AstrHori XH-2 Light meter

Precision Light Meter for Analogue and Manual Lens Photography

The AstrHori XH-2 is a compact, precision light meter designed specifically for photographers using analogue cameras and manual lenses. Its robust brass housing combines classic ergonomics with a clear 0.66-inch OLED screen for easy reading in various lighting conditions.

Key Features

• Measurement range: EV1 to EV22 (ISO 100), suitable for very low light to bright daylight
• Supports full exposure parameters: ISO (5–6400), shutter speed (32 s to 1/8000 s), and aperture (f/1 to f/32)
• Exposure compensation of ±3 EV for precise brightness adjustments
• Two operating modes: Aperture priority (A) and Shutter priority (T)
• Average light measurement from a 30° viewing angle, matching a standard 50 mm lens perspective
• Fast single measurement time of ≤ 0.5 seconds
• Compact and slim brass housing with cold shoe mount for stable camera attachment
• Lightweight design (63 g) minimizes obstruction of camera controls and viewfinder
• Built-in 80 mAh battery provides up to 10 hours of continuous operation
• Fast USB-C charging (approx. 30 minutes) with included cable
• Automatic sleep mode after 25 seconds of inactivity and shutdown after 3 hours
• Can be used handheld or mounted on the camera

Precise and Reliable Measurements

The AstrHori XH-2 uses an optical system with a convex lens and graduated light inlet to enhance measurement accuracy and reduce reflections. Its 30° measurement angle corresponds to the field of view of a 50 mm lens, ensuring exposure readings are precise and easily translatable to camera settings. This makes it ideal for use with rangefinders, analogue SLRs, and retro compact cameras.

Operating Modes for Flexible Exposure Control

• A Mode (Aperture Priority): User selects aperture (f/1 to f/32), and the meter calculates the appropriate shutter speed.
• T Mode (Shutter Priority): User sets shutter speed (32 s to 1/8000 s), and the meter indicates the correct aperture.

This flexibility allows quick adaptation to changing lighting without manual exposure calculations.

Ergonomic Design and Durable Construction

The device features a single large dial and one button for intuitive operation, even when wearing gloves. The brass housing ensures durability and wear resistance, while the cold shoe mount provides a secure, stable attachment to the camera without play. Its slim profile prevents obstruction of camera controls or viewfinder.

Power and Portability

The integrated 80 mAh battery supports up to 10 hours of continuous use. The device automatically enters sleep mode after 25 seconds of inactivity and powers off after 3 hours to conserve energy. Charging via USB-C takes approximately 30 minutes, allowing quick turnaround during long shoots or travel.

Versatile Usage

The AstrHori XH-2 is suitable for a wide range of photographic scenarios, from night photography to bright outdoor conditions. Its fast and accurate readings make it ideal for street photographers, filmmakers, and anyone working with manual exposure settings. Exposure compensation enables creative control over brightness and contrast, reducing post-processing effort.
