Used Condition | 35mm SLR Camera | The Ultra-Compact Professional Masterpiece

The Pentax MX is a masterfully engineered 35mm SLR, famously known as the smallest and lightest professional-grade mechanical camera ever produced. Unlike its consumer-oriented siblings, the MX is a fully mechanical instrument, celebrated for its rugged "all-metal" internal construction and its massive, high-magnification viewfinder. Paired with the legendary SMC Pentax-M 50mm f/1.7 lens (S/N: 2933501) from Asahi Opt. Co., this kit offers world-class optical performance in a body that fits in the palm of your hand. With its sophisticated GPD (Gallium Arsenide Phosphide) light meter and precision-balanced shutter, the MX provides the mechanical soul and analog brilliance required for professional street and travel photography.

Key Features

• Ultra-compact all-mechanical body—fires at all speeds without batteries

• Legendary SMC Pentax-M 50mm f/1.7 lens with Super Multi-Coating for superior contrast

• Massive, bright viewfinder with 0.97x magnification (one of the largest ever in an SLR)

• Precision GPD light meter with a 5-LED traffic-light display for rapid exposure checks

• Fully compatible with the extensive Pentax K-mount system

• Professional features including a depth-of-field preview and a self-timer

• "Judas Window" in the viewfinder that allows you to see the aperture setting directly on the lens

Introductory Paragraph The Pentax MX is the definitive choice for the enthusiast who values professional reliability and high-end optics in the smallest possible package. This specific unit (S/N: 4186591) is a standout because it represents the peak of Asahi Optical Co. craftsmanship, where every millimeter of space was utilized to create a precision tool. The SMC Pentax 50mm lens is famous for its "clinical" sharpness and beautiful bokeh, making it an ideal choice for portraits and low-light street scenes. Because it is a fully mechanical camera, it serves as an incredibly reliable companion that will never leave you stranded with a dead battery. Whether you are navigating a bustling city or hiking through the mountains, this Pentax provides the optical brilliance and mechanical heritage that defined the pinnacle of the K-mount era.

Condition Report Used condition. The Pentax camera body (S/N: 4186591) shows visible signs of previous use and cosmetic surface wear consistent with its history and age. The SMC Pentax-M lens (S/N: 2933501) is optically clear; free from fungus, haze, or significant scratches. The shutter has been tested and fires accurately across all speeds. The light meter is responsive, and the LED display in the viewfinder is fully functional. The film advance is smooth, and the aperture blades are clean and snappy.

Specialist Note "The Pentax MX is a marvel of miniaturization. What I love about this model is that it doesn't feel like a 'small' camera when you look through the viewfinder; the view is so large and immersive that it rivals professional bodies twice its size. It’s a rugged, honest piece of Japanese engineering that is widely considered the best mechanical SLR Pentax ever made. The 50mm f/1.7 lens included here is a 'sweet spot' optic—sharper than the f/1.4 version and incredibly compact. For anyone looking for a 'forever' film camera that is a joy to carry every day, even with the honest wear of a used vintage tool, the MX is the gold standard."
