Personally I cannot wait to purchase mine. I will when there is no backlog...no hurry.
Gee.. I have 30 days to return it at B&H for full refund. I am sure it will be a great lens tho.
One thing you can bet. I am not going to over measurebate it and spend the rest of my life here complaining about it...I will be out creating images!!!!! ;D

...but hey...I loved my original Sigma 50mm f/1.4. Had a GREAT copy...just sold it for $500! LOL...$100 more than I paid for it.as they have been backorder for a while and I had a colleague who loved the lens and wanted my copy!!!!..Hated to see it go...but I cannot justify owning that and the new one....WHAH!!!!!
I would also like to read Justin's review before purchase, as I know that that should be coming soon!
