Also, I received Vivitar 135mm f2.8 T mount preset (15blades) yesterday from ebay seller. The bokeh is nice, but haze is a killer, and the lens is not sharp wide open, gets better at 4, and works the best at f11. Good for rainy weather, or evenings, or indoors. Any bright light affects my copy too badly. My poor man's Zeniton 135 f3.5 is easy to deal with lens compare to this one.
Anyway, no harm for 23 bucks, including shipping
Here is the lens at f11. I love 135mm on its original format.
