Real-time Light Metering: The AstrHori AH-M1 light meter can continuously track the changing light values in real-time, It has two metering modes, A and T modes. With known ISO sensitivity and shutter speed, the light meter provides the correct aperture value for proper exposure. Alternatively, with known ISO sensitivity and aperture value, it provides the correct shutter speed for proper exposure, ensuring the intensity of light meets the requirements of the shot. | Full-metal Built, Lightweight and Compact: The AH-M1 light meter from AstrHori is made of full aluminum alloy, with a simple and elegant appearance, high strength, fast heat dissipation, good protection for components, and easy to clean the metal surface. The lightweight design makes it one of the smallest light meters on the market, weighing about 45g. | Adjustable Cold Shoe Position: The cold shoe position is adjustable to be compatible with various old cameras. Using the included L-shaped hex wrench, the cold shoe position can be adjusted to the left, right, center, or inverted to accommodate old cameras with dials or obstacles around the cold shoe. | Long-lasting battery life: Equipped with a built-in 120mAh lithium battery, the AstrHori AH-M1 light meter can continuously measure light for about 12 hours. It uses a USB-Type-C charging port and can be charged with a 5V power source. It takes approximately 40 minutes to fully charge (Tested by computer's USB port). If there is no operation for 10s or 25s, it will enter a low-power sleep state and automatically shut down after about 3 hours of sleep. | OLED Display Screen: Equipped with a 0.66-inch electronic display screen, it shows real-time exposure parameters such as exposure value and exposure compensation, shutter speed, aperture value, ISO, battery level, aperture/shutter priority (A/T), lock icon, and loop mode.

Double energy saving: Continuous metering for 12 hours(Built-in 120mAH lithium battery).Enter the low-power sleep mode after no operation for 25s,and click the button to wake.Automatic shutdown after sleep for about 3 hours.Use a 5V power supply to charge through the USB Type-C interface and it will be fully charged in about 40 minutes(take the USB interface of the computer as an example | Compact and Lightweight:Aluminum body,High quality metal with a weight of 48g,and easy dial operation.The cold shoe mount compatible with various camera,suitable for any model of camera,especially serves well for people who use older Leicas, similar rangefinder cameras,SLR,etc.and also can mesure by hand hold. | High precision:About 30° average metering,single metering time ≤0.5s.Metering range: (ISO100) EV1~EV22;Aperture adjustment range: F1~F32;Shutter time adjustment range: 32s~1/8000s;ISO adjustment range: ISO6400~ISO5;Exposure compensation range: +3EV~-3EV. | A/T Mode Switching:Double-click the button to switch between "A" mode and "T" mode, "A" means Aperture-priority mode. Set the aperture value through the dial.The minimum can be adjusted by 1/3 gear.The light meter calculates the recommended shutter time "T" means shutter time-priority mode.The shutter time can be set by dial.The minimum can be adjusted by 1/3 gear.The light meter calculates the recommended aperture value. | ISO Adjustment and Exposure Compensation Settings :Double-click the key, and press the key for about 0.5s for the second time to switch to ISO adjustment. The minimum adjustment can be 1/3 gear Set ISO through dial. Double-click the key and press the key for about 3.5s for the second time to switch to the exposure compensation setting Set the exposure compensation by dial to change the recommended value calculated by the light meter. The minimum value can be adjusted by 1/3 EV.
