Increased buffer memory expands the number of shots in a continuous burst to 177 JPEGs. It inherits some of its speed from the action-optimized A9, including that camera's autofocus system with 693 on-chip phase-detection points and 425 contrast AF areas sensitive down to -3 EV the camera's 10fps continuous-shooting speed includes that AF system tracking the subject and adjusting exposure in 14-bit raw.
Some of the highlights include a new 24.2-megapixel BSI sensor with an updated image processor to deliver native range of ISO 100-ISO 51200, expandable down to ISO 50 and up to ISO 204800. In this Sony Alpha A7 III Review, I compare my experiences with using this popular mirrorless camera versus the Canon EOS DSLRs that Ive used over 15. I don't have info for Australia, but the US price directly converts to approximately AU$2,550 and AU$2,800. The UK will see it sooner, in March, for £2,000 for the body and £2,200 for the kit. The A7 III is slated to ship in the US in April 2018 at $2,000 for the body or $2,200 for a kit with the 28-70mm lens. As you'd expect, the A7 III incorporates advances that its line mates have gotten over the past couple of years, and it looks like you get everything you need and more for a relatively low price. Sony gifted us with a replacement for its 3-year-old A7 II, a solid full-frame that nevertheless needed some updating. When it comes to video autofocus, the A7 III proves very reliable in that regard with fast and precise performance.
