This one was shot in an hour with two cameras, Sony AX2000 and Canon 600d.

And this one was shot entirely with Canon 600d and Samyang 35mm f1.4.
It was shot wide open with ISO 1600.
The street where this was shot is very dark, but at f1.4 and ISO 1600 you can even see night sky clearly on some shots.
But if you watch fullscreen, you can see there is a fair amount of noise, but it's acceptable.
