I've noticed that the archive threads have been overloaded with more discussion about the problems people have with a lens than what the archive was meant for...posting images taken with the lens.
I'm sure a mod can help me with this but we should start a thread addressing the problems with a particular lens in this forum instead of having to flip through several pages of people complaining about problems with a lens in order to view sample images. I guess this can be the start for it but I don't know about how well it would work having a complaint/problem thread for each lens listed in the archive.
The one archive I see a lot of this is in the Sigma 24-60 thread. I own this lens, second copy, and I haven't had a problem that I can find yet. There are, however, a lot of others who seem to have had some problems to some extent.
With all that said, for those of you who like this idea, post away with your complaints, problems, experiences with service centers...etc.
