24-70 II cracked focusing ring. **DIY FIXED**
« on: July 24, 2013, 05:00:51 AM »
Hi guys.

Has anyone ever seen this happen without dropping or smashing a lens? I just noticed it today. Pretty disappointing.

That's just the rubber, not the actual focus ring. It's a cheap consumable/replaceable part. Just look for the part number, buy it from camera parts shop/ebay/whatever, tear the old one off and slip the new one on.

Something like this, for $19:

But that's for 24-70 f4 IS, if you search for it there must be one for 24-70 II

Thanks for the tip. However I'm not paying for this, neither installing it myself, and not with a non-original part :P

Just ask your local CPS support contact. They can replace it with an original Canon part and maybe this will be for free, too.

I'm amazed by the lack of DIY spirit you guys have. It's a rubber band, pull it and it gets off. What's so hard about that?!

This place sells Canon original part stock, I bought several lens/camera parts from them. I've even searched it for you:
http://www.cameraspareparts.co.uk/focus-rubber-ring-for-canon-ef-24-7028l-ii-usm-5487-p.asp

Just buy it for 18 pounds, get it shipped take 5 minutes to install it, saves your own hassle and time without the lens.

That occasionaly happens.
Pull it of - glue it - put in on....
Cyanoacrylateglue does the trick, but watch out, first time I did it, I glued my fingers too...
DCS 3c, D2000, 1DS, 1DS2, 1DS3, D800e, D810 and now waiting for the 1DS-X.....or a Nikon D4X...

With old lenses off warranty I have done quite a few fixes like gluing af/mf switches, replaced mounts and screws, even fixed a crooked barrel. But this is an expensive and new lens, and I do not want to use the wrong glue so it never can be removed again and have Canon say, "Oh, its been tampered with, sorry no warranty".

It's not the lack of DIY-attitude, it's a matter of protecting the value of a new lens under warranty.

It's under warranty, send it in and have it replaced for free. You have 1 year. Unless its more than 1 year.

2 years, and 5 years on parts that should last longer than 2 years, pretty nice here.

I've sent them a mail with the picture asking about it. Hopefully they will be their usual superquick self and fix it for free. The spent 33 minutes from I handed it in until repair was finished last time with the lubrication issue on the 1dX.

Its pretty rare for the band to fail so soon, it was probably a manufacturing flaw, a material flaw would affect a lot of lenses, and there have not been complaints.

You are unnecessarily raking up an aggression. You are assuming that OP lacks DIY spirit or knowledge that rubber can be pulled off. If the item is still under warranty and canon would replace rubber for free, I see no reason to have either  band-aid fix of ugly glue or el-cheapo rubber. Esp if OP has time and patience.

Got the focusing ring in the mail today, it was backordered for sometime. I guess they didn't expect them to break already, lol. The rep told my the warranty will NOT be void if I change it myself, so I had a go at it. Ps, they also sent me the zoom-rubber ring in the same package, nice to have a backup. Anyway, it took about 2 minutes, including pictures.

I'm glad you got it replaced.  As you found out, its just a big rubber band, nothing technical about replacing it, and certainly no need to glue it or do some other fix.
