The Sekonic L-458 Digiflash is a hand held exposure meter released in 1984. A similar designed model was also distributed by Bowens as the Flashmeter III.

It is very good design at the time with a easy to use and read digital LCD panel. It is a shutter priority meter, set the ISO and shutter to determine the aperture value. It is capable of measuring ambient light in either a reflective or incident mode. Reflected light requires the REF disc acessory attached to the head, it measure at a 55 degree angle. While the incident require the Lumisphere for 3D subjects or the Lumidisc for flat subjects. Flash measurement is also available by connecting a pc sync cord. The ISO setting is from 3 to 8000 and can be set on the face by pressing and holding ISO button and pressing the up or down keys to change the setting. Shutter speed on the meter maybe a bit limited for some users with speeds of 1/15 to 1/250. A battery check function is available by pressing and holding the On/Off switch, an indicator b.c will appear on the LCD panel with 10 segment level scale, release the button to resume. As a battery saving feature the meter powers down in 5 minutes from the last measurement. After pressing the off button on the power up the meter resets the settings to ISO 64 and 1/60 a sec shutter speed. It is powered by a single 1.5v AA sized battery.
