Contax Zeiss 35 PC f2.8 (Pespective Control - SHIFT) - $1,000
Serial number: 7327695
Items included: original box, papers, manual, caps, and black leather pouch.
This lens is in excellent condition. It's very clean with only a few minor signs of use (such as some minor marks on the filter rings). The glass is clean. The aperture ring is smooth with nice clicks at each stop. The focus ring is a bit firm/stiff, which is the way I like them (avoids accidental focus shift when you are doing a set of shift/stitch pano shots).
I have used many copies of this lens, and hand-picked this one as my long term keeper. It has performed very well on my 5DII, with sharp edges/corners even at 10mm of shift. I have a PhamMinhSon WD adapter that is perfect for this lens (gives infinity focus on Canon bodies) that I will include for an extra $75.
I've sold off most of my Canon system, and moved to the Leica M9, so this lens just sits on the shelf now.
