Do you do lens repair? I have a sigma af macro lens 90mm f/1:28. I use it on a Canon D10. I get the "error 99" message. I have attempted to clean lens contacts and remove-replace battery, etc., to no avail.

I'm not sure if they do repair, but I brought mine in and asked for help troubleshooting and they were incredibly helpful 👍

Hi, we don’t do much in house repair, but we do lots of troubleshooting (trying a different body, checking contacts, etc.). If we identify something that requires repair we can send the item to the manufacturer for $30, round-trip, insured. Most companies receive the item, get back to us with an estimate, & then you can approve or decline the repair, based on that estimate.
