Accessory wide angle and telephoto lenses for the Pentamatic come in two families. The first are the silver nose fixed YP mount originals (almost certainly all made by Tomioka) released with the Pentamatic and Pentamatic II (Japan only) and the second are the black nose lenses with T mounts in either Pentamatic or M42 released with the Pentamatic S (likely USA only). At least the longer versions are likely to be Tele-Tokinas/Minetars made by Tokyo Koki Co., Ltd., later known as Tokina. The silver noses came in 35mm, 100mm, 135mm, 180mm and 250mm focal lengths, some in a couple of apertures. The black noses came in 35mm, 135mm, 200mm, 300mm and 400mm focal lengths. My website has details and some brochure information but I have pics of all. The lens list has the "Super Yashinon-R 35mm f2.8" in both YP and M42 mounts (the same lens with different T mounts) which are the black noses. There is also an earlier silver nose "Yashica Tominon Super Yashinon-R 35mm f2.8 YP". The lens list has the "Super Yashinon-R Tominon 100mm f2.8" (Yashica wrote it as "Yashica Tominon Super Yashinon-R", not a big thing) in both M42 and YP mounts. The YP is a silver nose from when there were no Yashica M42 lenses. Unless the M42 is a later lens with a retro name, it may be a mistake. There were no black nose 100mm YP versions. The lens list includes the "Super Yashinon-R 135mm f2.8" in both YP and M2. That's correct but there are many more 135mms! Assume that these are the same lens with black nose and a T mount, there is also a silver nose version in fixed YP mount but the same name. Then there is a f3.5 version silver nose and another with black nose and T mount in either YP or M42. The "Super Yashinon-R 180mm f3.5 YP" would be an original silver nose so that's OK. Two "Super Yashinon-R f4.5" lenses are listed in M42, one as "20cm", the other as "200mm". First, I'm not sure why the distinction between "cm" and "mm" for this lens. All the Leica mount and Pentamatic mount lenses I have mentioned so far as well as all the early lenses on the list are marked "cm" on the lens (usually advertised in "mm" by Yashica) but "mm" in the list, specifying it seems a bit odd for one lens? Mistake? Anyway, the "20cm" is a black nose T mount available in YP too. The list contains both a "Yashinon 250mm f4" and a "Super Yashinon-R 250mm f4", both in YP and by length, silver noses. I have never seen a "Yashinon" version but that doesn't mean there isn't one. However, I do doubt it, Yashica started adding "Super" to all its Yashinons with the YE/YF duo. It does appear sans "Super" in the description in one brochure for both 135mm and the 250mm lens but I have seen the evidence of Yashica shorthand elsewhere. Just a comment. The "Super Yashinon-R 300mm f5.6 M42" is a black nose also available in YP. Ditto for "Super Yashinon-R 400 f6.3"

One Pentamatic lens I forgot about is the Yashinon-R f/5.8 90-190mm zoom which is on the list as an M42 lens. I don't have a pic of this one in YP mount but the relevant section of the Yashica US Pentamatic S/Penta J/J-3 brochure makes it quite clear that it was available also in YP and you could even buy adaptors for your Minolta, Nikon, Canon or Exakta SLR!

The 600mm and 800mm were "Yashinon-R" according to Yashica literature.

I borrowed the original list from the first post in this topic to create a spreadsheet for my own use, and asked biggles3 if he would mind me sharing it here. With his kind permission, it's available via Google Sheets as a shareable file. It isn't editable as it is, but please feel free to make a copy or export it to another format you can use and/or edit or add to. Link: Yashica - Draft Lens List
Note, that there are 2 tabs, with the 1st being the list itself, and the 2nd having some very basic notes. I made some minor additions/corrections to the AF lenses, since I had an original insert for some of them - BUT - otherwise it''s pretty much a conversion straight from Graham's original list. It hasn't been sorted, or otherwise modified, but it has had some very minor reorganization and duplicated labeling of column data for sorting purposes, if you wish to do your own manipulations.

I ran across an AUTO YASHINON 3.5cm f2.8 on the Manual Focus Lenses site that dopes not appear to be on this list.
It is half-way down the page.
No details, just a picture.

Hi xkaes
Thank you for the reminder about this lens.
I'm rather embarrassed to admit that my inventory shows that I have one, numbered 3806XX though I can't lay my hands on it. I have moved home 3 times in the last 3 years and quite a few items have gone 'missing', nearly all of which are from my photographic gear. My apologies for the oversight; I have updated the list accordingly.

