The camera uses a reflex viewfinder. The bright circle in upper right corner is the viewfinder
lens which is illuminated by the mirror behind it by my flash. There's another lens with a
bubble level in it which can be seen in photos on either side of this one. The camera
is held at waist level. The small dial at the top center sets the shutter speed.
The lever at about 2 o'clock (just below and to the left of the bright circle)
cocks the shutter. The shutter itself is located at 8 o'clock. The tiny dial
just above the shutter sets the shutter mode (Z = time exposure, B = bulb,
M = instant). The camera uses 120 film.
