Equipment Type: Lens
Equipment Brand: Tamron
Equipment Model: Adaptall 105mm f/2.5 - PK, Y/C, M42
Price (S$): $250, $40 neg
Description:
This is a vintage manual focus Tamron Adaptall telephoto lens, the only one made in 105mm and an aperture of f/2.5. Released in 1976, its model designation is CT105 and incorporates Tamron BBAR multiple-layer coating technique to suppress reflections and dispersion on the lens element surface and also renders the best possible colour balance.
Not much information exists for the first generation Adaptall lenses; but enough pictures online to show off the capabilities of this 105mm f/2.5 telephoto lens.
This lens has been with me since the late 90's shooting film, at wide open it is soft in a pleasant way which is nice for portraiture. Stopped down from f4, image sharpens yet retains that same nice softness in out-of-focus area.
Lens is free from fungus, always kept in dry-cabinet when not in use. Some wear marks on the exterior. Ill rate this lens a 9.
I have the following original Adaptall mounts; priced at $40.00 each that works with this Tamron 105mm f/2.5 :
- Pentax PK
- Yashica Contax Y/C and
- M42 thread mount
Some images taken with a similar lens, can be found here (Pentax DSLR) and here (Olympus 4/3 DSLR)

Caveat Emptor - Buyer Beware
My price is negotiable, please understand that I am not a trader and this is from my own collection. Buy only when you are satisfied after inspecting its condition and physical property. I can't offer a refund reason being that it doesn't make sense for me as a seller if you feel the lens does not meet subjective expectations after purchase. Therefore, bring your adaptor/camera, shoot some and decide if this is for you.
Prefer to deal at the following locations: Bedok, Simei, Changi South, Eunos, Lavender
