I own the camera, the lens, and a Kodak ProBack. (My 350 is also missing its lens hood--and it'd be a miracle ever to locate one.)
It is heavy and cumbersome, but an exceptionally sharp lens. You'll absolutely have to have it on a tripod or monopod. Autofocus is accurate, but as slow as most older medium format systems' autofocus mechanisms are. I have used it, however, to shoot baseball and equestrian events with excellent results. Image quality is stellar.
I have it when it becomes available long time ago and use it every once awhile, with film backs and P25 before and now with P45+. The lens is beautifully made and my is still in pristine condition, with hood, pouch and all that. I think the AF is OK, perhaps with the P45+ back, the issue is more with the AF accuracy in larger aperture than the speed. Quality is first class. The lens is quite big, when compare to the Hasselblad V or H lens of similar focal length, well balance so the weight is not too much an issue for me. The lens hood is perhaps the best made hood of any camera lens, well made, heavy gauge, store easily.
