It didn't get a new sensor or processor. Instead, Fujifilm's new mirrorless flagship, the X-T4, got something perhaps even more useful: in-body image stabilization. The magnet-based system offers up to 6.5-stops of stabilization, making every lens in the 29-piece lineup more effective. It also gains a flip-out rear touchscreen LCD with more resolution that will be a godsend to video enthusiasts, who will also be pleased with the 400Mbps, 4K/60fps and 10-bit F-Log recording modes. New algorithms improve autofocus, including eye and face tracking, and a new, more robust mechanical shutter is also quieter and faster. It will be available this summer, in both body-only and kit packages.
