Pentax 12621

Quick view

The 12621, part of the Pentax MX series, is a 35mm single-lens reflex (SLR) camera introduced in 1976. It features a compact and lightweight body with manual exposure control and interchangeable lenses using the Pentax K-mount, supporting precision and versatility in photography. The camera is equipped with a through-the-lens (TTL) metering system for accurate exposure readings. Its shutter is mechanically controlled with speeds ranging from 1 second to 1/1000 of a second. The MX includes a concise and clear viewfinder with approximately 92% frame coverage and magnification of 0.87x, enhancing user composition. This model operates without batteries for shutter control, ensuring reliability in various conditions.

The Pentax 12621 excels with its robust mechanical shutter, enabling operation without battery power, which ensures functionality in remote or challenging environments. Its compact and lightweight design offers excellent portability compared to other SLRs of the era. The TTL metering system enhances exposure accuracy, critical for professional and enthusiast photographers. Compatibility with Pentax K-mount lenses provides users a broad range of lens options. The intuitive manual controls give photographers full creative control over exposure settings. Additionally, its durable construction offers longevity and dependability.

One limitation of the 12621 is the absence of automatic exposure modes, requiring manual adjustment which can be challenging for beginners. The viewfinder covers approximately 92% of the actual image frame, which might result in slight framing discrepancies. The lack of built-in motor drive means film advancing is manual, potentially slowing down shooting speed. It does not feature modern conveniences such as autofocus or electronic shutter control. The camera also requires an external flash system for low-light photography. Lastly, the model has limited ISO sensitivity options dictated by the film used, which restricts flexibility in different lighting conditions.
