Some NIKKOR Z lenses incorporate an all-new multi-focusing system, consisting of two AF drive units precisely synchronised to deliver fast, accurate autofocusing, minimize focus breathing in video applications, and enable high-resolution images with minimal aberration to be captured even in close-up shots.
A powerful, ultra-quiet stepping motor (STM) provides fast, responsive and highly precise autofocus control while ensuring high optical performance.
The mechanics of focus acquisition are optimised for the application of each NIKKOR Z lens. In Internal Focusing (IF) lenses, only the internal lens group shifts so the lens can maintain its size allowing closer focusing distance. In Rear Focusing (RF) lenses, only the rear lens group moves for focusing. This makes autofocusing operation smoother and faster.
