Our review camera for today is the Zeiss Ikon Ikonta with Tessar 105mm F/3.5 lens and Compur Rapid shutter. This late pre-war folder is quite slim, fits in your back pocket, and takes very sharp pictures with proper technique; whether or not they're good pictures is up to you. This is a 521/2 model, and It takes eight 2¼ x 3¼ (6x9) photos on a roll of 120 film.
This particular model is somewhat odd in that it's a less expensive Ikonta body, but has a four element tessar lens and Compur Rapid shutter normally found on higher end models of the day such as the Super Ikonta. Likely production date for this camera is probably around 1940.
I bought this well used copy from the famed Certo6 for a mere $95 complete with a CLA, and it works great.
With the brief summary out of the way...
