L-358 Flash Master


This meter provides a wide range of functions that correspond with most manufacturers camera settings in all formats, which will satisfy professionals as well as serious enthusiasts.

Analysing Function
In this mode, a simultaneous reading of flash and ambient light is analysed. The display shows the percentage of flash in the total exposure, plus f/stop and shutter speed, making mixed light situations simple.

Radio Triggering
Flash units can be remotely triggered with the meter’s optional, internal, multi-channel radio triggering device by pressing the measurement button to take a reading. This feature makes quick assessment of flash ratios simple by eliminating cord connections from meter to flash. (Available as an option).

Direct Display
½ or ⅓ step selectable shutter speeds and apertures correspond with most manufacturers camera settings.

Aperture Priority
Two memory slots are available in both Aperture Priority and Shutter Priority Modes, making contrast evaluation and averaging possible in both modes.

All-Weather Design View Finder
All-weather design 1º, 5ºand 10º View Finders make precise reflected readings for many situations.
