Pushed to this forum from a forum about manual lenses, I thought I should register and see if I can get some hints about my Pentax gear.
As far as my main cams are concerned, I am a Canon shooter.

But I really love my Spotmatic and Spotmatic SPII and I also have two Ricoh KR-10x, one of those was my first SLR ever in 1990.
I really love Asahi Pentax glass (also adapted to my EOS cams).
My Asahi M42 gear:

Asahi SMC Takumar 3.5/35

Asahi Super-Takumar 1.4/50

Asahi Super-Takumar 2.8/105
My Pentax PK gear:

SMC Pentax-M 2.8/28

Pentax-M SMC 1.7/50

Pentax-A 3.5-4.5/28-80 Macro
My othe PK gear:

Hoya HMC 3.5/25-42 Zoom&Macro

Rikenon 3.4-4.5/35-70

Spiratone Plura-Coat 3.8-5.6/28-200 H/D-MC Zoom
