About Jupiter 9

[pierremed]

Hi everybody,

I'm looking for this lens, but I don't really know which one is better: chrome one or black one.

Thanks for advance.

I have the black Jupiter 9 in a pentax screw mount. I had a chrome one in perfect condition in ltm but traded it for some other stuff. Both of mine were excellent. 😀

The LTM-J9's have a somewhat bad reputation. I have 2 black ones. On the first I got, focus was completely off. The second one is OK, but focus is a bit stiff. I own a chrome one in Kiev/Contax mount that is OK.

I would say, avoid LTM J-9 lenses, most of them have been disassembled without care and then reassembled badly. It is common to find these lenses in bad shape, at least in LTM. I have one at home, but it was designed for M39 SLRs such as early Zenit cameras. I tried it on my LTM cameras and it wasnt focusing, of course, since it wasn't designed to be a rangefinder lens.

Kiev/Contax J-9s are sought after, I saw one at my retail shop but had no cash then, I tried going there a week after and it was already gone *sighs* such a beauty....

Strange... all the Kiev/Contax J9's I've seen are cheaper than the LTM ones.

I have an older, aged chrome LTM. It doesn't focus real well on the Bessa R that I have, but I haven't played with it in a while. I did notice some errors when I first used it, but the picture was fine. I would say the lens is ok, as long as not on a
the Bessa R.

The Jupiter-9's are made for the Contax 52.3mm standard. I'm convinced of that. If you get one that has been adjusted to work on the Leica standard, they are terrific. I had one, and sold it to a long-time RFF member.

I should add that I replaced it with a Nikkor 8.5cm F2 in LTM. No "Russian Roulette" with that lens, they are all good.

And that long time member must be me 🙂

That J9 focus correctly at f/2, but my eyes/pulse do not ! 😛

Has a sweet spot at f/4 though, and that allows for some human error. When I was Locutus, that didn't happen.

Resistance is Futile.

After being able to focus the 50mm F0.95 on the Canon 7, the J9 and Nikkor are POC (Piece of Cake).

The problem with mine is that it is in focus only at infinity or nearby, if I put a piece of electrician tape on the part that gets coupled to the RF, I get near focus correctly coupled, but it gets far off at infinity.
I am not sure it can be adjusted to be correctly coupled both for near focus and infinity.
