The Canon ME20F-SH camera was announced well before the Canon EXPO this past week, but definitely fit into the theme of new product lines and ideas. If you don't remember, this specialized camera is capable of shooting at ISO 4,000,000!
The camera isn't available until December and will set you back $30,000, but some of this technology is sure to trickle down into consumer products eventually. For now, this is definitely a niche product for the professional production world.
The video below shows some great examples of what's possible at such high ISO, especially when turning the night into day.
