one odd thing is they claim 18MP was needed because they can\'t drive more MP at 12fps and yet 7D already does 18MP and 8fps and 1D4 16MP at 10fps and digic 5+ is supposed to be a huge boost relative to past generation compared to the past and yet the 18*12 they get is only the same increase they had in the past so something doesn\'t add up, maybe the extra jpg CA, DNR etc. takes a lot of power or it was really other factors like chip read and so on
As far as I understand it, the bottleneck isn\'t so much the speed of the image processor(s), it is more a question about how fast they can \"drain\" a big full-frame sensor of image data. Small sensors are apparently faster to deal with. I\'m no engineer so please don\'t ask me to explain
yeah that would make a lot more sense
although i still wonder why they needed two digic 5+, maybe so it can do lots of fancier image processing when desired
or for the video scaling
