It has two memory card slots, allowing you to store more photos without switching cards. This is particularly useful on long shoots when you need more space.
It allows you to shoot a panorama 360° in every direction, by stitching together multiple shots that you take while turning on the spot. This creates a spherical 360° panorama, which allows you to look around in all directions instead of just horizontally.
A gyroscope is a sensor that tracks the orientation of a device, more specifically by measuring the angular rotational velocity. Initially, they were built using a spinning rotor to detect changes in orientation, like twisting or rotation.
A compass is useful for gaming, maps, and navigation software.
A multi-lens camera captures two or more images and overlays them. This technology creates sharper images, especially in low light conditions, and allows you to use effects such as softening the background.
