I am not sure what information you are looking for but let me add a bit more information to the description.
I acquired the lens about 2 years ago from a forum member. But since then I have used it only occasionally because of the weight and size. In my opinion, this lens takes a lot of practice to master which I have not. Thus I am selling it to finance the purchase of another lens. The lens is front heavy so you will need a long plate on the lens mount to balance the lens when set on a tripod. As with some older lens, this lens is prone to purple fringing under high contrast conditions because it is not designed for digital cameras. However, the problem can be corrected by post-processing.
The lens surely have a long reach. The focus ring is very smooth and precise. Very easy to use. However, depth of field is paper thin, coupled with the long reach, it surely take a very steady hand to get sharp pictures.
I have not kept a good tab on photos taken with this lens but I will try to find a few and post them tomorrow.
