Only flaw? His price

What is 2011?
I recently bought for my D700, and the two really are a very interesting couple low light!
A iso 6400 and its grand opening in 1.4, you can take pictures just about anywhere at night. Its internal AF is very quiet, and it is mostly much faster than I expected (I had seen disturbing footage where the goal took a lot of time before the map) in fact it is not so I would like to reassure potential buyers that goal is a bomb
Its bokeh is MON-STRU-THEM, but I must say that the CDP 1.4 is almost unusable, so it is weak ...
Quilting 1.4 is less present, so we vignetting at this opening (corrected by the D700) but as soon as you close to 5.6, it's very good veeeeeery!
Only regret: its price. The grand opening is very useful but pay a bit expensive. Especially against the new kid on 1.8G

Amazon delivery of the highest quality. I hesitate even to buy more expensive on their site so time is short and neat package.
