct diagnosis . You are seeing the screws and inner surface from the rear of the mount from the camera body, which is for some reason is still attached to the lens. The bronze washer is the actuator for the aperture lever that is normally inside the camera body. The locking pin does not appear to be in place and would be in the hole near position 2 in wildlifephotog's pic above, so it should be easy to remove. No expensive repair involved!

The actual lens mount is intact underneath, and you simply have to rotate the camera mount counter-clockwise to disengage the bayonet, then lift it off. It would probably be easiest to grip it with a rubber grip or jar opening pad, since there aren't a lot of places to grab on.

Ah, looks like you realized it while I was typing up my response!

Arrow one points to a part that appears to be part of the aperture controls. Arrow two points to the mount ring, with screws stuck in upside down. That looks familiar, because I do that when storing a lens that is awaiting internal parts.
I'd be willing to bet all the contacts and AF drive pin are missing. Probably some internal springs and parts too.
This could get pretty expensive to fix.
I'm a bit confused now... at first I thought something is missing, because these screws are sticking out. It looked like there is a plate missing.

Then I looked in the electrical contact holes and AF screw. I saw the contacts but I was at a loss on how can camera connect to them if they are so deep inside.

When someone mentioned that there is a camera mount stuck on the lens, then it made sense. Now, when I read your post, you say that some parts are probably missing.

I'd recommend against trying these options first, since they could deform the camera-mount and make it even more difficult to remove. I'd warm the mount with a hairdryer to try to expand it, and see if it can be taken off by hand first.

On a 18-55 its probably more costly to get parts than to buy a nice used lens. Of course you could combine a lens with front end problems with this one to achieve 1 serviceable lens and save money thst way potentially.

Duh! I totally missed the mount was from the camera body. I never dreamed someone would ship it like that. I hate to think what happened to the poor camera!

Get the the thin dark piece out of the way first. Pair of pliers maybe. The the ring should come off easy while the lens is held with the mount facing down.

Wildlifephotog appears to be mistaken. It's a little confusing at first, but if you look closely, It's definitely the camera mount still on the lens. Look at how the WR gasket is below the mating surface. All the "missing" parts are sandwiched between the camera mount and the lens mount.

Apparently, everyone is about 30 seconds faster than me in their replies!

This has the full lens mount on it, from a camera front. Somebody's camera is ripped apart, not your problem. It was done cleanly, so perhaps the mirror box is plastic? The camera mount should spin right off, but it hasn't and I'm sure previous owner tried. There must be a pin or lever that is binding it in place. The lock pin, which is near the 2 in the previous post, is missing, so that's not the holdup, but look around there closely to be sure. It may be on the black ring, perhaps a catch that is touching a screw that you can unscrew? I'm thinking that the catch for an M42 to K mount is the culprit, since that's the other locking mechanism on this mount. Look inside a camera body to get the lay of the land. This would be so easy if it were in my hands.

Once you free it, you will have to check the lens carefully for collateral damage. This was pulled out of a camera's mirror box, and that took major impact.

Innocent question... why is the camera mount still on the lens? A recent thread on lens theft... has this one been ripped from the camera because the thief couldn't find the release button?

Honestly, I don't know what that mount is doing here. This guy sent it over and his description of the item was "very well preserved, in working order..." . My fault for not checking it right there and then
I'm now trying to get something useful out if it.

At first I didn't even notice it's the mount. I thought something is missing.
