1. AUTOFOCUSThe AI Detection AF now includes humans, replacing the old Face/Eye setting.It improves precision when the person is facing away, or is smaller in the frame. C-AF has been improved for birds as well.
2. BUFFERThey share the same continuous shooting speed (50fps with C-AF and 120fps with S-AF), but the OM-1 II almost double the buffer capacity with RAW and JPG files.
3. STABILISATIONThe OM-1 can compensate up to 7EV with sensor shift alone, while the OM-1 II reaches 8.5 stops. With Sync IS (body and optical stabilisation), the original OM-1 goes up to 8 stops, while the Mark II maintains the same 8.5EV rating.
4. HR SHOTBoth cameras can capture high-resolution shots up to 80MP (tripod) or 50MP (hand-held). The key distinction is that the OM-1 II can save 14-bit RAW files, whereas its predecessor is limited to 12-bit.
5. Live GND The OM-1 II introduces Live GND (Graduated ND). You can adjust the position and angle, with three steps (GND2, GND4, or GND8) and three types (Soft, Medium, or Hard) to choose from.
