Zeiss Ikon Tenax I (570/27)
The Zeiss Ikon Tenax I (570/27) is a 35mm viewfinder camera that produces 24×24mm square negatives on standard 35mm film. It was a compact, fixed-lens model positioned in the lower-to-middle tier of Zeiss Ikon's pre- and post-war 35mm range.
Sales data for the Tenax I is extremely thin: a single recorded UK auction hammer result from 2003 saw an example sell for £178. With only one historic data point and no recent comparables, today's value is difficult to estimate reliably, and any current price would depend heavily on cosmetic condition, shutter function and completeness.
Sales History
Prices shown are realised prices — auction results and completed eBay sales, never asking prices. Most saleroom figures are hammer prices, before commission; some houses publish a premium-inclusive figure, and we do not adjust for condition. Dealer and retail asking prices are typically higher.

Frequently asked questions
What is a Zeiss Ikon Tenax I (570/27) worth today?
The only recorded UK auction sale in our data is a £178 hammer price from 2003, so a confident current value cannot be given without more recent comparable results.
How much does a Zeiss Ikon Tenax I sell for at auction?
With just one historic hammer result of £178 on file, the Tenax I has too little recent sales evidence to quote a reliable price range.
Why is the Tenax I's market value uncertain?
Auction appearances in our dataset are rare, and a single sale from 2003 is not sufficient to establish a current market value or a meaningful price range.
