I won’t cut corners. This camera is fantastic.

I’ll be the first to say it; this puppy ain’t cheap. However, paying sub $3,500 for a cinema-quality picture, you get near perfect footage as smooth as melted butter. It boasts a brand new dual chip Bionz XR processor which caters to a considerable amount of more horsepower to allow for fast auto-focus and auto exposure, as well as bitrate video. It, amgainzly, offers an ISO range of 80-102,400 expanding to a near 40-409,600. Claiming to capture a 15-stops of dynamic range, too, honing in on precise clarity. The camera’s autofocus system has nearly 759 on-sensor phase-tect trigger points to support even the squirmist of “Eye” and “Animal” AF settings.

To impress you even more with its video capabilities, its in-body image stabilization can reduce shake up up to 5 and a half stops. There’s also a 3.2” fully articulating LCD screen, made perfect for the vlogger in mind. With the highest resolution electron viewfinder found on today’s camera market, it shines bright with 9.44 millions dots. WOW. The camera holds up to 2 memory card slots, both of which can accept SD (UHS-II) or CFexpress Type A cards. Including both USB 3.⅓.2 Type 1 micro USB port, it can be powered by using an external power bank, as well.

The video on this camera is truly no joke. Sony’s A7-series boasts years worth of impressive specs and outlining fantastic items, but never have I seen such an impressive setup within a mirrorless camera. Being a Blackmagic fanboy, cinema-quality cameras are my forte and have been for years. I’m confident in saying this Sony beast is a true worthwhile investment for anyone looking to up their professional filmmaking game. You’re able to capture UHD 4K video at up to 120p without pixel binning. This camera is able to record high speed (up to 240FPS) FUll HD video, as well. While Sony claims that the A7SIII can record for up to an hour at 4K/60FPS, thanks to that improved heat dissipation, I’d suggest recording for a little less as an expectation. It offers both Long GOP and All-intro compression with a maximum bitrate of 600MPS. It’s able to record 10-bit 4:2:2 ratioed footage and both S-Log2/3 and HLG are supported. Of course, the full-frame capabilities include 16-bit RAW footage at up to 60p that’s later transferred to an output for external recording. A standard sized HDMI port is there, as well, alongside a mic and headphone jack with an XLR adapter that can be purchased separately.

The 12.1MP sensor resolution means the camera can’t afford to offer 6K, let alone 8K, instantly putting it behind other cameras on the market that now offer up to 12K. However, the quality of retention you receive in 4K is truly all you need, unless you’re a high-brow pixel peeper that can’t shake a mere miniscule lower resolution. Alongside huge improvements with handling and connecting to low-light scenarios, this hugely impressive hybrid video camera is the best money can buy.

In Detail:

As briefly mentioned above, Sony’s improved sensitivity performance is ramped up by enabling the A7S III to identify subjects within low-light conditions than other cameras with inferior sensitivity levels. Pretty much a game-changer for any landscape artist looking to capture scenes in that famous blueish after-light glow. When it comes to power, their latest Z battery delivers a 60% improvement rate over the performance of previous models and up to 95 extra minutes of video capture, on paper. It can comfortably capture 4K video for an excess amount of time compared to its competition.
