Can't Sigma fix the older lens(es) so that they _do_ work? I had a relatively old Sigma 50 mm F/2.8 EX macro that didn't work on my 5D, but Sigma fixed it for me for about EUR 50,-.

Sigma stopped rechipping older lenses years ago...

They stopped this repair program quite a while ago, probably because they ran out of parts.

Hello Thomas,



No unfortunately Sigma does not repair their 400mm/5.6 APO Macro HSM anymore, I gave them a ring in 2009.





Best wishes,



Reinier
