SenScore recently tested the image sensor of new released Nikon D5 full frame DSLR camera. It turns out that D5 has the best image sensor according to SenScore.
D5’s sensor is better than D4s, a7RII, D810 and 1D X Mark II:
From SenScore:
Nikon’s latest full frame low-light sensor cannot match the previous generation’s excellent noise performance, but in every other aspect, it manages to improve on its predecessor. However, the moderate improvements are somewhat disappointing for a new generation flagship camera. Obviously, a camera is much more than just sensor performance, but the fact that this is the best sensor Nikon can offer 4 years after the launch of the D4, D810 is worrying all the same. Still, the D5 is a great camera and the new #1 in the database.
