The Sekonic L-398A's swivel head allows you to hold down the metering button and "walk the set" to check light levels. Release the button, and the needle locks down the meter's analog display needle for easy-to-read exposure calculations. Exposures are displayed for both still and cine applications.

Incident measurements can be taken with the over 180-degree Lumisphere for general readings of three-dimensional objects, or with the Lumi selective area readings, measuring the lighting ratios between highlights and shadow areas or light falling on flat-field objects such as artwork, measurements outdoors or under bright studio lights.

For reflected readings, a flat Lumigrid replaces the Lumisphere. If you plan on shooting with a fixed ISO and shutter speed, an optional Slide Set (Direct Reading Slides) that make it easier to take readings in fast-paced shooting scenarios. The Sekonic L-398A Studio Deluxe III makes an ideal prime or back-up meter for still or motion picture shooters.
