Astrophotography
The OM-3 Astro has a modified sensor more sensitive to hydrogen-alpha wavelengths. This makes it better suited to photographing nebulae and emission objects that a standard sensor filters out. The 7-stop IBIS helps for wide-field nightscape shots without a tracker, and the weather sealing handles cold outdoor conditions.
Wildlife and outdoor photography
Beyond astrophotography it functions as a standard outdoor camera with phase-detect AF, bird recognition, and 120fps pre-capture. The modified sensor has minimal effect on standard daylight photography. Full guide →
