I was with a friend that had borrowed this lens from another friend and she let me test that lens with my camera. I just wanted to see how sharp it was wide open and the depth of field created at 300mm. Astonishing lens, amazing quality and built like a tank! My trusty Canon 600d with this lens is heavier than a Nikon D3s with 70-200 f2.8 VR II. Anyway it was a great experience and i hope i would have the chance to play with it again in the future! Have a nice Sunday! via 500px Jokerf1 http://500px.com/photo/104672371
