Concava Tessina 35

{"overview":"The Concava Tessina 35 is a Swiss subminiature camera that uses 35mm film loaded into proprietary cassettes, producing small rectangular negatives in a twin-lens reflex layout. These are UK auction hammer results — wholesale levels rather than retail asking prices — so dealer and specialist prices for comparable examples tend to sit higher.","buying_guide":"Inspect the small spring-driven motor for smooth wind-on across the full frame count, check the twin lenses and viewing prism for fungus or haze, and confirm the shutter fires consistently at its slow and fast speeds. The proprietary 35mm cassettes are essential for use, so their presence (and ideally a spare) adds value, as do the original chain, wrist strap, prism or meter accessories.
