Bent filter ring
      #656848 - 19/05/2008 17:58

My 5D with a 24-105 lens got blown over the other week....

Luckilly the only damage is that the filter holder ring has been slightly bent in. Phew. As a result it won;t now accept a filter. The bend isn't too severe and I think I might be able to simply bend it out again.... so,

What's the best way? I was thinking of using some flat pliers with a little cloth around the jaws to protect the thread. Is this a good idea? Any alternatives? Or can this ring be easily replaced?

Advice please...? And, please don't say, 'don't use a tripod when it's that windy...!'

Thanks

There's a bit here (scroll right down) on my website. Over the years I've straightened many lens filter rings this way.

Good stuff - useful idea.
On closer inspection I'm now wondering if the lens rim is actually plastic? It certainly seems very 'light', it could of course be a light alloy.

It's a faily recent Canon 24-105 IS L4 lens. Can anyone confirm the material?

I can actually get a filter correctly threaded although doing it up it feels a little tighter than you would ideally want. I might try some very gentle work on it....

Give that this is not a cheap lens would it not be a better idea to have it professionally repaired? Should you ever sell it any damage greatly reduces the value as understandably any prospective buyer is suspicious of this type of damage.

Well that's true. However, the damage is fortunately very minor, and I don't think I will be selling any time soon, but which time it could have picked up a few more dings (although hopefully not...!), so I'm more converned about it functioning well rather than any purely cosmetic probs....

Geoff,

If you can get the filter to screw on, it may straighten itself out eventually. Maybe try a wee bit of vaseline as an aid.

Used to, in the early days (1970's to 1990's) now it's all onshore, bringing your fuel ashore. The longest offshore-trip I had was 4½ weeks and the only vaseline I used was on my hands to........... Nah, you won't believe me anyway.

I would get it professionally done ... it is a very simple job with the correct tool.
many years ago they used to sell them in popular sizes.
You just screwed then in and they forced the dent out.
