The Sekonic Studio Deluxe II L-398M is a purely mechanical light meter manufactured in Japan. Originating in the 1970s, it requires no batteries, relying instead on a precision mechanical linkage system to perform light metering calculations. The device supports both incident and reflected light metering and is compatible with both still photography and cinematography (CINE) applications. Its dial integrates scales for ISO, shutter speed, aperture, and EV values, allowing for quick, intuitive reading of exposure parameters—perfect for a wide range of lighting scenarios in film photography. This complete set includes the light meter itself, an original leather protective case, the original box, a lanyard, and a LumiGrid attachment—all of which are authentic, original accessories. The unit shows minor signs of use; the mechanical dials turn smoothly, the needle responds precisely without any sticking, and all markings on the dial remain clear and fully intact.
