A7S III - redefining low-light performance again?


Senior Member
In 2013, the A7S astonished the world with it's never before seen 12MP low light sensor. The bar was set so high, it's successor, the A7S II, did not really make a dent.
Now, rumbling of the new quad bayer sensor with a low resolution of just 15MP is getting videographers excited again.
The new sensor is said to have 4 receptor pixels for each color square instead of just one. Under low light conditions, all four receptors work together to produce a higher signal strength.
This new sensor design, may mitigate against old penalties for shooting in APS-C mode especially at the long end of superzooms such as the 18-200mm or 24-240mm where f6.3 could prove too dark for low light venues. If the A7S III continues in the A6400/6600 trend of no recording limit, it will again prove itself as a fabulous video camera that may even give Sony's own FX9 a run for the money. The two missing feature of touch focus and extreme low-light in the FX9 makes the A7S III a much more compelling buy.
