E-M1 Mark III ASTRO + Body Mount Filter Set

A camera specially designed for astronomy that is compatible with Hα radiation and captures the vivid colours of celestial scenes.

The OM SYSTEM E-M1 Mark III ASTRO is a dedicated camera for astrophotography that optimises the IR cut filter located in front of the image sensor of the mirrorless single-lens camera E-M1 Mark III for astrophotography, allowing you to capture colourful red nebulae that are popular among astrophotography enthusiasts. In addition, the filters included with this product, OM SYSTEM's computational photography, and M.ZUIKO DIGITAL lenses enable a wide range of expression from starry sky photography to full-scale astrophotography, such as constellations and nebulae.

01 Captures Hα radiation and beautiful red diffuse nebulae that cannot be seen with the naked eye in vivid, high-resolution images.

The OM SYSTEM E-M1 Mark III ASTRO has an IR cut filter in front of the image sensor that has been optimised for optical characteristics to achieve approximately 100% transmittance of Hα rays, which are important for astronomical photography. This allows you to vividly capture the beautiful shapes and colours of nebulae that emit light from Hα rays, which are difficult to capture with ordinary digital cameras.

02 Covers a wide range of photography scenes, from starry sky photography to astrophotography.

Combining a wide variety of M.ZUIKO DIGITAL lenses, from wide-angle to telephoto, which can be selected according to the subject, you can capture beautiful images of various celestial objects, from magnificent starry skies to specific constellations and distant nebulae. In addition, using a commercially available Micro Four Thirds compatible adapter, you can attach it to an astronomical telescope and take pictures.

03 The stacking process of the High Res Shot function enables shooting in higher quality and with greater detail.

04 Useful support functions for astrophotography.

Custom mode includes convenient settings for starry sky photography

The camera is equipped with convenient settings for starry sky photography in the custom modes C1 and C2 (mode dial) to make it easy for those just starting astrophotography. In addition to the initial settings, such as setting AF mode to Starry Sky AF and LV Boost to On2, frequently used functions in the astrophotography workflow are assigned to buttons so that they can be called up quickly. While it is common to finish astrophotography by adjusting the colour tone and other aspects during post-shooting development, the custom modes C1 and C2 also have settings suitable for astrophotography, such as white balance and tone curve, so that natural images can be obtained even when output from the camera.

C1 setting: This mode uses Handheld High Res Shot to capture high-resolution astronomical photographs. Use a tripod or equatorial mount to take photos.

C2 setting: Drive mode is set to Single Shot. Image stabilisation is set to S-IS AUTO to support handheld shooting.

*Each setting can be changed/overwritten to suit the subject and photographer's preferences.

Body mount light pollution cut filter BMF-LPC01 (The body mount filter is included with the E-M1 Mark III ASTRO and sold separately.)

Light pollution filters cut out light from artificial light sources such as city lights and street lamps. This prevents colour casts in the night sky, allowing you to capture the original beauty of nebulae and constellations more vividly. In addition, since the area near the horizon is most susceptible to light pollution, they are also effective when photographing constellations rising in the eastern sky or setting in the western sky.

Body mount soft filter BMF-SE01 (The body mount filter is included with the E-M1 Mark III ASTRO and sold separately.)

The high-resolution M.ZUIKO DIGITAL lens forms a clear point image of stars, which are ideal light sources. On the other hand, because many stars are recorded as point images, representative stars may not look impressive. By using this soft filter, you can achieve the effect of blurring and emphasising point light sources, making brighter stars appear larger and more blurred, and the colours of the stars are also emphasised, making the stars and constellations stand out.
