Sony's new a7 III is a serious full-frame mirrorless camera at $2,000

[Shawn Knight]

Sony is billing its new a7 III digital camera as a “basic full-frame model” but that’s a bit of an understatement. In reality, it’s one of the most impressive full-frame mirrorless cameras to date.

At its core is a new 24.2-megapixel back-illuminated Exmor R CMOS image sensor boasting increased sensitivity, respectable resolution and 15 stops of dynamic range at low sensitivities. You also get an updated BIONZ X processing engine that boosts processing speed by 1.8x compared to the a7 II. Indeed, it appears to be the same processing engine used in the new a7R III.

Together, the components produce an ISO range of 100 – 51,200 that’s expandable to ISO 50 – 204,800 when dealing with still images. Autofocus response and tracking has also been improved with almost 2x the focusing speed in low-light conditions and 2x the tracking speed compared to the previous model.

When shooting, expect to be able to capture full resolution images at up to 10 frames per second with continuous AF / AE tracking for up to 177 standard JPEG images, 89 compressed RAW photos or 40 uncompressed RAW images. The high-speed shooting mode works with both the mechanical and electronic shutter.

Elsewhere, you’ll find an autofocus system with 425 contrast AF points that work with a 693-point focal-plane phase-detection AF system from Sony’s a9 model to provide coverage across approximately 93 percent of the frame.

If video is your thing, you’ll be happy to know the a7 III offers 4K (3,840 x 2,160 pixels) video recording across the full width of the camera’s sensor. Sony highlights that the camera uses full pixel readout without pixel binning to collect roughly 2.4x the amount of data required for 4K movies. It then oversamples to produce high-quality 4K footage with “exceptional detail and depth.” There’s even an anti-flicker function to help the camera detect the frequency of artificial lighting and time the shutter to cope with it.

The Sony a7 III is expected to ship in April at an MSRP of $2,000 or as part of a kit with the FE 28‑70 mm F3.5‑5.6 lens for $2,200. Look for it at your favorite Sony authorized dealers or online through Sony’s website.

I have decided to invest in sonys mirrorless offerings and I have to say I'm thrilled. I have the Sony a6000 and I plan on upgrading to the a7 series. I've used several of the a7 series cameras and they are a joy to use. My only problem is that I have large hands so extended periods of time holding it becomes uncomfortable.

To anyone interested in Sony mirrorless cameras, be careful buying lenses. Not all emount lenses transfer from micro 4/3rds to full frame. They list it on their website but you'd never to know look for it if you didn't know it was a problem.

A common problem with many lenses out there today .... another good reason that I'll stick with my old Hassiblad 500CM .....

That has been a thing since crop sensors came out though. The real problem is they aren't clearly marking them like Nikon and Canon do with their lenses. Personally, I'm debating between The D850 and an a7-series. Normally, I would just grab Sony because its cheaper, but I shoot landscape and that 14-24 f/2.8 is just sooooo tempting.
