@craig and @bvphotosnap .... I was chocked that my macrolens not to work any more :-(
I wrote to Sigma for repair... and they told me that there are no spare parts for this model any more :-( :-( (lens is 7 years old!!!)
So, I already bought a second hand Tarmron SP 90mm F2.8 Di Macro USD (model F004) for a good price. I hope I also have luck with this one...
bvphotosnap Very sharp image and great arrangement! Hopefully you can get a replacement in the future :/
