'Cause I just grabbed one for disgustingly cheap and was blown out of the water by it. The lens was made in Japan, and has the same metal hood design as the Sears 135mm f/2.8 that I own.
One of the first things I noticed is that I can get a soft focus effect if I crank the aperture wide open and use the lens at its wider end. This clears fairly quickly once I start stopping down, but I kind of like it.
I don't actually have any decent shots up yet from shots at 260mm, but thats mostly because I had so much fun taking the close focus stuff I kind of forgot about the fact I actually bought the lens for the zoom aspect of it.
Otherwise, it shoots nice and crisp. It also renders pretty smooth bokeh all the way through its range, which surprised me (in a good way).
This is a good example of the smooth bokeh at the smaller apertures - I think I shot this at either f/22 (the smallest the lens goes) or f/16.
