Excellent timing Mike in posting this "T" lens!
Just yesterday Steve (Bull Halsey) and I had a lenghty discussion about this "T" Jupiter-8 lens, I hope he will see this post and post his theory. Otherwise I'll do it if he does not respond. But it makes a lot of sense. |

Hi friends,
you remember we had a discuus in the past about "T" lenses ( I possess a Helios 40 "T" (but "T" is after name ...not after serial number)
so we had no explanations except my Finish friend which tell me "T" is added on special lenses for Artic use (low temperatures use)
who know the truth again ????? |

Hello All,
I own a '63 No-Name Contax fitted with a F1.5 Jena Sonnar. The lens coating is quite similar to the Jupiter T pictured. Im ny opinion, most, not all, but most Russian lenses which are coated do not show much color due to the coating, while many of the East German lenses show off a much stronger color hue due to the coating.
The other day while speaking with Vlad I mentioned that my 50mm 1.5 Jena Sonnar has a strong blue color from the coating and like most (if not all) coated Zeiss lenses, has a "T" designation imprinted in red along the rim of the lens along with the lens name, serial number, etc. Thr T was the designation that Zeiss gave to indicate a coated lens. Granted, the Jupiter pictured has the T attached to the serial number, but that could just be a choice of the manufacturer.
I was just wondering if by any chance there were optics supplied which could have been from another source other than the norm, or had been coated differently, or were coatings experimented with in small batches ?
The date of the Jupiter would coincide with the Jena lens manufacturing.
Just a thought.

strange... coating marks are usually free standing (in the zeiss tradition) or related to the optical definition (50 f2 T) for instance), here we have a variation on the serial number ... which could mean that the variation is not optical but mecanical... how does the lens reacts ? any special effect on the picture ?
The coating seems very blueish indeed...
and to what term a cyrilic T could lead... ?
For zeiss collectors there is the mistery of TF coating mark... but that's another story

See http://www.zenitcamera.com/qa/qa-indexes.html
Some examples:
Helios-40-T -- for a television cameras.
OF-28T -- the tropical version (named this way in a documentation, but on a body the letter "T" is always placed near the serial number).
So, as I think, this is the tropical version of Jupiter-8M (has another coatings and lubrication).
Btw, the "arctic lenses" must have a heating... ;) |

tropical == òðîïè÷åñêèé (tropicheskiy)
tropical version == òðîïè÷åñêîå èñïîëíåíèå (tropicheskoe ispolnenie)
Btw, this word is from Greek: τροπικος... ;) |

Mark, You do now realise that you're going to have to go to the Arctic AND the Tropics to take photos to test the lens properly, considering that it's not too clear whether the "T" is for Arctic use or Tropical use?

Thanks for the link Andreas. I wonder what the actual differences were between an "ordinary" lens and a "topographical" lens are?
Mark, you could always fly over the Tropics and the Arctic to take topographical photos, just so you can say you've done the full list of the things it was thought the lens was for until Andreas cleared things up for us. |

...
The main difference is only "T" letter  . So far as I know there was a special order for cameras for topographical service and this letter was engraved to separate this spacial batch for the topography from the normal serial cameras. May be there ware some improvements for "T"-lenses, but I have no further information about this.
Regards, Alexander |

Alexander, thanks for the reply and the info.
Mark, have you finished the film yet and have you had the film processed yet? |

"unspectacular" so you just left the lens on the shelf? All the results I've ever had have been "unspectacular", although a few have been "not bad" or a little better though usually showing the gear to be good rather than my skills, and even though I have more gear than I really have room for, I still intend to use it all. the 6x9 box, the 6x6 pseudo tlr, the 35mm slrs, rangefinders, scale-focus and half-frames, the 6x4.5 slr, the 4cmx4cm scale focus, the 24mmx24mm scale focus, the 126 format slrs and all the lenses. Having said that, I have had some of it for over a decade and not around to it, lol.
Perhaps you need to use this lens from a plane or the top of a mountain, or in different lighting conditions to get the best out of it? |

| That’s sort of where I’m at with my stuff. I have alot of gear I like to shoot and after having seen the results being not v more than usual for a Jupiter 8 it got put on a body on the shelf with the collection whilst I have fun with other things. Recently just replaced light seals in my Horizont so that’s what I’m aiming to finish a roll in this weekend :) |

| Ah, I see. Like you and most other members I also have a number of cameras (from 18mmx24mm and 24mmx24mm compacts through slrs, rangefinders, tlr's and 6cmx9cm box) which all work and need to be used. I recently finished using an 18mmx24mm and am using a 24mmx24mm at present, but most of my other cameras have films in ready to use, so now I need to put my shoulder to the wheel, my nose to the grindstone and pull my finger out and get on with it all. |
