As the 2nd generation of mirrorless cameras with the large-diameter Z mount, these cameras promise increased reliability in output through the adoption of dual image-processing engines and card slots. While size and operability remain similar to the first generation, on-site workflow efficiency and output reliability have been improved through advances in continuous shooting and AF performance. The addition of the MB-N11 power battery pack, ideal for vertical shooting, increases the number of possible shots while also offering a firmer hold on the camera. It supports hot-swap, making it ideal for extended use such as with video recording.
