The X-T4 is the pinnacle of the X Series, delivering the highest performance in both stills and video. A new shutter unit has been developed to be fast, durable and quiet. Combined with the fastest ever autofocus performance in an X Series camera, thanks to the development of a new algorithm. The X-T4 is also the first model in the X-T Series to feature in-body image stabilisation (IBIS), dramatically boosting the potential of the camera for stills and video shooting. The stand-alone video mode is now activated with a simple switch, and the use of digital image stabilisation in the video mode provides unparalleled shooting smoothness. This allows users to immerse themselves in video production. The new Film Simulation mode, ETERNA Bleach Bypass, simulates the traditional film processing technique to create a unique world of low saturation and high contrast.
