With the Rokinon 12mm f/2 lens that I just got, I have an even wider field of view than before and roughly triple the light intake potential. The video has 3 parts to it. First, I have the control, the previous lens I had. Second, I have the test, the new lens, from the same position. I start it with as close to the original aperture as I can get. Then I make the lens wide open for maximum light intake, triple what I could get before. Following that, a video from my primary location in which I do astrophotography from. My camcorder stands almost no chance with this and yet this camera with this lens does very well. And to think I can still go brighter yet.... My camcorder can just barely pick up on the stars. Here, the stars can get picked up very well.
