Canon EOS-1Ds Mark IV: the rumors begin

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:

	Canon EOS 5D Mark II	Canon EOS-1Ds Mark III
Price (body)	$2,699	$7,999
Sensor	21.1 megapixel CMOS	21.1 megapixel CMOS
A/D conversion	14 bit	14 bit
ISO sensitivity (expanded)	ISO 25,600	ISO 3200
AF system	15-pt AF 6 center AF assist points; 3 center f2.8 and wider	45-point AF 19 cross-type points; 26 Assist AF points
Continuous shooting frames best quality JPEG/full-size raw	3.9fps unlimited/14 (with UDMA card)	5fps 56/12
Viewfinder	98% coverage magnification n/a interchangeable focusing screen	100% coverage 0.76x magnification interchangeable focusing screen
Shutter durability	150,000 cycles	300,000 cycles

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.

Mmmm, I think it will be slightly different.

- Full frame, definitely.
- GPS
- Wifi
- Same battery as Mark III
- Authenticity module
- Prepared for 3D shooting with several DIGIC V processors
- Prepared for 3D shooting, mount for 3D lenses
- Let go of the Ds, just EOS 1D-M(ulti-animal)
- Cradle for the several interfaces such as HDMI
- Separate USB v3 interface
- Parallel CF, SD and internal flash of 32Gb
- 18-bits color depth
- ISO 25-50000 spotless
- HD 1080p video possibilities WITH AF
- internal stabilization of the sensor and on the lenses, so always perfectly balanced
- over pressure in the body, so dust never can enter the body
- 14 frames/second in RAW or JPEG, 60s continuously

SRP: ? 5500

That's the things why we need gps, even wide or big LCD or even video feature
