Incident measurements can be taken with the over 180-degree Lumisphere for general readings of three-dimensional objects, or with the Lumidisc 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. 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.

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) makes 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.

Features

• Instant reading of full range of aperture/shutter combinations
  The analog dial gives you full range of exposure settings for both still and cine applications at a single glance. The analog needle indicates the brightness in foot-candles.

• Amorphous photosensor eliminates need for batteries
  The photocell in this meter generates its own energy to move the analog meter needle. The L-398A is always ready to go. There is no need to change batteries.

• Swivel Head to position incident dome and maintain full view of display
  Easily position the Lumidome for best light reception as you position the meter body for best reading. The swivel head enables “walking the set” to check the evenness of light levels.

• Continuous reading plus needle lock for easy and accurate readings
  Press and hold the measuring button to take continuous readings in varying conditions. Release the measuring button to lock the analog needle in place for exposure calculation.

• Lumidisc for adjusting illumination contrast and measuring illumination intensity
  Take selective area readings or measure several lights for ratios between highlights and shadow areas. Also used for measuring light falling on flat-field objects such as green-screens and artwork.

• Lumigrid for measuring reflected light
  Replace the Lumisphere with the Lumigrid to take reflected light readings of subject areas from the camera position. An optional Slide Set (Direct Reading Slides) enables adjusting the reading meter's reading range for bright subjects.

• Memory pointer retains prior reading
• Just align the pointer with the analog needle to transfer brightness readings to the exposure dial. Once set, a second reading can be made to compare brightness of different lights to adjust light ratios.

• Accessories
  Supplied with Lumisphere, Lumidisc, Lumigrid, High-slide, case and neck cord. Set of 11 direct reading slides sold separately
