I'm trying to establish if there is anything different about the Pentamatic Tominon 35mm 2.8 lens and the for instance the Yashica Super Yashinon-R 35mm f2.8 lens.
The latter is 6 groups and 5 elements as described here - https://lens-db.com/yashica-super-yashinon-r-35mm-f28/
Also has anyone been using the Pentamatic mount 35mm on full frame digital? Any examples at all?
When we refer to a Tominon made lens what is special about it? Is it the rarity of the Pentamatic Tominon glass that makes the price so much higher?
Thanks for any answers |

Don't know why Tomioka lenses are inflated or anything related is high-priced.
The Pentamatic is quite rare and due to this, there seems no adapters available for modern camera, or latest mirrorless. I have only got the cusin of the 58mm f/1.7, which is from a Mamiya early SLR and I believe the same lens is on one of the Pentamatic cameras. I have also seen the 5.5cm f/1.8 but didn't grab it due to lack of adapter.
Sorry didn't really address your question, but would like to add something to the Pentamatic related discussion. |

One version of the Yashinon-R 35mm lens is a Sankor lens

It can also be found for much less badged as Accura or Spiratone, among others
( https://www.ebay.com/itm/Accura-35mm-F-2-8-pre-set-wide-angle-lens-for-Nikon-T-mount-provided/362947657854?hash=item54815dc07e:g:R1kAAOSw931ecSuH )
I have one badged Spiratone, that particular copy was not great, and I would imagine the Tominon lens to be better quality. |

I couldn't say for sure, but would imagine the Sankor (Yashinon-R) version to differ optically from the Tominon marked lens, and the other various clones to be more or less identical to the (Sankor) Yashinon-R lens. As I said, the copy I tried seemed overly poor, and wouldn't be surprised if other copies performed better than the one I used.
One difference visible with the 'tominon' marked lens is the deoth of focus marker, as seen here ( https://yashicasailorboy.com/2017/12/07/yashica-tomioka-pentamatic-lens-available-for-purchase/ ) It is quite different to the Sankor version. With this visible difference, and the different manufacturer identifications, my impression would be that they are two different computations.
edit - the accura and mamiya lenses you have linked to both look to be Tokina made. |

Tomioka lenses have to be the most over-hyped, it is a total myth they are any better than other cheap Japanese 3rd party lenses of the same period.
Two of the lenses in that list of four on ebay are Sankors - the ones with E after the serial number.
All you are looking at with those cheap Japanese 35s from that time frame is a tessar 4e/3g lens with an extra large, highly curved element added in front. Most of them are mediocre.
There is one lens of that type (tessar with extra large front element) that I would highly recommend and that is the Meyer Primagon. It is a whole different level of quality to those cheap Japanese versions which most likely coped the Primagon. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

Form japanese photoindustry history it is clear that yashica merged with Tomioka and if "tomixxx" on a lens signifies origin in tomiokas workshops, I would assume that the two lenses might be similar. But, given the tendency to keep names while changing designs, they might be just as different as the early and later Sonnars. And in contrast to mr. Berteles creations, the original calculation and assembly might not have been particularly good.

So is there any reason why the Pentamatic fit Yashica Tominon Super Yashinon-R 3.5cm f2.8 sells for such high prices?
I'm also surprised why there are so very few images out there from this lens available to see.
Anyone have one of these? |

I did post a link to my pictures tagged for the this lens.... Unless I am mistaken about what you wrote.
The beautiful build is icing on the cake, it's one of my most preferred portrait lenses, people seem so lifelike you could reach out and touch them, so, yeah if the body wasn't as wonderful I'd still love it for the optics. _________________ A Manual Focus Junky...

Your shots are quite lovely.
The peaches are beautifully rendered and the amount of detail in the cliff face is extraordinary.
I searched for some portraits but could not find any.
Well done for the images that you have posted

Nobody honored German patents after World War II. One of the reparations was invalidating all their patents. Thus Japanese lens makers could use Zeiss' hard coatings -- but Leica couldn't, because the patents were still in force in Germany. |

I have this lens too but named Super Yash-DX
so R gone - add DX
and with DX is of course M42 mount
Some time ago I was trying to figure out is this just re-badged old Penta mount ("tomioka") or something else ..
Great performer, had at that moment a Nokton to compare .. |

Interesting, I've not seen that lens before, I've done a few searches for presets but never seen it, not that my searches are exhaustive since my searches rely on "preset" being used on the page.
If anyone knows of a preset database I'd love to hear of it. _________________ A Manual Focus Junky...

I had a Yashinon-R copy arrive in the last few days, this copy was actually half decent, good (ish) corners at F8 and infinity, reasonable IQ across the frame. Competitve for that era, certainly. Perhaps my spiratone copy is defective, suffered from reduced emphasis on QA, or perhaps Spiratone/Accura took the seconds? Who knows... |
