Sure you can use old Nikon lens with aperture rings, but you still won't have the ability to use the meter in live view...

Can anyone confirm the rumour that you cant change the aperture in LiveView for video? IF so, this is a deal breaker.

Hi,

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.
Thanks,
Chad
