I just bought this lens off of a seller on eBay and he neglected to tell me that the lens was dented near the filter threads.. great!
Here she is:
I'm very handy with tools, and I've got the patience to do it myself.
Do you guys think that it's more or less an easy fix? |

Hi there.
Fixing dented filter rings is rather hard. I`ve tried it once, but failed to get the result I was hoping for. In your case, the dent is very small and it looks to me that even with it, you should still be able to put on a filter . Am I right ? If so, I do not see the necessity of trying to straighten it out. You might end up making it worse or scraping of the paint. However, if you really want to fix it I can only give you one advice - do not try to give too much force when trying to bend it.
If I were you I`d leave it be.

Thanks for the reply, Drack.
I haven't tried putting a filter on it since I don't have a filter for this thread diameter. It's honestly just the cosmetics that are bugging me right now. If I found out that a filter can't screw on, I'd be a little more furious.
How easily would this bend back into shape? I would start by cutting a rectangular piece of wood (oak) and use a jigsaw to cut a semi-cirlce into the end of the wood that would be tapping the dent in the lens. Using a hammer to tap the wood, I'm assuming that since the lens is aluminum that I wont need to tap too hard? I would use electrical tape or a cloth to protect the paint, so I'm hoping that's enough to protect from paint loss.
If I were to use pliers.. I can totally see the dent getting uglier.. so I'm leaning more towards using the wood-tapping method.
Thoughts? Should I really just leave it be? Is it really that risky? |

I had watched camera repair men straightening out dented filter rings of lenses of mine with wooden mold support and a wooden 'punch', but they seemed having to hit quite hard!
I tried once myself, and because I didn't have satisfying results or was impatient I made the mistake and went on using pliers, and even though I had tried to protect the paint with tape I certainly made it look much worse 
Wooden tools look like the way to go, but expect having to hit quite hard, be careful!

In reading this thread, and also a similar one less than a week ago, it occurs to me a press might do a better job here than a hammer. You would still use the same wooden tools/fixtures, of course. But careful use of a small press would allow pressure to be exerted in a more controlled fashion than would hammering. For those not owning a press, perhaps even a vice could be used. |

UPDATE:
I made a jig for my lens and gave it a few taps with a hammer/piece of wood that I specially made and it's looking better!
I might give it a few more taps later depending on how I feel.
P.s. Ignore the injury on my thumb.. I still don't know how to use a drill, apparently. |

Wow, nice job. Now it looks like everything is back to normal. A filter should really screw in nicely now
