OM SYSTEM has announced its new OM-3 ASTRO Mirrorless Camera, which is essentially an astrophotography-optimized version of its existing OM-3 Mirrorless Camera Micro Four Thirds interchangeable lens camera.
It features the same 17.4 x 13 mm (Four Thirds) 20MP BSI stacked sensor and TruePicX processor combo as the original OM-3; however, it has an infrared cut filter placed in front of the sensor that is tuned for near-100% transmission of the Hα (Hydrogen-alpha) light emitted by nebulae. This allows users to capture these celestial cloud formations.
The camera also includes several new and existing computational photography modes, including three new color profiles, Handheld High Res Shot, Starry Sky AF, Live Composite, and Night View.

The OM SYSTEM 5-axis image stabilization provides up to 6.5 shutter speed stops of compensation for the center and 5.5 stops for the corner. When paired with compatible lenses, the camera supports Sync IS for image stabilization at up to 7.5 shutter speed stops at the center and 6.5 stops at the corner, ensuring blur-free images in a variety of scenarios.
The camera has 1x Micro-HDMI Output, 1x 1/8″ / 3.5 mm TRS Stereo Headphone Output, and 1x 1/8″ / 3.5 mm TRS Stereo Microphone Input.
It records to a single SD/SDHC/SDXC (UHS-II) card slot.
For use with OM-3 ASTRO are two new body mount filters: the BMF-LPC01 Light Pollution Suppression Filter and the BMF-SE01 Soft Filter. Attached directly to the camera body for lens-changing ease and use with bulbous, wide-angle lenses, the BMF-LPC01 cuts light from terrestrial, artificial sources, while the BMF-SE01 blurs and highlights point-light sources, maximizing their pictorial impact.
