Description
The Mozar Diana is a handsome looking box-type camera from 1950. It is relatively rare. It is made from Bakelite. There is very little information on the web for this camera.
It has two reflecting brilliant finders - one for portrait and one for landscape. It has a red window which has no cover. No carry handle is provided. It has tripod sockets on the base and side for landscape and portrait use. The film is loaded by spliting the front from the back. This is done by simply pulling them apart.
The shutter has two modes - timed(Z) and instant(M). The timed shutter is like bulb(B). The shutter mode is changed by moving a lever on the side. The shutter is fired by pressing a lever, also on the side. The speed of the shutter on this camera was measured as 1/50 sec.
The aperture is changed by moving another lever for f/11 and f/16 .
How to Use
This camera takes 120 film which is easily available.
As the shutter speed is only 1/50s, it is advisable to use a tripod to get clear shake free images. However, holding it against a wall or other solid object would work as well. For quick snapshots, hold it firmly against your body.
If you don't want to bother with an exposure meter, follow the guide shown. It is based on the 'Sunny 16' rule. Film is so forgiving and will produce acceptable results even when overexposed by 2 or 3 stops or underexposed by 1 stop.
The tables assume that the sun is at least 30 degrees above the horizon - that's 10am - 5pm on a summers day (May - August) in the UK.
Remember that the exposure guide in the manual may not be helpful as it is based on the use of old film with a low ISO value.
