Rearranging my M lens line-up to pay some bills...
Leica M 35 Summilux ASPH - $3,000 Net [SOLD]
Serial number: 4006834
Includes: box, leather case, caps, square hood and hood cap, manual, and original retail receipt
This lens was purchased new in May, 2009, and I am the second owner. The lens is in excellent condition with very minor signs of use (no dings, scratches, etc). There are some minor scratches on the square detachable hood. Glass is pristine. Lens is 6-bit coded.
I love this lens, but had to decide between this and the 28 cron, and decided on the 28 cron (edit: I also added a 35 cron) as it provides better spacing in my kit. I have not had issues with focus shift on this lens, but have not done any detailed testing for it. At normal portrait distances, and for landscape use, I've not noticed any shift. The lens is a stellar performer on my M9, and focus is spot-on.
Leica M 90 APO Summicron ASPH - $2,000 Net [SOLD]
Serial number: 3893740
Included: Original box, leather pouch, caps, and manual.
This lens is 6-bit coded, and was adjusted by DAG for perfect focus on my M9. The lens is in excellent condition with very minor signs of use (no scratches, dings, paint loss, etc). Glass is pristine and everything functions perfectly. Beautiful images, but a little too heavy for me, so I opted for the 90 Summarit to pocket some savings.
Zeiss ZM 28 Biogon - $800 Net [SOLD]
Serial number: 15542872
Included: original box, manual, caps, and the optional Zeiss 25/28 metal lens hood
The lens is in excellent condition with minor signs of use (rub marks, but no scratches or paint loss). Everything works as new, and the lens is a good performer on the M9. Not 6-bit coded. Got this lens in a package deal, but also have the M 28 Summicron, so this one is redundant.
