This is a very geek review/sensor analysis of the EOS 7D Mark II by Roger Clark of ClarkVision. He measured various figures of sensor noise, with an eye on long exposure settings and astrophotography. Well, it seems the 7D Mark II found another spot where it is a game changer.
The EOS 7D Mark II is a “stellar performer in low light situations, especially in the lowest light situations commonly found in astrophotography“. In the conclusion R. Clark writes:
The approximately 10x lower thermal dark current is a game changing factor, making this camera the top Canon camera for long exposure low light photography that I have tested. The superb autofocus system, comparable to Canon 1D series pro cameras with 65 autofocus points is another game changing innovation, as the camera is at a price point that is affordable to more people.
Thermal dark current influences noise because of electrons that collect in the sensor due to thermal processes, a phenomenon that occurs during long exposures. According to Clark’s measures, the 7D Mark II is the top performer when it comes to low thermal dark current. 10% lower than other Canon cameras. The EOS 6D is the next best low light camera in the Canon line-up.
Clark’s detailed examination of the 7D Mark II’s sensor properties is very technical and may not be anyone’s favourite read but it is definitely an insight into sensor analytics beyond DxOMark. Charts and test shots are provided.
The EOS 7D Mark II is on the way to become the industry leading APS-C DSLR. The AF-system of the EOS-1D X, 10fps, and amazing high ISO.
