Thanks for your replies.





I guess what I'm trying to figure out is how to use my camera filming at night.





Let me show you an example. This video was recorded at f/2.8 shutter 30 and iso 2000 (anything lower than 1000 iso is waaay too dark)


Test video


(the quality on tinypic is too low, if you want, you can download a 40mb wmv 1080p video here)





But this is what I am aiming for


Another night in beijing.





Even if they used different lens, can the aperture difference between my 2.8 and their possible 1.0 be THAT substantial for recording a crispy sharp videos? Any tips on how to film like this at night? Thanks again.
