Yea, I had to send my first lens into them 3 times to get it right. But oddly enough the optics were very good. Just fljljlkjl QC issues or lack of. I agree it is a pain in the ass. But if not in a hurry ok, for me anyway. I particularly like the MTF charts though. It gives me a rough guide to performance. I really want to see some pics with it.

This test on Canon 5D looks pretty descent to me:

Sigma AF 120-300mm f/2.8 APO EX HSM DG OS (Canon EOS) - Review / Lens Test

It's still on my wishlist, so Sigma give it to us!
