When Sony introduced the original a9 mirrorless camera a couple of years back, it gave fast action sports photographers a smaller, lighter, option with which to ply their trade, and provided them with the opportunity to disrupt the dominance of Canon and Nikon in that particular area. Now, they are hoping to bring even more sports photographers in to the Sonysphere with the newly announced Sony a9 II.
Outwardly, the Sony a9 II looks and feels the same as the a9 with the (slightly larger) control dials and buttons located in the same places, so if you’re used to shooting on the original, transitioning to the a9 II would be a snap.
Weather sealing around the body has also been upgraded, offering better dust and moisture resistance and the grip has been made slightly larger as well.

Internal Changes
The a9 II shares the same 35mm full-frame stacked 24.2 MP Exmor RS CMOS image sensor with integral memory as the original a9 but features an upgraded BIONZ X image processing engine which Sony says will deliver faster, more precise AF/AE detection, image processing, face detection and EVF response time.
The AF Algorithms have also been upgraded to deliver faster, more reliable tracking of fast, erratically moving subjects which are common when shooting sports.
Autofocus remain the same offering 693 focal plane phase-detection points that cover almost all of the frame.

Built for Speed, Reliability and Productivity The α9 II offers advances that answer the demands of professional workflows, including sophisticated operability and network connectivity for enhanced support in the field, rugged go-anywhere reliability and unrivalled speed.
The big feature of the original a9 was its ability to shoot silently at up to 20fps when using the electronic shutter and that hasn’t changed with the a9 II. What has changed however, is the bump in speed when using the mechanical shutter feature.
When using the mechanical shutter, the a9 maxed out at (a fairly respectable) 5fps. However, the a9 II features a redesigned shutter system, now maxing out at a blisteringly fast 10fps, double that of its predecessor.
Sony also says that the new mechanical shutter system is designed to automatically detect flicker and adjust the shutters timing to help eliminate the exposure and colour variations that can happen when shooting at high speeds. These improvements will also work when shooting high speed with auto-focus and/or auto-exposure tracking enabled as well as when shooting with a flash.
The a9 II offers 5-axis inbody image stabilization providing up to 5.5 extra stops of exposure and also works when shooting video.
Connectivity has also been given a boost, adding a USB Type-C port supporting fast USB 3.2 Gen 1 date transfer speeds. It also adds a 1000BASE-T LAN terminal allowing for high-speed transfer of images with an FTP function.
The dual memory slots each support both UHS-I and UHS-II SD cards.
A digital audio interface has also been added to the camera’s Multi Interface (MI) Shoe allowing for Sony’s new ECM-B1M Shotgun mic or XLR-K3M XLR Adaptor Kit to be connected directly to the MI Shoe.
