Minolta Auto Meter IV F
Auto Flash Meter
 

 
Equipped with memory, averaging, and monitoring functions, the lightweight and compact Auto Meter IVF measures both flash and ambient light, and includes the important functions to help simplify your most critical applications in photography or cinematography, in the field or in the studio. This easy-to-use meter’s many accessories make it ideal for a wide range of uses.

FEATURES:

Precise and Versatile Operation
A wide range of optional accessories is available for use with the Auto Meter IV F to further expand its applications and versatility.With ambient light or flash, and with or without a sync cord, the Auto Meter IV F is designed to provide unparalleled repeatability and accuracy. In all measuring modes, with reflected or incident readings, it is a meter you can rely on completely, leaving you free to concentrate on the creative challenges at hand.

Large, Easy to Read LCD Display
The LCD display shows all the necessary information at a glance. Shutter speed appears on the left, and aperture on the right. The aperture display is oversized, for easy identification.

Extended Operating Range
Shutter speed range is 1/8000 sec. ?30 min., in 1/2-stop increments. Film speed range is ISO 3-8000, and cine speeds range from 8 to 128 fps. The X-sync range is 1/500 ? 1 sec., in 1/2-stop increments. Both f/numbers and EV numbers are displayed in analog scale, and digitally to 1/10th-stop accuracy.

User-Friendly Controls and Design
The compact and lightweight Auto Meter IV F fits the hand comfortably. Rubber buttons are positioned in a straightforward, easy to use configuration and help keep the meter dust and weather resistant. A rubber-lined frame assures a sure grip while providing additional protection.

2-Channel Memory
The Auto Meter IV F?s memory stores two separate readings and displays them simultaneously, making it easy to determine subject contrast range or lighting ratio.

Averaging of Memorized Data
Calculate and displays the average of two stored measurements. This is useful when basing exposure on highlight and shadow readings.

Brightness Difference Readout
Displays the difference in /-EV, and in 1/10th stops, between two readings. This helps you make quick and precise lighting adjustments.

Flash Reading With or Without a Sync Cord
With a sync cord connected, a press of the measuring button fires the flash and takes an exposure reading. Without a sync cord, pressing the measuring button puts the meter into stand-by mode until the flash is fired manually.

Ambient Light Readings
Simply set the film speed and shutter speed, position the meter, and press the measuring button to take a reading. Hold the measuring button down to take continuous readings throughout the subject area.

Cine Measurements
For cinematographers, the Auto Meter IV F has eight framing rate settings. Plus, the extended ISO range can be used to factor in filtration correction.

Accessories
A wide range of optional accessories is available for use with the Auto Meter IV F to further expand its applications and versatility.
