Jupiter-13 M42

I found one while I was looking for some other Jupiter. I won't tell where, just somewhere in Europe ;s
It comes with helicoïdal and M42 mount. early production, nice glass, working.

the problem is that I have no idea how much this sells these days. A search on Ebay brings 4 years old listing, at 1500 usd (!):
https://www.ebay.com/itm/Muy-raras-KMZ-URSS-Lente-JUPITER-13-1-5x125mm-muy-buena-/191684564502

usually I buy soviet gear in Russia because I travel often there (Oslo-SPb, Oslo-MSK, etc), so my guideline for prices is Avito. Right now there's only one Jupiter-13 selling, it's in Kaliningrad, and price is 57.000 rb (!). Moreover it's a vanilla one (no SLR mount), without helicoïd:
https://www.avito.ru/kaliningrad/fototehnika/redkiy_sverhsvetosilnyy_yupiter-13_1.5125_n0390_176051350

the one that I found sells for half the price. It's still expensive, twice of what I accept to pay at most for old manual lenses.

most recent thread about this lens I found here on MFlenses is this:

Hard to answer.
Usualy this lens is not sold because ebay sellers think they have gold in hands, so they offer very high prices.
Same for sellers on avito.
If you want to sell it, you'll have to sell it more cheap than those that are not sold. I feel that on eBay, they could go for around 500 or 600$ as they are not only rare, but also interesting for photos (125mm/1.5) and a cheaper variante to Zeiss 125mm/1.5.

Luckily, I got mine for way less, (big) thank to a member of this forum.

the one I am considering sells for ~ 420 eur. Still a lot, I found on others forums, a comment from a guy in Toliatti who paid 500 usd for a vanilla (large format) in 2010, and Ebay archives have one unmodified large format sold three years ago for 750 eur.
So I guess 420 eur for a working good one in M42 may be an ok price. It will also be easy to modify it for KM39 mount (my main film 35mm SLR is the Start ...).
Anyway still damn expensive for a focal I rarely use.... Will post the link if I decide I will not buy....

With things this rare, the question is mostly: How bad do you want it?

Put a number on it, and contact the seller. If price remains > your number, walk away.

Should you decide to get it, be sure to share some images Like 1 small

How can you modify M42 to Z39 without loosing infinity? The opposite (Z39 to M42) is easy, yes.

Btw, IQ is not great at f1.5 as you may expect :

Depends on what your camera is, Zenit? you would have to get the optics closer to the sensor. Perhaps remove a shim if it has one.
On a mirrioless, you just mod the adapter to whatever register you need.

I modify the mount block on the lens.
It's DIY for each lens. Soviet RF M39, Z39, M42 and PK lenses have all same flange distance and 1mm pitch, so I do tweak PK and M42 lenses for Z39 with some cutting, boring, grinding, sanding, epoxy, optional springs and levers removal/tweaks ... the general idea is to epoxy glue a M39 thread on a plate instead of the M42 or PK one, being careful to keep correct flange distance.
For instance a Tokina AT-X 357 35-70mm PK to M42
Or in case of Tamron Adaptall I do an Adaptall-M39 so I can use the range of lenses: Tamron adaptall M39 adapter
Some lens are easy, some tricky, some may be too much work.
This summer I want to do an easy one, the Vivitar 17mm/f3.5 and I just found a cheap Mir-20 old style whose mount I will modify also to M39 (easy to do in this case).

I like the Start, it has full-speed range Zorki-4 like 1s to 1/1000, nice split ring viewfinder, film knife and there is an M39 adapter ring for it.



here with an adapted Tamron:

I decide I won't put this money on a lense that will see little use anyway (I shot mostly ultra-wide to normal focals).
Sometimes I find stuff on allegro.pl. As a foreigner you can't register a full-blown account ie. with on-site payment capabilities but you can still contact sellers to agree for off-site transaction (regular bank wire ie. SEPA/SWIFT).
So here it is, for 1800 złoty. I bought stuff last year from this guy, payment by wire, fast delivery, I experienced no scam, communication was good and actually genuine. It's in Tomaszów Lubelski, the town near the infamous Bełźec, so not very far south of Lublin so in case someones wants to check before buying easy logistic. Communication tolky po polsku, kurwa.
Whatever he writes on the ads, I guess he just gets old soviet stuff from attics and probably also from over the border, as he is few kms from Galitsia. Cameras are often as-is, but he checks lenses.

Interesting this lens (exemplar) was for sale in Ukraine.

EDIT : In fact, since the photos are exactly the same, then it's the same seller.
