I shoot video walk-through tours for real estate. I have been using my stills camera, Nikon D7000 with a Tokina 11-16 for the video(not happy with noise at low ISO, resolution and aliasing). I'm looking to purchase a new camera specifically for video, the GH2 and deeply discounted 5D ii are top of my list. The most important thing for me is a camera that works well in low/poor light. So, my question...is there a lens for the GH2 that is wide and as fast as the tokina on my D7000? So I guess I'd need something around 6-7mm for the GH2? Any recommendations?
Maybe I'll wait for a GH3 or 5D III...just looking for some of your thoughts.
