The highly-regarded Sony a7S is known to be a monster in low-light situations, a fact demonstrated by a number of short films have used moonlight as the only light source. Those projects are eye-opening, but another way to see just how good the camera�s high ISO quality is is to compare it with other well-known cameras.
That�s what photographer Tony Northrup does in the short 1-minute comparison above, pitting the a7S against the Nikon D810 and Sony a7 II at various ISOs.
Here�s one still frame of the side-by-side comparison that shows you all you need to know:
The Sony a7S �beat the other cameras by about three full stops, meaning it can film in 1/8th the light and get the same video quality,� Northrup concludes.
Northrup also compared the camera�s 4K video at high ISOs against the Panasonic GH4 and Samsung NX1.
Again, the differences were clear:
This shows why there has been overwhelming demand for Sony�s image sensors in the past few years, and why Sony is raising $4B in funding to ramp up sensor production (one of its primary businesses now). It�s also why photographers are so excited about the newly announced Sony a7R II.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
