Hi, Anybody has any experience with this manual focus lens? How is the Tokina 80-200mm f/2.8 MF compared to the Vivitar Series 1 70-210mm MF f/3.5 macro. My experience with the Vivitar has been quite good and though its a stop slower than 2.8 you can get it very cheap and its very light to carry around. I am looking to get a second one and want to decide between the vivitar and the tokina. Most of the reviews I found got were about the Tokina AF version so any information about the MF would be helpful. Also information about any other manual focus lens in the same zoom range, which I could get under 200$ would be helpful. Thank You.
