What only a9 can do This mechanism-free camera can deliver a-class-above performance conventional mechanical SLRs have only sought. For example, this system realizes a totally blackout-free viewfinder while conventional systems can only try to reduce blackout time. A high-speed, vibration-free, silent Anti-Distortion shutter vastly extends the range of shooting situations while a mechanical system can only aim for lower vibration and quieter shutter release sound.a9 provides continuous tracking of moving subjects for foolproof AF/AE while traditional SLRs can only challenge such AF/AE performance improvements. Moreover, a9 allows its viewfinder to show not only images of the subject - available on conventional systems - but also the final image of a shot. Now, thanks to a new image sensor that superbly manages all these roles, you can surpass all expectation with a9. Driving force for full-electronic revolution Innovative full-frame stacked CMOS sensor with integral memory a9 liberates you from the limits of conventional SLRs that rely on mechanical systems. First to use high-speed stacked design, its 24.2-megapixel full-frame image sensor temporarily stores large-volume data in the integral memory for overall 20 times faster readout speed. The combination of CMOS sensor and enhanced BIONZ X image-processing engine brings you true digital freedom. Capture the previously uncatchable High-speed c
