This should be very interesting once the lens comes back from Canon service ;)
Yahoo auctions used Canon 135mm f2 L EF lens.
This lens arrived very quick, but having to wait for the Fotodiox EF adapter another 8+ days, I though, oh well lets send the lens to Canon service, and get it adjusted and cleaned of the dust particles I could see inside the lens. Note the lens was only about 650$ on Yahoo actions, but had the dust particles in it. Otherwise great condition, and no scratches or otherwise :)
Together with the Fotodiox EF adapter below, this combination is poised to produce from great quality pictures. Jay over at Sonyalphalabs.

Below are some random shots I snapped during my launch break while taking a walk in the Mita area. (all handheld) ʕु•̫͡•ʔु ♥
