The 1Dsx will do for me provided Canon manage to leapfrog Nikons current world beating performance with the 800E. If they can achieve that, then I will be in heaven, if not, then its goodbye Canon. I'm not hanging about if they continue to produce cameras with noise and banding issues but with excessive ISO figures.
Having said that, my present 5DII is OK for the moment, so I would rather they spent more time getting it right than a rushed "knee jerk reaction".
Just interested, what do you think an $8,000+ 38+MP camera will do for you when you can currently live with a $1,300 21MP 5D MkII? What do you shoot now, and what do you do with your output that would necessitate such an upscale?
Pixel-peep and read DxO charts. That's the current trend for 'photographers' these days, at least from what I've been seeing in here.
