Kenko KFM-2100 Exposure meter
The KFM-2100 read flash and ambient lights. For flash reading, the meter has settings for both cord and non-cord triggering.
The large easy-to-read vertical LCD displays F No. values both numerically in 1/10 stop increments with large numbers and in a more common 1/3 stop increments on a vertical scale running up the long side of the LCD.
The KFM-2100 has an integrated spot meter which makes spot readings in both ambient and flash modes easy and fast with no need to stop and add accessories.
The excellent clear-view viewfinder shows F No. read-out in the viewfinder, to read reflected light without having to look away from the scene. The viewfinder has got built in dioptric adjustments.
The KFM-2100 built in with an Exposure navigation system, allowing the professional photographer to easily confirm the exposure for each part of the subject or scene displayed on the LCD to assist in determining the best possible exposure.
The KFM-2100 is seful in mixed flash/ambient lighting situations, the “Analyzer” function of the meter can determine the ratio of ambient to flash light in a scene.
This advance feature is very handy in scenes where a flash is being used to “open up” a shadowed area left by natural (ambient) light.
Latitude Display Function of the KFM-2100 meter for film or digital cameras is useful for scenes with a large brightness difference between light and dark areas.
The KFM-2100 meter’s “Calculation” function can be used to average measurements that have been stored in memory, very useful in reflected light measurements to capture shadow or highlight detail more correctly. The KFM -2100 has the ability to store up to 9 measurements which can be recalled for reference or for averaging.
You just press the “M” button after each reading to store it in the memory. If the memory reaches its maximum (9), it will delete the oldest reading to store the fresh information.
