3d model perfekta ii vintage camera - Perfekta II Camera by BlueGreen

The Perfekta 1 had a flip-up frame finder, an aperture controlled by a small knob below the lens, and a B/I shutter control on the side of the lens barrel. The shutter-release was a button below the lens, opposite the aperture knob. The design is very much like the Druopta Efekta, except for the placement of the shutter control and release.
The more rounded Perfekta II and Perfekta P66 (c.1956) had a collapsible lens barrel, an optical finder and a ring around the lens to control shutter speed. The shutter-release was moved to the top of the body.
