Has anyone compared the Contax 135mm/2.8 to the Yashica 135mm/2.8 MLC? I happen to have the Yashica one in need of repair (loose aperture spring) and wanted to know if it's worth repairing. The last I recalled it produced saturated colors from Fuji Superia 400 with nice OOF (Bokeh) areas. But that was a long time ago, so my memory might be skewed a bit. I do remember it mounted tighter than Contax lenses though on my RTSII. The FX-2 that it was used with is back on it's way to me sometime in January 2012, so I have some time to think about it before it gets here. It was a combo that I used seldomly though as 135mm isn't my cup of tea (19mm~50mm is more like it).
