My cameras and lenses have gone through many rough environments in the last couple years, from sea trips, volcanic fumes, freezing and lots of dust and dirt.

I was thinking of taking the cameras to the Canon service center, but since I have a mix of Cannon and Sigma lenses, maybe it would be more convenient to take them to a single service center that would accept both brands.

Besides cleaning one of the lenses, a Sigma 17-70 seems to have something loose, it feels like some element of the image stabilization system jumps when zooming around a certain focal length.

So, time for a proper clean up, are there any recommended shops in Bangkok for that and what prices should I be expecting for two cameras and five lenses?

They cleaned a few of my medium format lenses in the past.

Thanks for the link, do you think they can fix the Sigma lens I mentioned?

Difficult to say. I guess it would be worth a call to them.

Definitely worth it Alex. I had a dodgy Assembled in Vietnam Pentax-FA 31mm Ltd. Awful PF off the thing, soft, ghastly and not worth £1200!!!

Sent it to Asahi Photo in London, stripped, cleaned and rebuilt with a few new parts and for £85 . . . you know what it's not bad. In fact it's great now.
