The Sony a7SIII has recieved almost universal praise since it was launched and now DPRTV has finished their review. You can read a summary of the review below:
Great dynamic range
Great high ISO
Sony a7SIII is good for photography but you shouldnt buy it just for photography
This camera is best for videographers that want to shoot photos on occassion
They have shot a few episodes on the a7SIII now
Cine 2 is good for low contrast shooting
Slog2 will give you more dynamic range
Slog3 never worked well before with 8-bit profiles but now Sony has a 10-bit profile with tons of dynamic range
a7SIII is noticibly less sharp than other cameras that super sample due to only capturing 12MP
Less sharpness is the tradeoff for more dynamic range and better low light performance
The 12MP sensor also reads out faster than higher MP sensors
Sony says it reads out 2x faster than the a7SII, but DPR thinks its more than 3x better making it the fastest readout around at the moment
PDAF works well with real time tracking AF, but you have to touch the screen to start the tracking
The only time they have had an issue with real time AF is when shooting log with fixed subjects
AF-S is the work around for tracking errors on still subjects
XAVC HS 4k files are very small but very demanding on your computer if they are too much for your computer use XAVC S 4k
Great slow motion modes and can use the new S&Q dial for 4k 120 or 4k 60, but if you need to capture audio in slowmotion it will be very hard on your computer
Best 1080p you’re going to see on any Sony camera
1080 quality only drops with 240p, but it is still the best 240p around
Overheating is not a problem on this camera even for hours on end
It can over head if you shoot 4k 120p for half an hour then you can overhead
The EVF is exilent, but the quality is much better during playback than while filming
In the past if you were in mixed lighting the Sony would white balance wrong, but now Sony has a whitebalance sensor in the camera that does an ok job
Auto changing white balance changes slowly so be aware if you’re trusting the camera
The RAW video feed coming out of the full size HDMI is nice, but this camera wont let you dial in the ISO or white balance like other cameras, but it should come via future software updates
High ISO is still very good with very little color noise, but chris wouldnt go past 51k ISO for professional work
The menus are actually fun to use
Best camrea on the market for run and gun video work
No other camera can do what the Sony a7SIII can do
