got my lens + focusing screen yesterday. Thoughts: Lens hood is flimsy and the mount isn't as tight as with canon lenses. The lens front cap is also a bit of a pain. Lens itself is well built and the manual focus ring a pleasure to use. The focus screen was very easy to install, even though i had never done it before, and focusing with it is easy at f/1.4. Lens makes absolutely beautiful images.
I have one question now: when stopping down to f/22, i can see a white dot a little up-left from the center AF point in my viewfinder. Is this normal, or do i have a defect somewhere? same thing with both this lens and my canon 50mm 1.4.
