Hey! Nice one" I checked out some comparisons with the Tokina 50 - 135mm F2.8 to this Sigma and I must say though not as sharp as my Tamron 70 - 200mm F2.8 being slightly on the soft side it is pretty good good performer. These Images are a better example from what I've seen on the Tokina. I am after a second spare Lens and I think the Sigma might just be it. Thanks for these Images. They provided me with great examples.
