The Sony A7II is ideal for night photography. Of course, the camera body is only half the battle, and a powerful lens is just as important. You can adjust the brightness of the display to your individual needs.

I would say this camera puts EVERY DSLR in the shade.
You can turn down the screen brightness and you still have the electronic viewfinder... which is a big advantage over a DSLR. With the optical viewfinder you can't see ANYTHING... precisely because it's dark and the displays in the viewfinder are even a bit blinding and make everything even darker.
