The last time I had a question about a lens, it was the Pentax 28-135 beast of a lens that seemed to have so much promise. Unfortunately for me, my example had issues and did not focus properly, and did not focus to infinity. As a result, my pictures turned out not to be very sharp at all and I ended up selling it to someone who seemed to think they could fix it. This time I have acquired a black Minolta XD11 with a hefty and very nice looking Vivitar 35-105/3.5 lens. I have never used this lens, but it seems to be quite popular on eBay. Has anyone used this lens before and if so, what do you think of it? Who made it and is it a quality lens, or just another generic, cheap lens? I would appreciate any information I can get about it.
