Medium Format Cameras & Light Meters

We were introduced to some new equipment for use on the latest mini assignment. Firstly was the medium format film camera.

We were shown around 2 models both by Mamiya.

RB67

The Mamiya RB67 medium format camera was first introduced in 1970 and gained instant acclaim for is distinctive use of a 6x7cm format as opposed to a 6×6 system employed by its rivals. This setup created a clear distinction between landscape and portrait which the camera skilfully handles with its unique rotating back feature. As with all medium format cameras of its time it is solidly built and nothing like as portable as todays modern DSLR devices. When used correctly the RB67 produces outstanding quality and detail and became a common sight in professional studios around the globe.

The second camera was a Mamiya 7, first introduced in 1995 it is by comparrison the the RB67 both light weight and portable and hirano-mamiya7-5-530x504also capable of producing 6×7 cm negatives for outstanding quality and detail. The Mamiya 7 uses a built in range finder but required a hot shoe adapter as I elected to use a wide angle 50mm lens.

There are two ways to meter the light, the first is an incident meter reading which is more commonly used in studio work and the second is the reflective reading. The reflective was more pertinent to the work we were doing as it returns the ambient light reflected from your area of focus. Once the mode is set to ambient light you set the ISO to match your film speed, then your preferred shutter speed, before directing the light meter with the plastic dome slid away from the sensor towards your target and press the large button on the side. The meter will return a suggested aperture required for a good exposure. If the aperture is outside the limits of your lens you can then adjust the shutter speed and the aperture will change to suit.
