Lens dropped and now it is tilted inside and won't focus

My Canon EF 50mm 1.8 mkI lens was dropped and now the lens assembly is tilted inside the housing so it won't focus. Has anyone taken one apart? Anyone ever tried smashing the part shat is sticking out to try to get it back even?

I have taken it partially apart, including unslodering some of the ribbon wires, but can't go any farther as the motor assy is blocked from removal by a protruding screw hole in the plastic housing.

Does anyone have instructions on how to take this lens apart?

I had a camera with the very same problem and decided to take it apart. After all what was there to loose.

It sounds like you have more to do than I did. after undoing many screws I was able to take out the zoom lens housing. I was able to disconnect the motor from the main body. I also removed the CCD board.

I then removed the rear cover which housed most of the mechanics for the focusing and shutter operation. This was quite tricky as it is a very tight fit, and had to be wiggled out very carefully.

When I looked inside the main body I could see several metal pins which were wedged between the outer shell and the lens holder... a bit of force was required to seperate these. Unfortunatley the holders for the metal pins were broken, and there seemed to be nothing I could do. But I decided to try and super glue them in place. A bit of trial and error and i managed to get them all back into place. This bit is really tricky as there are several tracks for these little rods to fit into and not getting them right will make the lens not function.

Your model may be different but I suspect you will find that the metal rods which move the lens back and forth are loose and that the holders for same are broken. If you have a lot of time and patience you can get it working as I did mine.

Feel free to contact me if you need more info. (I knew I should have take some photos whilst I was doing it.

Can i strip and clean the inside of my Cannon EF 50 mm 1:1.8 II

I don't think so. the lens is held by 3 or 4 internal plastic hook clipping type . send it to canon cost about 30 bucks. one clip breaks, you can say goodbye to your lens.

Canon 50mm f/1.8 lens is not focusing.

I had the same problem with my ef 50mm 1.8. I used it on a cold day and broke off one of the internal gears. I used it for almost a year before I got the guts to take it apart and fix it. There are instructions online on how to take it apart, scary at first but not that hard overall. I used a small drop of crazy glue on the gear, put it all back together and just like new.

My 50 mm 1.4 won't focus on closer objects only far away now after my mom dropped my camera. What can be done? Is it most likely broken?

yes thats a fair bet,,, it could only be the lens that took the brunt of the smack it had and its now jamming when you try to focus up on close ups,,,

Dropped the lens, the focus ring won`t move

You can send it to the canon-service but i think it will be cheaper if you buy a new or used one.

If the AF motor is still alive + spinning, this should be fixable without any replacement parts.

Ef 50mm f/1.8 II not auto focusing

You need to send it in for service. The more you use it with the "noise", the more you are potentially damaging the auto-focus drive mechanism of the lens. The sound you are hearing is most likely the gears and whatnot grinding away at each other because they were knocked out of place by the impact of the fall. I don't know how much this will cost, but I would say somewhere in the $200 range would not be unbelievable. Sorry I don't have any good news, but I have "bounced" a lens or two in my time.
