For film photographers using large format cameras, the Digital Focal Plane Meter from CatLABS provides precise exposure control by metering along the focal plane. Handy and battery-operated, it slides right into where the film holder goes, allowing metering at any point in the image. It's especially useful for zone system enthusiasts, as the sensor is fine-tuned for visible light with a 540 nm peak sensitivity.

Its digital display is clear and adjustable and also offers a bar-graph for negative intensity. The system covers a wide shutter speed range, from 1/4000 second to 1 hour, and supports film speeds from ISO 1 to ISO 8000 in 1/3 stop increments. A unique "hold" function allows users to maintain up to two separate point readings while considering a third. The unit comes with a frame compatible with 4x5 systems, while a larger frame for 8x10 systems is available separately.
