Hi all,

I damaged my sigma 10 - 20 when in Berlin last month. I have a tamrac adventure 6 backpack which I store all my stuff (just) and I normally have the camera strap hanging out the back of the back pack (not any more).

As I was walking down a street the strap caught on a street bollard type thing and wretched the 510 and attached sigma straight out of the back onto the floor, I was gutted, however the only damage done was to the lens as the pics below show.

The lens no longer feels firm and can be moved slightly on its mount. I've attached another lens and that feels solid so I know its the Sigma. I don't understand how that little crack has caused this loose feeling.

Sigma are wanting 70 to fix which I can't afford at the moment so I'm thinking a big zip tie around the broken bit of plastic may secure it again without marking the lens incase that causes issue with the future repair by sigma.

Any thoughts on how such a small bit of plastic can make the lens feel loose? Do you think it would be safe to use in the mean time?

Cheers

First thought, any chance travel or household insurance might cover the repair and, second, 70 seems very reasonable to me.

Like modern car bumpers, I wouldn't be at all surprised if that cracked plastic is just the external evidence of more seriou structural damage.

Damage may look minor but I think the lens may now have slight front focus at certain parts..but since that lens is f4, the DOF may hide that focusing issue.

Cheers Ian,

I emailed the pics to sigma and they reckon 64.99 to fix the lens which like you say ain't bad at all..

Will be sending it off on Monday, still gutted and annoyed at myself for being so careless :mad:

Hey Garry, accidents do happen. Lucky it's only some minor damage and not something major.