I've got a similar problem. I just had a new furnace installed in my basement. Sounds simple enough. It all went relatively smoothly, but the only way to gain access to remove the old furnace and install the new one was through my darkroom. I basically had to remove everything in the darkroom. The new furnace is now finished, but I haven't had time to get all the photographic gear back in place -- and I can't find ANYTHING!!!!

Hi, after a long search finally got me an (early?) 35 / 2.8 / m42. it's a dx one. I was surprised to see that is a pre-set version, a "super" one but without "R". It's black with a chrome focusing body and black nose with a very tiny chrome/silver top. Serial stars with #35*****. Anyone an idea .. is this an R version but on m42 mount cause it looks like one, or sth else and is it a real Yashinon or a Tomi or a Spiratone or a Koki or .. whatever else rebranded? Cheers

I'm pretty sure that it's a genuine Yashinon though it will almost certainly have been manufactured on the old Tomioka production line; it's one that has escaped our notice and is missing from the list. Can you take a photo of it and send it to us? Thank you for the information.
As an aside, 2 lovely old Yashica Auto Yashikor lenses - a 28mm and 135mm - have popped up on Ebay today from a German seller; you don't see those old lenses very often - if ever.

From your description, I assume it's like this one... It's not a particularly good looking sample, but I don't see these lenses very often. I think these came out about the same time period as the TL Electro series bodies. There are a few brochure and ad pictures in the Brochures topic showing both the early and late versions, but none seem to mention anything on whether there was such a thing in the wide or 'normal' lens lengths as R versions. The last lineup brochure insert I've seen that still has any presets is this one - and the only R's listed in it are the very long telephotos. I assume this list shows the final round of lenses before all the R's were dropped and the DS-M lenses were introduced... presumably at the end of the M42 lens lines.

Hi and thanx for the respond. It's exactly the same lens like from your pictures. But in much better shape. I'll make pictures and sent it to you. Very good and nice little vintage lens with that 'filmy' feeling. it's reasonably sharp (for such old lens) and the creaminess of DOF is sweet, good contrast, havent spot any CA (yet). Au contraire from ML series that are not quite working for me somehow .. All that on Fuji-X first series.
Already have (as new) auto yashikor 28/2.8 (going to be sold soon), 135 would be just too long for aps-c sensor. super 100 pre-set from the same series is still high on my list. Hope would be good as this little 35 thing.
Thanx again,
Cheers

Hi all, got me (again ..) an (early?) ml 50 1.4 with diamond shaped rubber ring. Serial #1001***. Could this be an old stock of DS/Ds-M just modded to CY mount by Yashica-san? I see a significant dof difference between this one and ml 1.7 one.
and, does Ds 28 (m42) share same optics (not coating!) with ds-b (cy mount) or / and later ml series? I ask because I like old screw Yash's and I have already ds-b/ml in 28 (which both appears to be quite good performers).
Bye

I ask because I like old screw Yash's and I have already ds-b/ml in 28 (which both appears to be quite good performers). Bye Hi alexx,
You can rest assured that your ML 50 1.4 is a genuine ML type; quite a few of the first batches of ML lenses used components from their DSB predecessors - I have quite a few ML 50 1.4 and 1.7 lenses with the silver nose rings and diamond rubbers. Your serial number suggests that you definitely have a first production lens; you should expect to see a real dof difference between any 1.4 and 1.7 lens.
The 28mm lens question is more complicated. The DS 28mm shares the same 8/7 optical formula as the DS-M and DX versions but I've never opened them all up to compare the individual elements and groups. The DSB had a very different optical formula (6/6) and it gets tricky with the ML 28mm as there are two versions - an 8/7 and a 7/6 (I'm not considering the MC 28mm as a true Yashica lens). I can say that the 8/7 ML and DS-M optics look incredibly similar.

alexx ... The early ML lenses had some of the same cosmetic features - if not some of the same barrel parts - as the DSB line. It seems it wasn't uncommon to carry over designs/parts from something earlier, as it probably made economical sense when there's no dimensional differences between families. I have, and have seen, both cosmetic types on everything from the 200mm primes on down to the wides. I don't think there were many changes, if any, to the optical design from the DS/DX/DS-M series to the early DSB versions they became - but - there were some definite differences with both the coatings and the mechanicals, plus the optical elements may have gotten some refinements in glass formulas with the ML line to boost the sharpness and color and CA resistance. The ML's were all multiple nano Anti-Reflective coatings, and not the older single/dual High-Reflection ones. Their optical diagrams likely had to be modified to accommodate the new AR coatings. ( Wiki article on coatings) The 1.7 diagrams are different from the 1.4's, so that would account for DoF differences, whether they're DSB or ML, or any other family line shouldn't matter. [It seems biggles3 has slightly faster fingers than moi :)]
