Key Features

• Universal M42 screw lens mount architecture, unlocking compatibility with hundreds of historic vintage lenses from Pentax, Yashica, and Carl Zeiss.

• Fast Cosinon 50mm f/1.8 standard prime lens, offering outstanding optical sharpness, high contrast, and flattering subject isolation.

• Reliable mechanical focal-plane shutter mechanism, firing completely independently of battery power across all speeds up to 1/1000s.

• Simple TTL match-LED exposure metering, using bright red and green light indicators inside the viewfinder for effortless exposure balancing.

• Multi-coated internal anti-reflection lens elements, minimizing flare and ghosting artifacts while maintaining natural color rendering.

• Intuitively placed mechanical depth-of-field preview lever, allowing instant physical assessment of your focal plane before exposure.

• Precision ground-glass split-image focusing screen, enabling fast, tack-sharp manual focus confirmation under any lighting conditions.

Condition Report Good condition. Body: Shows normal signs of light use, including minor cosmetic surface scuffs on the top plate and light edge wear on the baseplate consistent with careful handling. The leatherette wrap is completely intact, and the film chamber is clean with fresh light seals installed. Sensor/Optics: The reflex mirror and internal pentaprism viewfinder are bright and clear. The attached 50mm lens elements are completely free from internal fungus, heavy haze, separation, or deep glass scratches. Minimal internal micro-dust is visible under inspection light, which is typical for a vintage lens and does not affect images. Mechanics/Electronics: Fully operational. The mechanical shutter fires accurately across all speeds from 1s to 1/1000s, the film advance lever operates smoothly, and the built-in exposure meter reacts instantly to changing light conditions.

Specialist Note "The Cosina CSM is widely celebrated as an exceptional, rock-solid alternative to more expensive M42 mount cameras like the Spotmatic. What makes this specific kit a standout choice is its pure mechanical reliability—the battery only runs the internal light meter, meaning the camera itself will never leave you stranded in the field. The included 50mm f/1.8 Cosinon lens is a gorgeous performer that renders skin tones with a soft, vintage warmth while keeping details beautifully crisp in the center. Because it uses the universal M42 mount, it serves as the perfect affordable gateway to exploring an infinite world of historic analog glass. It is a completely transparent, satisfying tool that makes manual photography incredibly rewarding."
