As a follow up to the above...
Here is an article that states that the lens is sharp at f1.4. Now, I never like to criticize anyones work, in fact I respect every photographer I know, even if I disagree with their style, results etc. I can learn a lot from any photographer Im sure. With that said, take a look at the images in this article illustrating the sharpness of the lens. The images don't look sharp to me, do they to you?
