Sony a9 Black 2017
A 24.2MP stacked CMOS sensor and BIONZ X processor enable 20fps blackout-free shooting with a 693-point AF system that tracks with absolute precision. The silent, vibration-free electronic shutter and 5-axis IBIS make it a discreet tool for sensitive environments where mechanical noise is prohibited. This camera is best for professional sports and wildlife photographers who cannot afford to miss a split-second moment.
