A monster of a lens. With close to a kilogram and almost 20cm long, you know you are carrying a big lens. It also make it hard to keep stable, as there is no tripod mount on the lens itself. Almost a must for a lens this size and weight. Build quality is nice, all metal, constructed like a tank. Smooth aperture and focus rings but with a little barrel creep when pointing the lens down (not uncommon with large push-pull type of lenses). Just looking at this lens, you expect great results! But that's where it goes wrong....
This is probably the worst lens I have encountered. Not sure if it is my copy, the adapter, or just the quality of this lens, but the lens lacks sharpness across all aperture and focus ranges. The lens might be able to make sharp pictures (I had a few sharp ones), but it was very hard to focus, even on a tripod and using live-view. The lens has two focus rings, one for tele, and one for macro. It made it very confusing to use this lens, and often resulting in messing up the sharpness. The macro ring can also be used to introduce some softness, but that's not something most people want.
It's nice that it is constant aperture across the focus range, but that was the only plus point I could find. I plan to divest from this lens in the near future and let someone else give it another try.
