Description
The Coronet Dynamic 12 is a quirky viewfinder roll-film camera made of Bakelite by Coronet in England. It is similar to the Coronet Popular Twelve Camera. The use of Bakelite allowed the designers' imagination to run wild, resulting in a most individual camera in which the curvilinear nature of the film compartment is juxtaposed to the box nature of the lens compartment and viewfinder. The camera can use both 120 and 620 film rolls and produces twelve 6 x 6 cm exposures. It has a large brilliant viewfinder, ever-set leaf shutter and a silent winding key. The viewfinder has a ribbed metal cover.
This camera only has instantaneous shutter mode. The shutter release is below the lens box and it has to be pushed up to trigger it. This is both inconvenient and uncomfortable. Film advance is by a knob on the side and exposures are counted using a red window which has a swinging metal cover. It does not have a tripod mount. The back is held on with press-studs.
How to Use
This camera takes 120 film which is easily available. It supports instant(I) mode only with a speed of about 1/30 sec. It has a single aperture settings of f/16. With a shutter speed of only 1/30 sec, make sure you brace the camera against your body or something solid and press the shutter smoothly to avoid camera shake.
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 over-exposed by 2 or 3 stops or under-exposed by 1 stop.
The table also assumes that the sun is at least 30 degrees above the horizon - that's 10am - 5pm on a summers day 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.
So, on a nice sunny day, it's simplicity itself. Just load film and snap away.
