I seriously hope they don't buy out Phase One. Phase and Dalsa have a beautiful thing going, and throwing Canon's now-outdated sensor tech into the mix would only turn gold to straw — not to mention it would have to be heavily AA-filtered and video-optimized to meet Canon standards. When Phase moved from Kodak to Dalsa, they lost the long exposures but gained worldwide acclaim for their colour accuracy and huge dynamic range. And, finally, after years of co-research and development between the two companies, they've brought hour-long exposures back on a Dalsa sensor, mixing the company's class-leading patented high-ISO pixel binning with Kodak's drool-envoking long exposures from yesteryear. Canon has nothing to add to either side of that; lobster-red skin tones and three less stops of dynamic range with all kinds of noise at any exposure longer than 30 seconds. Which is garbage for us stills-only photographers.
I keep reading posts from users asking Canon to bring in the first affordable medium format system. Look at the Pentax 645D. At the time of writing this, its price is about on par with that of the 1D X. And in true Pentax style, any MF Pentax lens you find in any pawn shop will absolutely work with the system. That, my friends, is cheap glass. Can't be beaten for price. A close second is second-hand Leaf backs attached to Mamiya AFD bodies. You can actually get yourself a whole 20+ MP kit with a couple lenses for less than $5000 if you're looking in the right places, and it allows you to switch between film and digital. I've got the DF+, but my Phase digital back pretty much lives on my Mamiya AFD. Kill the backup before you challenge the master, right? But if Canon buys Phase, they'd be killing the master to become the backup. That just won't do.
