After noticing that my Voigtlander 50/1.1 didn't seem to be locked in properly on my M3 as I was focusing it, I moved my hand to twist it the rest of the way on and felt the lens slip from my grasp and watched it smack into a tile floor. Ouch.

The result is a badly bent filter ring, and it seems a new, slight wobble to the lens that I don't recall being there before.

I was going to post this for sale soon as I don't use it much, but it seems like maybe now I'll have to fix it an use it for a while.

FYI: I was not trying the "pro" one handed lens change at the time.

Chris - sorry to see the damage. If you want to fix it yourself, here's a trick I use whenever I buy a used lens with damaged filter ring - get a piece of hard maple, cut/file a concave semi-circle the same radius as the undamaged section of the lens, then a thinner piece of maple - this time file a convex shape on the end same radius as the inside filter ring on the end. Lay the damaged section on the block and then tap the thinner piece with a hammer to push the damaged section back into place. Works every time for me - hope it does for you should you try it
 
Check the small screws which hold the lens body to the mount. Dropping the lens can loosen these screws. Tightening them (if they are loose) may help with the wobble. The filter ring is another issue, it looks a little too bad to straighten without causing cracks.
 
I put my C Sonnar away on an M2, just resting in its mount not turned home. My cabinet shelf is about throat height. Next time I got that camera out the Sonnar hit the wooden floor. Bent the B&W filter. The lens has been fine. Another reason to use filters for me. I never ever dropped anything till then. And I actually dropped the same lens twice more. Bent a hood the second time. Three falls and the lens fortunately is still fine. I guess we all have to drop something. Hopefully your run and mine are over.
 
That sucks. I would pay the extra amount to have it repaired by Cosina. They should be able to replace the front barrel.

With this lens, I can't think of a good reason to try to fix it yourself.

Good call. I tightened one of the screws that apparently got jarred loose. No more wobble.

Also a good idea. I sent an email to DAG. Will have to contact Cosina as well to see what it would cost to replace that part.

I hope so too. The lens hood is usually permanently affixed to this lens. I'd much rather have replaced the hood.
 
When you bend metal, it stretches permanently. It will never be the same. I've been able to straighten deformed filter rings, but this one is significant. I would contact Cosina and ask how much it would cost to repair.

This lens has enough value to have it repaired properly.

That's what I would do.

Just sent an email off to Cameraquest to see about having it properly repaired.

Thanks to everyone for commiserating with me about this.
 
I said something about a wooden dowel rod, and a hammer over on Flickr. But yeah, sending it out for repair is the better option. Who knows, you may have misaligned something with that hard of a knock.

Kinda the way I felt when I knocked a Rollieflex Automat off the workbench with one of those big honking Yashica Tele Adapter lenses on it, and caved in the whole front plate.

You can buy filter ring tools designed to fix exactly this damage from ebay. Screwing it in the appropriate direction will push the dent out of the filter ring. Although I dare say its not as easy as that in practice.

Twenty bucks plus the same for shipping. Cheap enough, considering.

Peterm1 - thanks - much better than my homemade approach (although it has worked every time for me
 
If you decide that you don't want to fix it and are still going to sell it let me know. I don't mind banged up stuff and if the price is right I wouldn't mind having one of these.
