The Welta Perfekta is a rather rare twin-lens reflex (TLR) with a rather unusual design. It is small and designed like a folding camera, with a bellows. But it unfolds and folds in the blink of an eye thanks to an ingenious mechanism. Its 12 frames are 6 x 6 cm, just like the first Rolleiflex released 5 years earlier. It weighs 994 gr.
The camera was available in two versions: with the Tessar, as shown here, or with the Trioplan. See the other presentation Perfekta Trioplan
