While I have not experimented with it yet, my Coolpix 5000 does have a max of about 5 minutes. Still too short for many applications, but plenty for others. Speaking of what the future holds for film, I actually wish we could go to the past instead. To the days when Ansel Adams and his buddies had the super-thick emulsion films that gave such amazing tonal ranges. Oh, well. Ansel was never able to shoot 40 frame bursts at 1/4000 of a second either.
