  • A and T metering modes for aperture-priority or shutter-priority exposure guidance.
  • 0.66-inch OLED display shows exposure value, compensation, shutter speed, aperture, ISO, battery level and mode.
  • Adjustable cold-shoe position can be moved left, right, centred or inverted to clear nearby camera controls.
  • Built-in 120 mAh battery provides approximately 12 hours of continuous metering.
  • USB-C charging from a 5 V source; the Neto source lists approximately 40 minutes to full charge.
