Just paid a visit to Sigma today.
Was told that it would cost me $130 to fix a faulty aprture, change a printed circuit film piece and do 'whatever was necessary' to make the lens work.
The lens was working perfectly fine before, with exception of the 'sticky' aprture.
No compatibality problems, no fungus, mininal dust (heck, I couldn;t see any), no front or back focus issues ...
So what do you guys think about the $130 they are asking for? Is it justified, or am I being taken for a ride?
