Analogue light meter. Immediate reading of the entire range of aperture/shutter combinations. Amorphous photo sensor eliminates the need for batteries. Swivelling head to position the incident dome and maintain full view of the display. Continuous reading plus needle lock for easy and accurate readings. Lumidisc for adjusting illumination contrast and measuring illuminance. Memory pointer retains previous reading.

The swivelling head of the Sekonic L-398A allows you to hold down the measurement button and walk through the set to check the lighting conditions. When you release the button, the meter's analogue display pointer locks into place, allowing for easy-to-read exposure calculations. Exposure values are displayed for both still image and film applications.

Precise light measurements in any context. Incident light measurements can be taken with the Lumisphere with an angle of over 180 degrees for general measurements of three-dimensional objects or with the Lumi Selective Area for measurements of the illumination ratio between highlights and shadow areas or the incidence of light on objects with a flat field, such as works of art. The Lumi Selective Area measurement can also be used for measurements outdoors or in bright studio light.

Precise reflectance measurements and quick readings in various shooting situations. For reflected readings, a flat Lumigrid replaces the Lumisphere. If you want to shoot with a fixed ISO value and a fixed shutter speed, you can use an optional slide set (direct reading slides), which facilitates readings in fast shooting situations. The Sekonic L-398A Studio Deluxe III is an ideal main or backup meter for photographers and filmmakers.

Easy to read exposure calculations. The meter has a needle that fixes itself in the analogue display as soon as the exposure button is released. This makes it easy to read the exposure calculations for both photo and film applications.
