So I'm perfectly in agreement on your take on the 1Ds and 1D lines, Craig, but I question why Canon would start to monetize video at this stage when it's been added to every Canon dslr camera released recently. The only thing that would differentiate the 5D line would be some kind of super enhanced video shooting qualities, 60p, 4,2,2, raw codec in one body and just regular old 1080p with standard codec in another.
That alone still doesn't seem like enough to make a difference. Sensor technology, AF tech, processing engines, viewfinders, and body construction are the current standard differentiators between the lines. I just don't' see that changing any time soon.
My wishlist for the 5D series would be to keep it as one body; they could call it something creative like the 5D3. Give it a 32 mpx or thereabouts sensor with improved dynamic range and improved high iso (better by 1 stop than the 5D2, clean iso 6400 please). Weaken the AA filter please. How about dynamic 1.6 and 1.3 crop? Give it a decent AF engine with enough AF points, and for heaven's sake make more than one point as accurate as the center point on the 5D2. Take us to 5fps. Make it fully weather sealed. 100% viewfinder and throw in a high res 3.2 in lcd to boot. One digic 5 processor could power the rig. $3500
My wishlist for the 1Ds line would be to make it more like medium format with upgradeable sensor technology. Body upgrades could come every 7-10 years. Back upgrades 2-3 years. Three nice dense sensor options to the tune of 32mpx, 40mpx, and 50mpx. Significantly weaken the AA filter please. Fast AF, fast fps, dynamic 1.3 and 1.6 crop. How about 10 fps in dynamic crop mode and 6 in full frame mode? Make it rugged, even with the replaceable back (Canon could accomplish this with a sealed recessed design). Give us a huge 3.5 in. high density pixel lcd touch screen and call it a day. Two digic 5 processors could power the rig. $6500 $7700 $8900
