- Live ND: Simulate the effect of a neutral density filter, allowing for slower shutter speeds in bright conditions.
- Focus Stacking: Automatically combine multiple images shot at different focus points to create a single image with extended depth of field.
- HDR Shooting: Capture a wider dynamic range by combining multiple exposures.
- Starry Sky AF: A dedicated autofocus mode for precise focusing on stars and celestial bodies for astrophotography.
- Live Composite: Ideal for light painting and star trails, this mode composites only new light into an image, preventing overexposure of static elements.
