Thanks to an evolutionary leap in image processing power and efficiency, the a7R III combines a high-resolution 42.4 MP back-illuminated Exmor R CMOS image sensor with impressive shooting speeds at up to 10 fps with full AF/AE tracking, as well as beautiful 4K HDR video quality, wide 15-stop dynamic range and high sensitivity with noise reduction of almost a full stop.
Two SD media card slots are provided for still and movie storage (one slot for SD cards or Memory Stick) with the lower card slot being UHS-II compatible for fast write speed. Still or movie data can be simultaneously recorded to both cards for backup, or RAW images can be recorded to one card while JPEG images are recorded to the other. It is also possible to record stills and movies to different cards. Data can be copied between cards while in the camera, for convenient back-up. Sony SF-G series UHS-II SD cards are ideal for situations where maximum transfer speed is required.
The high-capacity NP-FZ100 Rechargeable Battery has approximately 2.2x the capacity of the NP-FW50 W-series battery for more than double the stamina of the W series as used in the a7R II. The optional VG-C3EM vertical grip houses two batteries and when you need serious stamina for long sessions there’s the NPA-MQZ1K Multi Battery Adaptor Kit that can hold up to four batteries. The NP-FZ100 also supports InfoLITHIUM technology, which makes it possible to view the remaining battery power as both a percentage display and five step icon on the camera’s LCD screen.
