The first 28MP APS-C CMOS sensor to use a BSI structure. BSI gathers more light than conventional CMOS sensors and with more pixels, the NX1 records more detail without increasing noise beyond a conventional 20MP sensor. The NX AF System III empowers you with blazingly fast AF. The Hybrid AF covers the full sensor and features 205 phase detection points with 153 exceptionally accurate cross-type sensor points. DRIMe V delivers blistering fast AF and the power to shoot 15 28MP photos/sec. Cutting-edge noise reduction technology, delivers high ISO capable of producing brilliant low light photos and the power to record 4K UHD movies at 30 fps. The NX1 shoots 15 continuous shots every second at 28MPs, and up to 70 shots at one time. And with continuously tracking AF that’s fast and precise, you can just keep your finger on the shutter to capture amazing sequences.
