Seconic Studio Deluxe lightmeter Model L-28c

The Sekonic Studio Deluxe Model L-28c is a legendary analog light meter produced in Japan between 1964 and 1970. It remains one of the most iconic and reliable tools for classic filmmaking and analog photography.

Battery-free operation: Powered entirely by a selenium photocell. Light exposure generates the micro-current needed to move the needle.

Incident light metering: Measures the light falling on the subject. This provides highly accurate exposures that are not fooled by dark or bright backgrounds.

Swivel head: The measuring head rotates 270 degrees. This allows you to point the sensor at the light source while easily reading the dial.

Needle lock: Features a front button that mechanically locks the needle in place for comfortable reading.

Buying & Maintenance Tips

Because the L-28c is decades old, selenium cells can degrade over time, especially if left exposed to light for years. Always test the meter against a known accurate digital camera or modern light meter to ensure the needle calibration is still correct.
