And now we can record video at full darkness thanks to new Canon product ME20F-SH
With 5,5 times larger pixel (and other technical achievements) the new video aplication camera is the most sensitive product on the market reaching an equivalent ISO of 4 milion. Just 2.26 Mpx might not sound too much but it's all you need for 1920x1080 (Full HD) 60 fps video recording.
It works with all Canon lenses and you have option to cancel IR cut filter (astro videographers good news) and use ND filter (useful with such a sensitive device).
Now we can literally see in darkness (well at least cameras can).
