Broken lens - shaking internally

[danielfellowes]

I have a Sigma 18-200mm f/3.5 - 6.3 that I've had for a good few years, recently it's started playing up. When I look through the viewfinder, it's clear that something internally is shaking from side to side. It's a small vibration while it's not doing anything, gets very severe when trying to focus, and usually but not always stops when I actually take a photo. Is there any way to fix this or is the lens a goner?

Thanks in advance.

Had something similar with an old sigma lens, unfortunately the cost of repair wasn't economical viable. Depends if you have a good local camera shop that could make a repair assessment on your lens, otherwise you would have to send it away, or google about trying to take it apart and seeing whats come loose or broken inside.

Is this the OS vesion, if so you could try switching the OS off and see if it still shakes.

Ooh good shout, dizidav. There's no shaking while the OS is switched off

Probably just wear in the lens, should still be useable as a non OS lens, Sigma do have a fixed price repair tarif, never used them myself so cant say how good the service is, maybe worth a call.

I had the same with my 5D3 and 24-105 and Canon repaired the OS and aperture assembly.
