Concava Tessina L

{"overview":"The Concava Tessina is a Swiss-made subminiature twin-lens reflex camera that takes 35mm film loaded into proprietary cassettes, producing small rectangular frames. The Chrome version is the standard factory finish. Condition and completeness of original accessories (cassettes, wrist strap, chain, leather case) are the dominant value drivers today, and clean working examples sit toward the upper end of that band while cosmetically tired bodies anchor the lower end. Buyers searching for what a Tessina Chrome is worth should note the small sample of tracked sales means individual results can move the range noticeably.","buying_guide":"The Tessina is a clockwork-wound precision instrument, so the first check is that the spring motor winds and runs smoothly and that the shutter fires consistently across speeds. Inspect the tiny ground-glass viewing screen and reflex mirror for haze or damage, and confirm the film cassettes are present — they are proprietary and scarce, which materially affects usable value.
