I purchased the Canon 5D MarkII about one month ago. My primary purpose was to use it in my landscape photography, but I was really drawn to the HD video capability. The one downside to the camera was the lack of manual control in video mode. The user was limited to simply letting the camera do everything automatically in video mode. Today Canon announced the availability in early June of a new firmware upgrade that will now make available to the user manual controls in video mode. The user will have control over aperture, ISO, and shutter speed. This is a tremendous announcement and I am very excited about this new opportunity with the camera. Please stay tuned for further developments and reports on the camera and video opportunities it presents.
