PENTAX SUPER A

Name: Pentax Super A
Brand: Pentax

The Pentax Super A is a 35mm film single-lens reflex (SLR) camera introduced in 1983 as part of Pentax’s advanced A-series lineup. It combines manual control with emerging automation technologies, offering aperture-priority autoexposure and a pioneering program exposure mode, making it one of the most sophisticated Pentax SLRs of its era.

Overview

Released in late 1983, the Pentax Super A (known as the Super Program in North America and Program A in Japan) represented the technological peak of Pentax’s manual-focus 35mm SLR development before the advent of autofocus systems. Positioned above the Pentax A3000 and A3000N, the Super A targeted serious amateur and semi-professional photographers seeking a balance between creative control and automated convenience. It was the final evolution of the long-running Pentax K-series mechanical SLR lineage, incorporating a microprocessor-controlled exposure system while retaining compatibility with the extensive Pentax K-mount lens ecosystem.

The Super A introduced Pentax’s first program exposure mode, which automatically selected both shutter speed and aperture based on scene luminance and user-selected film speed. This innovation marked a significant shift toward automation in Pentax’s design philosophy, aligning it with contemporaries like the Minolta X-700 and Canon AE-1 Program. The camera featured a comprehensive LCD display in the viewfinder and along the top deck, providing real-time exposure data, shutter speed, aperture, and flash readiness. Despite its advanced electronics, the Super A maintained a robust metal chassis and mechanical shutter backup, allowing operation at 1/100 sec without batteries—critical for reliability in field conditions.

Historical Context

The Pentax Super A was launched during a pivotal period in SLR development, as manufacturers raced to integrate microelectronics into consumer cameras. The early 1980s saw a transition from fully mechanical systems to computerized exposure control, driven by Japanese innovation. The Super A directly competed with the Minolta X-700 (1981), which had set a new benchmark for programmable SLRs, and the Canon AE-1 Program (1981), which combined automation with a sleek design and marketing appeal. Pentax’s response was the Super A—a technically refined camera that emphasized reliability and compatibility with existing lenses.

Despite its advanced features, the Super A had a relatively short production run (1983–1985), likely due to the rapid emergence of autofocus SLRs like the Minolta Maxxum 7000 (1985), which rendered manual-focus programmable cameras less competitive. Nevertheless, the Super A was well-received for its intuitive interface, robust build, and seamless integration of automation without sacrificing manual override options. It served as a bridge between traditional SLR design and the electronic future, maintaining Pentax’s reputation for engineering excellence.

Collectibility & Value

Today, the Pentax Super A is regarded as a collectible example of late-era manual-focus SLR technology. While not as rare as some limited-production models, its short production span and advanced feature set make it desirable among vintage camera enthusiasts. In excellent working condition, the Super A typically sells for $100–$180 USD, with higher prices for units with clean LCDs, responsive shutters, and original accessories.

When purchasing a Super A, collectors should verify the functionality of the shutter across all speeds, the clarity of the LCD displays (prone to fading or "ghosting" over time), and the operation of the exposure meter. The camera uses two 1.5V SR44 or LR44 batteries (or one 3V DL/CR-1/3N) to power the meter and electronics—battery leakage is a common issue in stored units and can damage the circuitry. Additionally, the rubber grips and light seals should be inspected and replaced if deteriorated. Due to its microprocessor dependency, full functionality requires fresh batteries and a properly calibrated meter.

Repair & Maintenance

The Pentax Super A operates on two 1.5V SR44 (or equivalent LR44) button-cell batteries, stacked to provide 3V for the metering and exposure systems. Some users substitute a single 3V CR-1/3N battery using an adapter, though voltage compatibility should be verified to avoid metering errors. Common issues include degraded LCD displays, sticky shutter curtains at slow speeds, and oxidation on battery contacts. The microprocessor and shutter mechanism are sealed units, making internal repairs complex and best left to experienced technicians.

Routine maintenance includes cleaning the mirror and focusing screen, checking the light seals (which often degrade into a sticky residue), and ensuring the film advance and rewind mechanisms operate smoothly. The camera’s mechanical 1/100 sec backup is a valuable failsafe but should be tested periodically. Given its age, preventive servicing is recommended for regular use, especially if the camera has been in long-term storage. Replacement parts are limited but available through specialty vintage camera repair shops and donor units.
