First- and Third-Generation K-mount Pentax Models

   Updated May 3, 2022

    Here is the second part of the fifth entry in our "Choosing a Vintage SLR System" series for manual focus SLRs. In Part #1 we looked at the Pentax M42 screwmount system. Pentax was the last of the "Big 5" (Canon, Minolta, Nikon, and Olympus being the others) to adopt a bayonet-style lensmount, doing so in 1975. The K-mount has continued to serve (in modified form) into the digital era. For now we will confine ourselves to the manual focus film era. So let's get to it with our standard format of: 1) Lenses, 2) Bodies, 3) Flash, 4) Accessories, and 5) Reliability & Servicing.

    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.

    It had been a slow afternoon. The kind of afternoon you read about in cheap detective novels. An empty bottle sat on my desk. As empty as a Maalox bottle could be after two too many Taco Bell chalupas.

    "Why?", I asked myself, knowing full well what the answer would be.

   Fortunately, before I could answer myself, the door swung open. In walked trouble, Nikonista, by the look of the yellow strap hanging out of her handbag with the big, black letters N...i...k...o...n on it. Your learn to pick up on such subtleties after a few years in this business.

The Olympus OM System

   Welcome to the fourth installment of our "Choosing a Vintage SLR System" overviews! It features Olympus, one of the most influential Japanese camera manufacturers. We will work our way through: 1) Lenses, 2) Bodies, 3) Flash, 4) Accessories, and 5) Reliability & Servicing. But first...a little introduction :-).​

​    Olympus first came to prominence in photography in the late 1950s and early '60s with their half-frame (18x24mm, which was half of the 35mm frame) Pen series of cameras specifically targeted at the Japanese and later, the European markets. They were designed to be affordable for the average worker and economical to operate while still providing decent quality for an 8x10 print. Olympus sold millions of Pens. Ironically, it was the refusal of Kodak to support the half-frame format in the USA that pushed Olympus into the 35mm arena. For a more in-depth look at this turn of events, see this article. Although Olympus was the last of the major Japanese manufacturers to get into the 35mm SLR game, they made quite the splash in 1972 when they finally joined the fray. The immense influence Olympus exerted on the photographic world was due, in large part, to the efforts of the brilliant designer Yoshihisa Maitani and his team of engineers. The creator of the Pen and OM series was always seeking to do something different, not just copy others, and this does much to explain the success of Olympus over a three-decade period with its film-based equipment. The OM series would do more to reduce the size and weight of 35mm SLRs than any other system. What is more interesting was the impact this had on the other, more well-established manufacturers (Canon, Minolta, Nikon, & Pentax) known as the "Big 4". By the late-'70s, that designation had to be changed to the "Big 5", due to the success of the OMs. So let's take a closer look at all the OM system has to offer.

    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.
