Canon EOS-1Ds Mark IV: the rumors begin

After only a year on the market, talk starts about an update to Canon's flagship dSLR.

Mark III ready for replacement?

After just about a year on the market, the rumors have started about a replacement for Canon's flagship EOS-1Ds dSLR. The blog trail, which seems to have started in a forum at photofans.cn but which I read on Photography Bay, speculates that the specifications will include the current sensor, but two Digic 4 processors which will enable a bump to ISO 12,800 and a burst rate of 6.8fps, HD video capture, and a jump to a 69-point AF system.

Though Canon Rumors gives this scuttlebutt its second-lowest credibility rating--"From a 4-legged animal"--as a possible feature set it makes some sense. Here's how the current model stacks up against its newest sibling, the 5D Mark II:

Clearly, the newer 5D Mark II outspecs its older, much more expensive brother in a way that makes the Mark IV inevitable sooner than the typical 18-month product cycle might support. And though the specs may be someone's wish list rather than the reality, it's a pretty sensible wish list. (I'd throw in a built-in wireless flash controller, though.)

But whether it's truth, lies or wishful thinking, you can bet we'll be hearing about it ad nauseam for the next 3 to 6 months.
