I laughed out loud some years ago when Ken put up his "review" of the Nikkor 45mm f/2.8 P lens; a rare, specialized, modern, computer-aided design of the famous Tessar lens design of the prior century. He never had the lens in his hands when he reviewed it. He criticized it quite soundly in his "phantom review"...turned out the lens was one of the absolute best Tessar designs ever made--due to both Nikon's skill and capability as a lens making company and because the Tessar lens was initially designed in 1902, and Nikon used modern lens coating methods and internal lens baffling and computer-aided design to absolutely maximize the capabilities of this simple four-element design.
Ken took so,so,so much "flak" for his phantom review of the 45-P that he was forced to actually get a sample and try it, rather than look like a fool for reviewing something he had never even SEEN in person!!! That was a classic low point for Kenny. and as Josh alluded to above, YES, there are quite a few people on the web who appear to be paid shills for Canon gear. Many of their users are pretty sensitive about the Canon brand and any shortcomings that **anybody** finds in Canon products.
