The Coronet Flashmaster is a viewfinder rollfilm camera made of Bakelite by Coronet in England. Its film roll holders were attached to the removable metal back. The back had also a red window. The camera uses 120 film rolls. On the top it has an optical viewfinder. It has an aluminium film winder. There are several Coronet cameras with the same shape.

It has instantaneous mode only with a shutter speed of about 1/40 second. It has a fixed aperture of f/14. It is capable of capturing twelve 2¼ inch square (6 x 6 cm) exposures on number 120 roll film.

It features a shutter lock to protect against accidental shutter action.

The shutter is synchronised for use with the Coro-Flash Synchro Gun. There are two flash terminals on the side.

How to Use

This camera takes 120 film which is easily available. It supports Instant mode with a speed of about 1/35 sec. It has a single aperture settings of f/14. With a shutter speed of only 1/35 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 shown assumes the shutter speed is about 1/35s.

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.
