The Franke & Heidecke - Braunschweig lenses have a Heldoscop-Anastigmat 1:3, 1 f=7.5cm upper and Carl Zeiss Jena Nr. 1901677 Tessar 1:3,5 f=7,5cm lowered lens((which seems to have a small scratch in the center as well as a bubble in the glass lense. Both lenses are a little hazy inside.

The leather strap is broken but everything else seems to work freely but The brand, Rolleiflex, is highly regarded in the photography industry for producing exceptional quality cameras. This particular model is a great find for collectors and photographers alike, with its classic design and historical significance.

This is a Rolleiflex Standard K2 Twin Lens Reflex medium format camera, built by Franke & Heidecke Brunswick between the years 1932 and 1938. This model was the first revision to the original Rolleiflex from 1929 and upgraded the camera with several significant features, including support for 120 format roll film instead of 117 roll film, a film rewind crank, sports finder, removable back, exposure counter, support for 35mm film, and an optional f/3.5 Tessar and Compur-Rapid shutter. The very next model that replaced it was also called the Standard, so as a result, has earned the nickname as the “Old Standard” although that never appeared in any promotional material at the time. It was the first camera made by Franke & Heidecke to garner worldwide attention and set the standard for what a Twin Lens Reflex camera should be.
