Description

The Coronet Rex Box camera uses rollfilm No.120. It is similar to other cameras made by Coronet and in particular the Coronet Ambassador. These cameras were also made by Tiranty in France. This means that the same camera model could be found either British made or French made. The Rex is a simple box camera designed for capturing 6 x 9 cm pictures. It is constructed in two parts. The front is made from ribbed Bakelite with a decorative metal front plate. The rear is a metal box. It features chrome hinged view finder covers over two brilliant finders for landscape or portrait photos. It has a nice ribbed plastic strap.

It has a fixed focus meniscus lens. The film plane is curved to give better focus at the corners. Shutter has two settings: instant or time, although the time setting is more like 'bulb'. There is a tab to pull to switch between instant and time exposures. The film advance is not coupled to the shutter release so double exposure is possible. A built in green filter can be pulled into place by a lever on the side. The green filter can be used for photographing plants, separating the green foliage from the brightly-coloured flowers. It can also be used in landscape photography to boost the appearance of grass and trees. This model has synchronised flash connectors on the side.

How to Use

This camera takes 120 film which is easily available.

As the shutter speed is only 1/45s, 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.
