Bill, was that Seattle Filworks film the respooled Kodak ECN-2 movie film and you had to send it back to Seattle for processing?

Ian, if you are referring to my images of the lenses, they were made with my Fuji 2mp point and shoot. Lighting was from an offhand electronic flash bounced off a white card. The on camera flash triggered the big flash and caused the specular highlights. The film look was probably a result of a little contrast tweaking.

I have used the Seattle filmworks film in the past but was not impressed with the results.

I'm getting ready to dig out the 50~55mm, f-1.4s for similar group shots. Hopefully the new DSLR and longer lens will result in better pictures.

It should be noted that not all Yashica lenses were made by Tomioka. I've heard the Yashikors were made by Yashica, and the Yashinons were made by Tomioka, but I suspect even some of the Yashinons were made by Yashica (or some other company), because there are so many of them. 2/50, 1.9/50, 1.7/50 1.4/50 1.2/55. The 1.9 is apparently a normal planar whereas the 2.0, 1.7, 1.4 seem to be ultron types or modified ultron types. The 1.9 then is sort of the odd one out.

Mamiya lenses and Yashinons are also different mechanically, the most apparent difference is probably that the diaphragm blades on Mamiya lenses point clockwise, whereas on Yashinons they point counter-clockwise. Except for on the 1.9/50 Yashinon... Confused

My apologies. I was not reading closely enough.

Addenda:

Why is it like that those companies in the same prefecture?
Nagano prefecture is in mountainous country and has cleaner air
to make precision mechanics, that is the main reason. And
this prefecture has the highest education level in Japan, since
feudal age the lords encouraged the population to spend
money for the education, this prefecture cannot produce rice
well (due to high elevation), they had to produce cash crop
such as silk, cloth, and paper (washi=japanese paper).

Cosina: Nakano-shi (northern part of Nagano)
Chinon: Chino-shi
Seiko: Suwa-shi
Tomioka: Shimo_Suwa-shi

The last three area (city) are located in central Nagano prefecture.

Seiko (watch maker) was originally called SUWA-SEIKO-SHA,
which is one of biggest privately owned companies. The Hattori
family has a famous building in Ginza Tokyo with a clock tower
on the top. Seiko still produces shutter for cameras but more
famous for EPSON printers. Oh yes they makes watches too. Very Happy


What an incredibly interesting thread. Thanks for this!
