The camera features dual memory card slots, but instead of the latest and fastest CFexpress cards in other Z-series full-frame cameras, the Z f accepts an SD card in the main slot and a MicroSD card in the second. Not the best combination for a full-frame camera of this class, but we believe this has been necessitated by space constraints. Incorporating the slower MicroSD card means slowing down the system especially if you configure it to separate Raw and JPEG files. The card slot is within the battery chamber, which makes it difficult to swap cards while the camera is mounted on a tripod.
You can capture 14-bit Raw images with lossless compression, high efficiency (high), and high-efficiency options and JPEG with fine, normal or basic compression options. There’s an HEIF option as well. The Z f offers up to 14 fps high-speed capture for Raw and JPEG large and Fine images. There’s also a 30 fps mode if you choose JPEG with normal quality. Equivalent sensitivity ranges from ISO 100 to 64,000 without considering the boost modes.
