I have a new (never used, except to do an optical test on it against other lens) Contax Zeiss 28-85 f3.3-4 lens. Lens has been sitting in it's original box, and packaging. Essentially brand new.
I would grade it 10. Only thing there might me mark from when I was taking a photo of it on my table, and I think I might have caused some discoloration on the paint marking on the body of the lens somewhere, I can't see it now, but I'm sure if I examine under bright light I might be able to spot it.
I use to collect contax zeiss lenses I still have a few more left (message me if there is a specific lens you need and I might just have it and might want to sell it) this came from my collection.
Message me if you want to see some photos of it.
I like to get $300 for it .It's hard to find this lens in such a pristine condition anymore in US. Buyer pays shipping and Paypal fees. I'm "semorg" on eBay if you want to see my rating.
In excellent, little used condition, complete with box, pouch etc. This is fitted with the high quality Leitax lens-mount adapter so it's good for a rock-solid fit to Canon EF mount cameras although this can be removed if you want to take it back to its original Contax/Yashica (C/Y) mount. £230GBP.
I can add/supply some pictures if there's any interest....
Been shooting out in the forest last sunday with the Contax Zeiss 35-70 f3.4 and 80-200 f4. The 100-300 which is supposed to be better has yet to arrive. I find that 80-200 is much better without a teleconverter attached to it, much more crisp images. Graded using filmconvert and loving it. I think the contax glass lineup compliments what filmconvert tries to do.
On a sidenote, I got lost during filming couple of times in the bush. I think I got disoriented while trying to avoid the race tracks. There was no signal and phone battery was on 5%. I hated myself for walking into the forest so unprepared. Almost went to the point of panic until I eventually found my way back. Never knew I would need orienteering skills for filming. Thank god I took minimal gear that day. Below is the video.
