I got used to the lens very much and would not change it for anything. He is worth his money. Neither a tamron nor a sigma of the same kind lay nearby. There is a stub, fast accurate autofocus, accurate color reproduction like on an Elk, aperture - everything is there to be able to make a good shot. All images without processing were taken with this glass at 500D can be viewed here http://fotki. . Ru/users/lelik-177/
