Well It appears Another Big gun has decided to give us a movie mode. I’ve read rumors that it might have a full 1080p mode but who really knows. The bigger question is how many purses will I have to snatch to get enough money for it. 1080p recording might heat the sensor up so I wonder how long the clips could be. The five minutes that the Nikon D90 gives you is actually plenty long enough for film making but I wonder if the image would then degrade after a bit. Like during the next five minute burst. This worry has been discussed in many of the photographic forums but no one has actually found it a problem.
I wonder though if the heat of the sensor can degrade the image and a cool sensor can improve it wouldn’t it be a good Idea to cool your sensor all the time especially when doing video. I’ve always wondered why they don’t incorporate some kind of active cooling like they do when they use the sensors for astronomy. This home made example seems a bit bulky but if its mount somewhere. I guess you would also have to hack the camera to make it record over 5 minutes.
