Aside from appeal to stubborn purists, the Sony α9 Electronic SLR Camera negates most of the few practical advantages a strictly mechanical SLR would have once held over non-analog hardware. Packing cutting-edge image technology into a classically handsome and deceptively tough lightweight magnesium-alloy body was the perfect way to demonstrate that this compact SLR can outshine anything its predecessor can do.
No matter how significantly any strictly mechanical SLR reduces its blackout time, it won’t top the Sony α9’s verified blackout-free viewfinder. With speeds up to 1/32000 of a second and no ND filter in its way, the electric shutter’s perfectly silent, vibrationless anti-distortion operation delivers uninterrupted visibility with minimal display lag and 60fps live-view capability. Its capacity to complete up to 60 calculations per second ensures that light travels absolutely uninterrupted through the camera. Thanks to its continuous tracking of moving objects, the Sony α9’s AF/AE could best be described as “foolproof,” complete with an ample timing buffer for monumental high-speed performance, including continuous shooting up to 20fps.
From its razor-sharp, brilliant 4K HD video to the incomparably crisp stills captured under any conditions, the Sony α9’s full-frame stacked 24.2MP CMOS sensor is one standard-setting versatile brain behind what just might be the perfect electronic SLR. This brilliant sensor’s integral memory temporarily stores large-volume data for readout up to 20 times faster overall than the next competing camera, all while managing images up 204800 ISO sensitivity without missing a single beat. As far as longer-term management, the Sony α9 warehouses images via dual media slots built to respectively house both an SD card and your choice of either a memory stick or additional SD card with the options to save RAW and JPEG images to separate cards, copy between storage media, and simultaneously backup 4K video and stills. It also offers the ability to call on its optional FTPS support for encrypted file transfers or its wired LAN transfer to move files to an FTP server.
Thanks to the Sony α9 Electronic SLR’s versatility to perform without a hitch under any given set of conditions, any lingering preference for a mechanical SLR is almost guaranteed to come down to personal preference more than any measure of objectively superior capture quality.
