MINOX C spy camera with its subminiature case and measuring chain, which is an interesting combination of items often associated with the MINOX C camera. The MINOX C was a very compact and discreet camera, designed for covert photography, and it came with several accessories that made it more versatile for professional or clandestine use. Let me break down what each item means. MINOX C Spy Camera. Camera Type: Subminiature film camera (8mm x 11mm film format). Lens: Typically equipped with a 3.5/15mm lens (f/3.5 aperture, 15mm focal length). Usage: It was primarily used for espionage or secretive photography, given its tiny size and portability. The MINOX C came with a leather or synthetic case that was designed to protect the small camera while also allowing for discreet carrying. The case often had a small, snug fit for the camera, and sometimes it included compartments for accessories like film spools or the measuring chain. Purpose: Besides protecting the camera, the case was also a way to carry the camera unobtrusively, often in a pocket or under a jacket. Condition: Since you mentioned “excellent condition, ” if the case is in good shape, that adds significant value to the set, especially since these cases are prone to wear over time. Measuring Chain (often known as a “Measuring Tape” or “Rangefinder Chain”). Purpose: The measuring chain (or rangefinder chain) was an accessory designed to assist with focusing. It allowed users to measure distances directly, which was helpful since the MINOX C had a manual focus system without any built-in automated features for distance estimation. The chain is a thin metal cord or chain that was typically marked with specific distance increments. You could use it to measure a subject’s distance, and then you could adjust the lens focus ring accordingly. Usage in Photography: The chain was essential for more accurate and efficient focusing, especially in situations where precise focus was needed but the camera’s small viewfinder and lack of an autofocus system made it difficult. Condition: If the measuring chain is intact, undamaged, and still functional (with no rust or significant wear), it can be a rare and valuable accessory for collectors or users of vintage MINOX cameras. The MINOX C camera set, with both the subminiature case and measuring chain, is typically sought after by collectors due to its historical significance and the fact that all these components together are relatively rare today. The measuring chain is a relatively unique accessory, and finding one in good condition (especially if it still has the correct length and markings) can increase the overall value of the camera kit. If the camera and accessories are in excellent condition, with minimal wear on the case and chain, it could significantly increase the value for collectors or those interested in using the camera for vintage espionage-style photography.
