The reviewer certainly loved the 50 Art on his Nikon. Do Nikon shooters have fewer autofocus complaints with this lens than Canon shooters?

Quite likely. I believe that Nikon has shared their AF algorithms with 3rd party vendors, whereas Canon has not. That makes the reverse engineering more difficult for Canon mount lenses.

I had not heard that. I had heard that Nikon was not only making third party batteries incompatible, but was trying to find a way to do the same for lenses. They are hammered a lot due to the better performing third party lenses coupled with the high prices for Nikon lenses.

It was likely a phoney rumor, but there may be a grain of truth there too.

Recent reviews include Ken Rockwell, who also says this is the sharpest lens he has ever tested.

http://www.kenrockwell.com/sigma/50mm-f14.htm

Listing Ken Rockwell as a source, a reference, an expert, etc, is absolutely silly and mind boggling. Here are some other things that would be akin to it.

-Listing the National Enquirer as where you got your information
-Citing Wikipedia for a paper that is to appear in a peer reviewed journal
-Saying you will never drink again after you vomit from last night's drinking
-Obama saying he would end the wars overseas

Just don't do it man. You just come across as a troll.
