Greetings, and welcome to our fifth vintage SLR system overview, this time featuring Pentax (or Asahi Optical Co. as they were originally known). In this installment we will examine their first SLR system, which (aside from the Asahiflex models) utilized the M42 screwmount introduced by Zeiss in 1949. Over time, such was their success, M42 became commonly referred to as the Pentax screwmount. The M42 mount was used by Pentax for 20 years (1957-76) and today represents one of the most affordable and accessible SLR systems available to the vintage-focused photographer. In the second part of our Pentax overview, we will dig into the bayonet-style K-mount system introduced in 1975, and which is still used (in a modernized electronic form) by Pentax. As usual, we will break things down by: 1) Lenses, 2) Bodies, 3) Flash, 4) Accessories, 5) Reliability & Servicing.
Suffers from a quarter-century and counting film and manual focus SLR addiction. Has recently expanded into 1980's AF point and shoots, and (gack!) '90s SLRs. He even mixes in some digital. Definitely a sick man.
