So did you get shived? Have you heard the words, "Bring out the gimp." in the past 24 hours? Come on... inquiring minds want to know...
Got it...I just want to thanks everyone for all the tips on how to identify refurb lens

1. Best Buy receipt is included
2. Serial number on the lens does match with the retial box and blank warranty card(looks just like regular card)
3. No red mark
4. Cosmetic looks just like new
5. It focus just like the copy I rented few weeks back. I didn't see focus shift from f1.2 t f2.8
One tiny problem, the lens has one tiny dust speck inside(rear end)

. The seller didn't even see it until I pointed it out. He seems to be very honest though. Bottom line is I walked away with this 85L II for $1525(another $25 discounted due to a tiny dust speck).
Below is one of the pics I took inside starbuck @ f1.2. This is JPEG file, straight out from camera. no pp. Re-size only.
