A17 ZEISS IKON, Zeiss Ikon IKONTA 523/16, fully functional

Thank you for viewing!

⛵ Real-world test (using 35mm 135 film) revealed overexposure in some photos. Due to the slow shutter speeds, exposure compensation was repeatedly adjusted, resulting in a total of four real-world tests. 【Photos 2-5】explain the exposure compensation process. The photos displayed are scans of negative film. Prints from a camera shop will likely have automatic correction and come out beautifully.

This is a Zeiss Ikon IKONTA Tessar 523/16 spring camera. It's a top-of-the-line model for its time, featuring a premium Tessar lens and a Synchro Compur shutter (B to 1/500), along with a multiple exposure prevention function.
