AND IT NEEDS TO BE CHEAPER THAN THE 1DX OTHERWISE WE MAY AS WELL USE MEDIUM FORMAT DIGITAL
you obviously don't have a medium format! they are a pain in the ass to use, so far behind in technology. price isn't everything, i want it to do the best job it can, price isn't the most important factor for a big chunk of the market.
what i need as an advertising photographer is more speed, more iso and lots of megapixels. my p65+ has enough pixels, it just cant be used in many situations. if canon can release a decent high megapixel camera that can do iso 800 at 3-5 fps, they will own the high end of the market.
You noticeably didn't read my sig. I use a H4D50 for wedding, studio and landscape photography.
Medium format is cumbersome to use but well worth the grief. The Hasselblad lenses are the best in the world, the colour, also world class.
The majority of people using such large file sizes will be studio and landscapers. Run and gun wedding togs just don't have the need (in general) for such high file sizes. I use mine for wedding stuff for things like flowers, panoramic building shots, group shots but the rest the 1DX is used for.
I would trade down my H4D50 but the camera would have to be CHEAP because I know for a fact I would be losing out on the quality medium format affords me. When it comes to high resolution sensors I'm not fussed about ISO performance but ultimate IQ. I know that to squeeze than many pixels onto 35mm is a compromise. As are the lenses. They just aren't good enough compared to H series stuff.
Heck I may even buy a big mp Canon and keep the Hassy. It's that good. I wouldn't dream of shooting a whole wedding on a big MP Canon though. I hear about D800 owners downsizing all their image files to fit onto a DVD.
