Latest Review Posted | Cosina cosinon-w ( Petri ) MC 28mm F2 I really love this lens. It is small, fast and sharp. Colors are no pro and no con for me, mine doesn't produce pictures with much contrast, but it doesn't look bad either. The only thing that is not so good about this lens is its behavior in situations where you shoot against the light.
By the way, I have the "MC COSINON-W" version of this lens, not the petri one. I don't know if there is much difference.
On crop this was the lens i used for everything. On film its pretty wide but you still are able to get some nice Bokeh. Anyway, the pictures may be better at showing you why I like the lens :) (All shot on a Canon 550d with minor postprocessing)
