    Tominon Lens Specification

    Looking for Tominon factory spec sheet. These were used on polaroid MP-3 and MP-4 for copy and closeup work. Any info or URL pointers will be appreciated.

    If a pdf is available, please email me through LFPF or email direct to garen@silvercavalier.com

    Thanks.

    If it (they) is found, I'd like to see it, and I'm sure others here would as well.

    You might also try the YASHICA Forum at:

    https://yashica.boards.net

    Although the focus is on Yashica, Tomioka made all of Yashica's lenses, so there are people there knowledgeable about Tominon lenses.

    You could also try

    http://photocornucopia.com/

    The owner has experience with Tominon lenses, and might have spec sheets.

    I have the Tominon 135mm and 75mm lenses and think they are great. Both have 40mm (#1) rear threads.

    P.S. I hope this note is not considered "gratuitous advertising" for these websites.

    Re: Tominon Lens Specification

    That's helpful. Thanks. However, it does not list all of the Tominon lenses. Two that I know of that are not included are the 35mm and 17mm.

    Here is a more complete list of copy & enlarging lenses from Tominon from:

    http://blog.16-9.net/delta-enlarger-lens-archive

    Keep in mind that many of these lenses were also sold under other name brands!

    These are the ones that were sold with the TOMINON label -- that they know of -- note that they do not list the 17mm!

    Re: Tominon Lens Specification

    MP-4 Tominon lens 135 mm 4 elements 3 groups Tessar type
    105 mm, the same
    75 mm, 4/3 reverse Tessar type
    50 mm, "6 group symmetric triplet type" I've never seen a cross-section or found a clearer explanation
    35 mm, 4/3 reverse Tessar type
    17 mm, 6/4 "macro lens"

    OP, these are all for the MP-4. Most of the lenses for the MP-3 are Rodenstock Ysarons, also the 35/4 Eurygon.

    Re: Tominon Lens Specification

    What I found out testing the Polaroid Tominons personally is that the 50mm f/4.5 was actually a process lens optimized for 1:1 (it covers 6x9cm at 1:1). Though Polaroid recommended it for quite different magnification ratios at which the 50mm Tominon was not too good. And Polaroid recommended another Tominon for 1:1 - which was not optimized for 1:1 at all....

    That said, I find my 60mm f/5.6 Schneider Componon sharper then the 50mm f/4.5 Tominon even at 1:1, both for 24x36mm and 6x9cm, though the 60mm Componon is actually optimized closer to infinity. But that Componon is really excellent. It is my reference small format lens for sharpness.

    Ridax, Polaroid's recommended magnification ranges for the MP-4 Tominons are simply the magnifications at which they'll cover 4x5.

    I've had all of them but the 105 and have tried out every one I've had. Quality control wasn't the best, and neither are the lenses. There are better. I wouldn't use the 135 or 75. I'd use the 50 only under duress; a reversed 55 MicroNikkor (any version) is much better. The 35 and 17 aren't best in class but are usable and quite cost effective.

    Re: Tominon Lens Specification

    The old 3.5 version of the 55 Micro Nikkor, reversed - is wonderful for larger than life closeups with 4x5...you can mount a naked shutter in a Nikon rear lens cap and stick this on also - if you need a shutter and/or to sync a flash.

    Yes indeed.

    I like the 127 and the 105 but not the 75. The 75 is worse in its sharpness than the extremely cheap Russian (domestic for me) enlarging Industar 75mm f/4. Worse in the out of focus rendition, too.... A 74mm Wollensak Raptar (which I love; but I can't do anything but admit it's not the sharpest lens in the 75mm Tessar-type pool) is still better. But I concider the 127 and the 105 Tominons to be good (at least the couple of specimens I have/had are). Though even the 127 and the 105 are less good then the Rodenstock Isaron ones of the same focal lengths, made for the same Polaroid cameras.

    I am not a Nikon user but I've tested a 105 Mikro-Nikkor, and it was even sharper than my reference 60mm f/5.6 Componon in the macro range. But the Micro-Nikkor I had an experience with was an AF one with internal focusing, and before it got to my place it had sucked a lot of dust inside it (though I was just the 2nd owner of the lens, and the 1st one didn't use it much) so the Nikkor's contrast was already poor compared to my Componon's.... I've noticed a number of people value MF Micro-Nikkors much more than the AF ones. But again, I am not a Nikon guy, and I don't know anything more about those Mikro-Nikkors of different generations.

    P.S.: I just realized I've typed 135 instead of 127.... corrected it now. Sorry.

    Re: Tominon Lens Specification

    Maybe it's just manufacturing variation, but I'm pleased with my Tominon 135mm and 75mm lenses, but the only comparison I can make are to my Minolta 100mm and 50mm Bellows Macro Rokkor-X lenses.

    And I think the "build quality" of the Tominon's is great.
