This is a so-called Focus Free or Toy Camera, a simple plastic camera.
THIS ONE is quite common and there seem to be lots of cameras under the
Protax name, slightly different in style and in various colours.
Its
main features are:
wide
angle plastic lens, focus free
Shutter
~ 1/100
Double Exposure Prevention, flash, lens protection slider
Size 113 x 74 x 44, Weight 132 gr.
Camera with strap, German instructions.
Camera front closed.
Camera open. Flash on switch under the flash.
Camera back. Battery compartment.
Takes one AA battery. Viewer, film advance and film type window,
not so common on these cameras.
Camera top. Rewind, flash ready lamp, shutter release.
Camera bottom. Film counter, rewind release.
These
are
the ultimate basics of a camera, focus free, single shutter speed and
fixed aperture. Point and shoot only. If you choose the right film, ISO
400 in general and ISO 200 on very sunny days, you can shoot outside
photos that look OK. The rest will be "Lomo" style, but you can use flash for interior
photos.
