From engaged enthusiasts to plain gullible.

Don't forget to also thank Nikon, and Zeiss.

Above is a selective quote from LensTip.

I can do that, too:

• "I am pleased that the new lens is much better than its predecessor in almost all categories."
• "Its high build quality and good optical properties are exactly those features professional photographers are looking for. "
• "In regard to that aspect the lens won’t disappoint you for sure."
• "You must honestly say, though, that when it comes to the resolution the Canon, along with the Nikkor and the Sony/Zeiss, fares the best, leaving all the products of the rival companies far behind."
• "the fact that new constructions, with cutting edge optics and mechanics solutions, have to be expensive. Their designing and production have involved considerable financial outlays which should be returned."
