I haven't been shooting for a few years and I haven't been around here in quite some time, but I hope I can get some answers from my old friends.

Recently I pulled the camera out of storage to take some photos of a friends band at a bar as a favor. Long story short, some drunken idiot (ME) dropped my camera to the floor and dented the rim around the front (see photo).

Does anyone thing Canon will fix this? The lens is a 24-70 L.

Do you use filters?
Can you still put on the lens cap?
If No and Yes then you might consider leaving it.

I'm sure you can get it repaired... but it might cost a few hundred dollars.
What is you pocketbook pain threshold?

If nothing else is damaged, it is not a major repair, but it is not cheap. I had this on my 70-200 when wind blew my tripod over. It cost me about $135 at a reputable local repair shop. However, with this damage, I would want the lens checked to make sure no elements were knocked out of alignment. I was amazed that when mine fell onto concrete, nothing else was damaged.

I once dropped at Sigma 20-40 EX on the cobbled ground. I had a £120 Hoya Pro1 UV filter (82mm hence the cost) on the lens. The filter smashed, but the filter ring bent, instead of the lens itself. I had to have someone remove the ring as it was jammed on. I never bothered to replace the filter, but do sometimes think that it might be a good idea to put a filter ring on to save the filter thread in event of a repeat. I was lucky that I did not do any other damage to the lens. As it's a constant f/2.8 it is my standard zoom, I got it for my 300D before the 17-5? crop lenses were readily available cheap enough for my pocket, so it still gets a lot of use.

you can also fix it with a pair of needle nose pliers and a wooden dowel rod. Use the pliers to get it close and the dowel to push it back in place and smooth it out. It wants to be round.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

Here's a thread from six months ago where i posted the same reply as above. Good luck and keep us abreast of what you do that dent.

Thanks for the info everybody. I am going to bring it to the canon service center here in New Jersey. It seems to be miss focusing now. Probably banged up pretty good.

That's a shame. Hopefully you'll get away with the minimum repair cost, which if my 100-400 is any indication, would be around $260 plus return shipping.

If that's a currently in-production model, or even a relatively recently discontinued one for which spare parts are still available, I'm sure Canon can fix it.

Just be aware that a factory repair facility like Canon's will replace any and all damaged parts modularly, so the cost can run rather high.

The obvious damage - the filter ring dent - is actually the least of your worries. Over the years I've straightened out many of those with simple, non-metallic tools I've made myself. I first used hole saws of various sizes to make hardwood "anvils" to rest lenses of various diameters in, and then used a variety of plastic and wooden objects (hardwood sticks, toothbrush handles, etc.) to make "stakes" that can be used to get in there and push the filter ring back into proper shape. Metal will want to return to shape for the large part and this type of straightening repair can usually be made fully usable, though there might be some cosmetic damage still evident. Sometimes I can just "press" softer and thinner metals such as aluminum back into shape by hand. Other times some gentle and careful "encouragement" tapping on the stake with a small hammer is necessary. Alternatively, there are special pliers and vices available to repair filter ring dents, some of which aren't cheap. But I've found the results with those no more satisfactory than what I can get with the tools I've made myself. In fact, often a metal tool ends up doing more cosmetic damage, scratching the lens' finish (touch up is possible, but never as good and durable as the original finish).

At any rate, the filter dent is rather easily fixed. Canon will just replace that part of the lens barrel. An independent repairer would more likely just straighten it at lower cost, unless you insisted on replacement (in which case they'd have to acquire the part, too).

Actually, more of concern is internal damage, especially since you mention that focus accuracy now seems off. It might be as simple as recalibrating the lens. Or it could be as complex as broken parts or a decentered element or group of elements that need repair and/or replacement. Some disassembly will be required for that and at a minimum there will be some labor charges.

Send to Canon, if you prefer. You can be sure that their repairs will be good and they'll warrant their work, too. But an independent repairer might be able to fix it well, too. Maybe at lower cost. There are still some good repair techs around. If the lens is an older one, discontinued and with the replacement parts they deem necessary unavailable, Canon may not be able to repair it. In that case you may have no choice but to have an independent repair tech deal with it.
