P67 Field Guide (6x7) / Takumarフィールドガイド(6x7) / PENTAX (67)
Takumar screw-mount enthusiasts.
HOW to use this site: For fast general information go to P67 Field Guide. Frequencies or Summaries on the lens group pages are in preparation. A site for researchers is pentax67.net (Complete SN data for each lens is backed up and available on request.)
SCOPE
Takumar photographic lenses 6x7, 67 (P67) were made by 朝日(Asahi) Optical Company Ltd. in Japan from 1969. They share a serial number sequence with M42 screw mounted lenses; are bayonet mounted and are native to 朝日(Asahi) Pentax 6x7 film cameras.

SCOPE
Takumar photographic lenses 6x7, 67 (P67) were made by 朝日(Asahi) Optical Company Ltd. in Japan from 1969. They share a serial number sequence with M42 screw mounted lenses; are bayonet mounted and are native to 朝日(Asahi) Pentax 6x7 film cameras.
PROGRESS
Takumar Field Guide :
- Numerical results (Summary and Batch data) for M42 lenses are progressively updated. 2017 frequencies for all are complete.
- Qualitative results for Wide, Standard and Long Takumar sections are up to date or developing.
- Summary and Batch data for 6x7 format lenses will be added in 2018. After 1969 6x7 format Takumar and 67 Pentax lenses shared the same SN sequence with M42 Takumars.
- Takumarology contains quirky bits and overviews of interest to collectors of M42.
BACKGROUND
- Takumar is the name Asahi Optical gave its lenses in 1952, initially, those made for its own SLR and early rangefinder (M37x1mm) cameras.
- It honours Takuma Kajiwara (梶原啄磨 Kajiwara Takuma), a Japanese-born portrait painter who lived in USA, whose brother Kumao Kajiware founded Asahi Optical.
- "Takumar" branded M42 screw mount lenses were used on 35mm cameras until 1977 when they were fitted with a bayonet K-mount, more suited to electronic couplings.
- Bayonet mounted Takumars lenses were used on 6x7 Asahi Pentax cameras from 1969 until 1981.
- K-mount lenses were branded "SMC Pentax" but "Takumar" re-appeared, briefly, on K-mount lenses for the final time several years later.
"Takumar Field Guide" will help you study and identify Takumar lenses and their legacy. It describes a collection of lenses (and a few cameras), primarily, and may be useful to researchers and photographers generally. Research for this site is ongoing. The collection of lenses and serial numbers* began in 2010.
