jupiter 9

<p>Hello<br>

I liked to know if i can use the jupiter 9 85mm f2 with my canon 7 body.<br>

thanks in advance.</p>

<p>I guess it depends on the mount of the lens?<br>

Here I have LTM-RF versions and guess you could use them only for close ups with an adapter. Same about Contax Kiev mount.<br>

There were m42 versions of the lens too and I have seen infinity images done with a 350D online.<br>

Canon 7 is some EOS SLR, right?<br>

In case you are talking about an old LTM RF: be cautious! my copy at hand appears backfocusing severely within portrait range (tested on a digital Leica that works well with a German lens). I'll probably get some MILC with EVF to make use of my Jupiter.<br>

According to Dante Stella's site the LTM Jupiters were remounted Contax lenses constructed for a different film flange distance.</p>

<p>There are calibration differences between "Soviet" LTM cameras and all others (Leica, Canon, Minolta, etc.) So you may well have focus problems with the Jupiter 9. Well, at f/2 you'd have such problems, but probably not at f/8, where depth of field would save you.<br>

I presume you're attracted to the Jupiter 9 because it's so cheap, compared to the Canon 85/2 lens.</p>

<p>Even on an 85mm, the depth of field may cover things if you stop down a bit. If you shoot at infinity, there may be little problem.</p>

<p>Here is some fairly straight poop on the 39mm lens mount 'incompatibilities'<br /> http://www.dantestella.com/technical/compat.html</p>

<p>Where he says:</p>

<blockquote>

<p>I can say that the Nikkor 50/1.4, a copy of the same Zeiss Sonnar absolutely murders the Jupiter-3 when used on the same Leica camera. Same with the 85/2 Nikkor and the Jupiter-9.<br /> With this evidence supporting the contention that the lens distance<br />scales / rangefinder coupling ring travel on the Soviet LTM lenses<br />differs systematically from that on the Leitz compatible LTM lenses...<br /> I would guess that to promote efficiencies of scale, the Soviets standardized all of<br />their camera systems to a 52.3mm standard lens.<br /> etc.</p>

<p>As for Canon 7 see http://www.photoethnography.com/ClassicCameras/Canon7 </p>

<p>My own experience with Soviet LTM 'normal' lenses on a Canon VL2 LTM camera<br>

http://www.photo.net/classic-cameras-forum/00c0si </p>

<p>Out of interest, I looked up what the 'runet' (Russian internet) has to say on this question about the compatibility of the soviet LTM lenses with 'western' thread mounts. To my amusement, the basic sites refer back to Dante's site.<br>

I'd only add the following: theoretically the issue does not occur with the Soviet contax-mount cameras (Kievs). That said, I'd say first and foremost it is just plain hard to focus an 85mm lens on these cameras wide open, and manufacturing tolerances and 'tuning' would be enough to explain a lot of the issues users experience. I've used a Jupiter 9 on a Kiev, and I wouldn't call it easy to hit focus consistently.<br>

I like the Soviet LTM cameras particularly with wide angle lenses - where this issue is definitely covered with depth of field.</p>

<p>The Zorki mount J-9 will fit the Canon 7, but there may well be focus problems. I had one copy of this lens, and it would not focus correctly on my Leica M3. There are a few people who correct this error, which is common to much of the Jupiter line.</p>

<p>I've had no problem at all using the Soviet "Jupiter" and other Soviet Kiev-mount lenses on both Kievs and a real Contax IIa (except of course, that the wideangle lenses are a problem on the latter - not, however, on the original Contax II).</p>

<p>The Helios lens is wonderful on the Contax IIa ( http://www.photo.net/classic-cameras-forum/00bqWG )<br /> I have a couple of Kievs (one turned back into an all black "Contax II) and a real Contax IIa<br /> (<a href="/classic-cameras-forum/00bp7m">http://www.photo.net/classic-cameras-forum/00bp7m</a> )</p>

<p>Yes you can. My Canon-7s also takes J-11 to my great surprise.</p>

<p>I am not sure whether I corss-tested all M39 lenses of german (A.Schacht), russian (f/3.5 50 and f/1.5 85) and japanese (Canon, Komura) lenses on all bodies (Leica IIIa, FED1, Canon7), but I do not remember any issues at least with the rangefinder calibration. <br>

The problem with the FED lens calibration probably is sometimes due to repair attemps where the shims which are needed for aligning the lens mount for proper lens-film plane distance and parallelism are not put back in place correctly. Usually these are rings or strips of paper which get lost easily, or the repairman did not care about them at all. </p>

<p>Among the Russian lenses in LTM, the 50mm J-8 and 35mm J-12 seem to reliably focus properly and have good quality optics. The 50mm J-3 and the 85mm J-9 have a reputation for poor calibration and not focusing properly. This has been my experience as well.<br>

I have had two J-9's; one worked properly as received and the second was hopeless, it was returned to the vendor. Ditto on my J-3's, I've had about a 50% success rate with these as well.<br>

Should you decide to buy a J-9 be certain do so with a trial period during which you can return the lens. I check the performance of my lenses by photographing a newspaper page at one meter distance with the lens wide open and the camera on a tripod.<br>

As was mentioned here earlier, there are people who can adjust the shims so that a lens will focus properly. The Russian lenses are no longer inexpensive (to my wallet) and there seems little reason to repair a defective new purchase when a properly functioning example can be had for the same price.</p>

<p>I have the LTM version and it worked fine on my Bessa R.</p>
