The Sony a7R III combines many of the stellar features of the other a7 cameras into one powerful multimedia machine. Here are some of the standout features:

• Updated BIONZ X image processor. This afforded a leap in continuous shooting speed up from 5 FPS in prior models to 10 FPS.
• Internal 4K shooting and S-Log2 and 3 for better gradation from shadows to midtones and a wide dynamic range of up to 14 stops, which offers a lot of flexibility for post production.
• A new Hybrid Log-Gamma picture profile, which supports high dynamic range, helps prevent blocked shadows or blown highlights, and creates instant, lifelike footage without further color grading.
• Base ISO has been expanded from 100-25,600 to 100-32,000.
• Fast Hybrid AF System now offers 425 contrast detection points in addition to the 399 phase detection points (up from 25/399).
• Uses the same high-capacity battery as the a9, which allows up to 530 shots per charge.
• Dual SD card slots, a tilting touchscreen LCD, headphone/microphone ports, and a PC sync-in port for external lighting 

The a7R III has positioned itself as the all-around go-to camera with pro-style operability that's exceptionally powerful for portraits but also extremely well suited for events and commercial work.
