The full-frame Exmor R sensor with dual base ISO of 800/12800 delivers clean 4K footage up to 120fps with 10-bit 4:2:2 color, making low-light shooting a core strength rather than a compromise. Its compact 889g body integrates professional XAVC-I recording and a 627-point phase-detect AF system with Eye AF, offering cinema camera performance in a handheld form factor without in-body stabilization. This camera is best for documentary filmmakers and event videographers who need a lightweight, weather-sealed body with robust autofocus and high frame rate options for run-and-gun production.
