OM System OM-3 Astro Mirrorless Camera

OM SYSTEM OM-3 ASTRO Mirrorless Camera (Micro Four Thirds)

The OM SYSTEM OM-3 ASTRO is a purpose-built astrophotography camera designed to capture the night sky with exceptional colour accuracy, fine detail, and creative control. Optimised for nebulae, star fields, and night landscapes, it goes far beyond a standard mirrorless camera—delivering specialist features that make astrophotography more accessible and more rewarding.

Engineered by OM SYSTEM, the OM-3 ASTRO blends advanced computational photography with a compact, weather-sealed body, making it ideal for both remote dark-sky locations and everyday creative use.

Designed for Astrophotography

At the heart of the OM-3 ASTRO is a dedicated IR-cut filter tuned for enhanced Hα sensitivity, allowing it to capture the rich red glow of emission nebulae with greater clarity and contrast straight out of camera. Combined with custom colour profiles optimised for starry skies, it reveals detail that standard cameras often miss.

Ideal for:

• Astrophotography and deep-sky imaging

• Nebulae, galaxies, and star fields

• Nightscapes and long-exposure photography

High-Resolution Night Sky Imaging

The OM-3 ASTRO features High Res Shot technology, combining multiple exposures in-camera to create ultra-detailed high-resolution images with reduced noise—perfect for tripod-based astrophotography or use with tracking mounts.

• Up to 50MP High Res Shot

• Enhanced fine detail and texture

• Reduced noise in low-light scenes

Intelligent Night Photography Features

A suite of advanced computational tools makes shooting the night sky easier and more intuitive:

• Starry Sky AF for precise focus on stars

• Live Composite for controlled long exposures without blown highlights

• Live Bulb & Live Time for real-time exposure monitoring

• Night Vision Mode for easier setup in the dark

These features allow photographers to focus on creativity rather than technical guesswork.

Powerful Imaging Performance

The OM-3 ASTRO is built around a 20.4MP stacked BSI Live MOS sensor paired with the TruePic X processor, delivering fast readout, excellent dynamic range, and high ISO performance—essential for low-light and night photography.

• 20.4MP effective resolution

• Excellent noise control at high ISO

• Fast processing for stills and video

Robust, Compact & Adventure-Ready

Despite its specialist focus, the OM-3 ASTRO remains compact and highly durable.

• IP53-rated dustproof, splashproof, and freezeproof body

• Lightweight premium metal construction

• Ideal for remote locations and harsh environments

At just 413g (body only), it’s easy to carry into the field without sacrificing performance.

Professional Stabilisation & Viewfinding

The camera features 5-axis in-body image stabilisation with up to 7.5 stops of Sync IS, providing stability for handheld shooting and precise framing.

• High-resolution 2.36m-dot OLED EVF

• 3.0" vari-angle touchscreen

• Accurate composition in low-light conditions

Creative Control & Connectivity

The OM-3 ASTRO includes a Creative Dial for instant access to colour profiles, monochrome modes, and creative effects, alongside modern connectivity for streamlined workflows.

• Wi-Fi and Bluetooth

• RAW video data output

• S&Q video modes for slow and quick motion

• USB-C charging and power delivery
