Yashica Lens Club

Hello and hope lot of Pentaxians has one or more of the Yshinons (M42, C/Y) in their dusty part of lens closet. It's time to wipe out the dust and use them on a Pentax DSLR.
Yashinon-DS 50mm f1.9

I hope this thread is still alive when I get home in a few weeks, so I can maybe contribute examples from my Yashica ML 50/1.4 (C/Y), Yashinon DX 50/1.7 (M42), and Yashica DSB 50/1.9 (C/Y). Alas, although I have the planar ML 50/1.4 with me on this trip, my travel mini-laptop hasn't the power to do RAW development in reasonable time. Oh sure, I could shoot some JPG's (grumble, gripe)...

BTW the C/Y to PK adaptation is pretty simple and painless and non-destructive. I've documented that here a few times. Don't avoid C/Y lenses. And does anyone here know if the ML 50/1.4 is Tomioka?

Oh yeah -- nice shots!

Mine is same as the TS.

Has a lot of fungus but when i tried the lens, i don't even care about the fungus anymore

I am now looking for other Yashica lenses that can fit my kx (DS, DX.... but not ML)

Enjoy and hope this thread will encourage all those who are keeping these lenses in their dusty drawers start to dust-off, mount and revive the good old Yashica tradition... if there are any

i forgot to mention that all of the pics were taken wide-open (1.9) since there's no switch to stop-down the aperture....

I tried to open only until the aperture ring was unscrewed but i still can't get to the pin base so i just decided to glue the pin (afraid i would misalign this beauty)...

I went until third layer of screws but chickened out and put them back, hence glued the pin. The position of the aperture ring click ball is quite interesing and different from Helios and Pentax-M I have opened before.

Yashica 35mm F2

Dusted off the old gem. This was at F-5.6 on a K-x.
Colors are the best of my line up but can be soft wide open and sometimes my mirror will hit the back of the lens. Other than that

This is by a Yashinon 45mm 1.8 lens. The lens was on a Yashica Lynx 5000 rangefinder, so if it is not suitable in a Pentax forum, let me know and I will remove it.

Dozen A Dime Yashica ML

After pleasantly surprised with the image quality as well as build quality of ML 50mm f1.7 (recent) and DS 50mm f1.9 (previous), I thought to explore little more of the ML series. As a result acquired two MLs, one ML50/2 and one ML50/1.9c. Even though the IQ of both is good but BQ not, especially 50/1.9c is cheap.
Here is some from the ML 50/2
