Good morning! If the Canon 5D Mark II press release doesn't get you revved up today, even without drinking your coffee, you might not have a pulse!
The press release claims: "Along with the ability to capture full HD video clips at 1920 x 1080 resolution, Canon's EOS 5D Mark II Digital SLR camera features a 21.1-megapixel full frame 24 x 36mm CMOS sensor, DIGIC 4 imaging processor and significantly lower noise, with an expanded sensitivity range from ISO 50 to ISO 25,600."
Things that caught my attention: The expanded ISO range (how well will that high end really look? Could it be better than the new Nikons, which look amazing?), the multiple RAW sizes (three), and of course the HD video features.
The video features seem to be fairly well thought-out, unlike all the (premature, in my opinion) buzz around the Nikon D90's features. Where the D90 limits video to 720p and five minutes per recording (and a few other restrictions), the Canon 5D goes up to 1080p at 30 frames per second and either a 4-gigabyte recording size or a 30-minute duration, whichever comes first. I also particularly like that the Canon 5D uses MPEG-4 Quicktime and that the camera actually has a stereo microphone input! It would seem that Canon wasn't reacting to a possible Nikon advancement in this area, but to the RED HD video cameras taking the movie world by storm. The thing to check out will be how well does the Canon CMOS sensor handle video and the inherent skew and wobble of slow imaging chips (ie: "jelly vision" - see this clip of the D90's nasty motion).
