The Minolta Flash Meter series was started in 1969 with a light meter bearing the same name.

Flash Meter
The Minolta Flash Meter was an analog measuring instrument with a color-corrected silicon photo cell as light sensor. This element was developed and produced by Minolta itself, as well as the whole flash meter. The meter needs one AA-battery and five PX625 batteries. The analog instrument's scale changes when the ASA-preselector on the meter's top is re-adjusted. Then the EV-value scale stays, but the scale of corresponding apertures is shifted right or left. When the right ASA film speed value appears over the scales the measuring can be done. The meter's front side shows the instrument and the preselector for the shutter speed. The instrument's needle shows an approriate aperture value for the preselected film an shutter speeds. Therefore the big metal button on the meter's side must be pressed down. Then the needle shows the EV of the moment of pressing down the button. On the bottom are two connectors, one for a remote sensor and one for a flash firing cable. When a flashgun is connected the meter can be used in a dark room. When its big button is pressed the flash is triggered synchronized to the moment of measuring. The instrument's needle keeps staying over the measuring value as long as the button is pressed, and a little lamp over the scale makes it readable in the darkness until the button is released. Another small button serves for the battery check. The sensor is located behind a round hole in the meter's back. The hole is a screw mount for the diffusor. One of several different diffusors can be chosen.

Flash Meter II
In 1976 the series was continued with the Minolta Flash Meter II which had an LED display instead of an analog instrument scale.

Flash Meter III
In 1980 the Minolta Flash meter III followed. It had a more versatile LCD display and a built-in digital micro-controller.

The flash meter was further developed with the appeareance of the Flash Meter V in 1995. This version of the meter features a sliding lid. When slid upwards the mode, memory, S/A/H and difference buttons are shown. Slide it down it reveals the ISO button and dedicated instant film ISO override button. A tripod socket is also provided. The meter is also compatible with most of the accessories from the previous Flash Meter III and above.
There are four dip switch settings in the battery compartment to customize the meter. This included switching between photo or cine mode; EV of F. no mode; 1 stop or half stop shutter mode and a mode to turn on or off the tone when measuring flash in wireless mode. An calibration adjustment can also be made from -0.08 to +0.07, this is useful when using multiple meters.
Flash Meter VI
The Flash Meter VI became available in 2003. It was Minoltas last photographic meter, before they merged with Konica. After Sony took over, they sold the manufacturing to Kenko. It then became available as the model KFM-2100.
