Here’s the Zeiss Ikon Tenax I, possibly the cutest camera in the world!! If you’re a cutie of whatever species
or gender out there, you’re going to love this camera!! It will match you!!
The Zeiss Ikon Tenax I is a tiny, mechanical, scale focus camera with a reverse Galilean collapsable viewfinder, and square format 24×24 on 35mm. Commercial automated scanners are confused by this and won’t scan these negatives correctly. For these negatives, it’s best if you have your own scanner. Custom scanning is too evpensive. It cost me US$53 + tax to get the roll for the gallery scanned. This was after the photo children at the CVS Photo Kiosk tried to scan them, then crashed their Noritsu twice, screamed naughty things in Armenian, and one of them kicked the machine several times (riot grrrrls every one and the managing gnome was away at lunch). I would not go to a sporting event with any of them, and I’m buying my own scanner, soon.
Anyway, the data:
Size: tiny, fits in your coat pocket.
Weight: much heavier than it looks.
Material: metal, glass, and leather.
Viewfinder: folding, reverse Galilean.
Shutter: Compur, 1 – 1/500 + B (very accurate), no flash sync.
Lens: Carl Zeiss Jena Tessar F = 3 3/4cm (intensely sharp, excellent contrast).
Aperture: f/3.5 to f/22, no click stops.
Focus: by scale, 0.9m to infinity.
Format: 24×24 square negative, 48-50 exposures on a roll of 135-36.
Vintage: East Germany, possibly 1952-1953 (I’m guessing).
Service life: probably forever.
I bought this camera with a clean leather case at an estate sale in South Pasadena, California for US$30, very clean looking, but with a sticky shutter. I got it CLA’ed at Camera Max for US$45. It now works perfectly. Harry at Camera Max says that Tenax I’s were made for a long time and are fairly common at estate sales, especially in Europe. Watch for one to buy. A Tenax I is the way to go for economical square photos.
