The Xperia 1 IV was co-developed with the engineers behind the latest Alpha 1 series cameras, renowned for their industry-leading autofocus technology, and with input from professional photographers, who helped tune the technology and refine the photographic experience and results. And just as Alpha photographers expect the same performance in any lens, so the Xperia 1 IV offers the same AF capabilities across all its lenses.0 1
Sony AI algorithms automatically detect the subject as the user intended. Combined with Sony's unique AF tracking and focus accuracy, the subject is always in focus0. The main (24mm) sensor also includes an array of 247 phase-detect focus points, covering nearly 70% of the frame, for incredibly fast, precise focus.
Now you can keep the most challenging moving subjects in precise focus. Using AI and a 3D iToF sensor to measure distance, Real-time Tracking0 can accurately detect and focus on a subject, then keep on tracking it even if it temporarily moves outside the frame. To specify your subject, simply touch it on the Xperia 1 IV display. It works for all lenses.1
With true 85-125mm optical zoom, the Xperia 1 IV offers images free of digital degradation between 85mm-125mm. Combined with optical stabilisation and Real-time Eye AF and tracking0, it's ideal for portraits with optical bokeh.

At Sony, we want you to capture the true colours of the world as your eyes see them. So the Xperia 1 IV uses AI (Artificial Intelligence) white balance based on a huge database of images and an RGB IR (Infrared) sensor to capture and correct colours under any lighting conditions, and deliver true to life results.3
