The mid-1970s were a time of major transition in the SLR industry. The biggest changes involved the downsizing of camera bodies (initiated by Olympus), the general electrification and computerization of many functions (most notably with the Canon AE-1), and the inevitable de-contenting and cost-cutting that came with increased competition between all manufacturers for market share. Perhaps no series of SLRs demonstrated being caught in this no-man's land more than the first three models Pentax released with its brand-new K-mount bayonet in 1975. Two models would survive only two years, the third only five. Yet, ironically, the fourth model, introduced in 1976, would go on to be one of the most successful and iconic of all SLRs and would be in production for over 20 years. Fortunately for vintage camera lovers, any of these K-series SLRs can still be enjoyed and are serviceable even today. So let's take a look at the tragic trio of the KM, KX, K2, and the student camera extraordinaire, the K1000.
Domination of the mid-to-late 1960's sales charts. Millions of devoted fans. As influential on SLR development as a certain group of four blokes were on rock 'n' roll during the same period. We can only be talking about one camera...the Pentax Spotmatic (or Spottie to its ardent admirers), the first true superstar SLR.
In their never-ending quest to automate the operation of the SLR, the Japanese manufacturers first targeted auto exposure in the mid-1960s. Auto exposure (AE) initially meant that the photographer had only to set one exposure parameter (shutter speed or aperture) and the camera would automatically set the other. What became known as "shutter priority" (with the user setting the shutter speed and the camera choosing the complementary aperture), was the first AE mode to appear in cameras. It was the easiest to design and could be completely mechanical (no electronic controls) in operation. Konica (one of the smaller and more innovative SLR makers) was the first company to market a practical focal-plane shutter-priority SLR. Nikon began AE research & development in late 1964. It would be five years, though, before they had their first prototype and eight years before they brought an AE-capable SLR to market. So what took so long?
Suffers from a two-decade 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.
