Hello All
I have been meaning to post a little ditty on this lens for a while. Have finally gotten around to it. This lens does not get a lot of attention for whatever reason. I think mostly it is the fact that it is in Contax RF mount and not terribly common. Mine is an early West Opton version. There are other versions as well. The thing that makes this lens more interesting presently is the ability to use it on M Rangefinders as well as m4/3 cameras with adapters. I have an older possibly homemade adapter from un-known source. It has a heavy action but does focus accurately. Too heavy for the tiny Opton 1.5/50 so I ordered a new adapter from Amedeo. Here are some samples from this lens. Please comment away. All of these were taken with either an RD1 or M8.

It doesn't get as much mention, because this board is Leica-centric.

Most of the Japanese lenses from the 1950s were based on Zeiss designs, including the great f/2.0 85mm Sonnar, which was first developed in the 1930s. More than 70 years later, it still delivers excellent results.
 
Try www.photobucket.com for free uploading images. It gives you links that directly can be posted here.

So does flickr! You just have to right-click on the image itself and choose "copy image location."

I would like a copy of this lens someday, to be sure!

EDIT: a nice looking set--I can't believe we weren't already flickr contacts.

From Flickr: click on the "all sizes" option. Use the absolute address of the image, ie the second address given on the page, in the BB statement. img /img statements.

My late Zeiss 50mm F1.5 wide-open, on an Amedeo LTM adapter.

A very nice set from a great lens! What is a reasonable price to pay for an excellent copy of a post-war 85/2 Zeiss Opton or Carl Zeiss lens? I would really like to have one in my Contax bag.

Best regards

I've shot the Nikkor 8.5cm F2 in LTM against a late black LTM J-9, and a Nikkor 8.5cm f2 in Contax mount against a 1975 J-9 in Contax mount. The Nikkor is sharper and has higher contrast.

I have to rebuild a 1959 J-9 in Contax mount. Glass is perfect, but some looseness in the helical. Just got a 1958 LTM J-9. The latter appears spot-on from 1.8m through 20m. I'll be shooting another comparison.
