February 27, 2018 Tobias Gelston

https://youtu.be/rdZaqXd6hMsSony has just announced the a7iii. A followup to their entry level full frame mirrorless a7ii.The Sony a7iii Specs:

Redesigned 24MP Sensor
693 AF Points with A9s Eye-AF system (Better than a7Riii)
15 stop Dynamic Range
5 axis IBIS
10fps with 14 bit raw (also 14 bit raw while silent)
4k HDR, 6k full readout, Slog 2 & 3 and HLG
Uses Z Battery Rated at 710 shots longest battery life of any mirrorless camera ever
Dual SDcard slots, joystick, touchscreen, USB-C,
Available in April for $2,000 - Preorders start Wed

At $2,000 for the a7III you get a NEW BSI 24.2 MP sensor offering- 10 FPS (silent or mechanical shutter), 15 stops of range and 4k Video. Combine that with 425 contrast Autofocus points, 693 phase detection autofocus points, eye AF, 5-axis in-body stabilization and a redesigned body that offers a bigger grip, a focus point joystick and a touchscreen. Not to mention the longest battery life of any mirrorless camera.With a lot of tech being brought in from the a7RIII and a9 it's fast. You can capture up to 177 JPEG images, 89 compressed RAW, or 40 uncompressed RAW images before filling the buffer. As with the other models, there is a partial lockout of camera functions while the data saves to the memory card. AF is about twice as fast as the A7II and significantly improved low light capabilities. The Eye-AF system is BETTER than the a7RIII! And it's REALLY good in the A7RIII!Offering 4K video with HLG(HDR) and S-Log2 and S-Log3. The 4k file is downsampled from 6k which when working off a 24mp sensor should give excellent low light results. Full HD at 120fps to round it out.The design mirrors the a9, a7Riii batteries with dual SD card slots, slot one is SDXC II compatible. Same battery as a9/a7riii, the NP-FZ100 battery provides 710 shots per charge, that is actually the highest rating of any mirrorless on the market battery, the a7RIII is rated at 650 shots. USB-C for fast transfer of photos and video, tethered shooting and doubling as a power supply. There is also a micro USB port.My full review from Vegas will be released soon, don't forget to follow on Instagram at @photorectoby or subscribe to Youtube to be notified of the Sony a7iii review release
