First Spec List
This is the first spec list I have received about the 1Ds Mark IV.

The person that sent this in stressed the 1Ds Mark IV will not set the benchmark for video performance in the Canon lineup. It's felt the camera is too big for a lot of people. There will be a more video oriented full frame camera coming. The 1Ds Mark IV is a still camera first.

-32mp CMOS (New Sensor Technology)
Noise control wasn't the primary goal of the sensor, dynamic range is.

The new sensor requires a new processor, This will be the 2nd camera with DIGIC V.

-5 FPS
No increase in shooting speed.

-Video Features
Video will be about the same as the 1D Mark IV feature wise. There may be a couple of extra bells and whistles.

-Live View
Contrast detection AF will be the fastest yet on a Canon DSLR.

-Form Factor
The camera will be nearly the same shape as the 1D Mark IV. Do not expect any ergonomic upgrades

-Flash Master
There will be a built in flash master to work with a new Canon speedlite.

-Announcement in August
Expect this to receive a separate press announcement.

CR's Take
Canon is always very incremental with upgrades to the EOS-1's. A part of me cannot see the camera getting DIGIC V when the 1D has DIGIC IV.

I will agree that it will not be a flagship video camera.

I'd be surprised if it doesn't come with an improved version of the 7D electronic level.

This could be the beginning of the spec madness. Take it with a grain of salt.

  1. me, and only me on

    Yeah, and they take 1fps!
    Get real, the 1Ds doesn’t compete there. It has a justifiable presence, but it has a smaller sensor, it’s more flexible but lower res.

  2. billy-cuddie's breeks on

    Ye but that is not a constant f/4 we need a crop version of the 24-105mm.

  3. What about the Pentax 645? I can see the 1Ds Mark IV competing with that and similar systems. The costs for MFDB are coming down as well.

  4. FYI, Leica M9 using FF CCD from Kodak, a very expensive rangefinder camera with very expensive prime lenses

  5. Let’s look at the primary purpose for the 1Ds series: A relatively light-weight, relatively less expensive alternative to MF for non-sports pros. Given the existance of the 1D series, why would the 1Ds need higher sensitivities or frames per second? Pros use MF for dynamic range and resolution; but, as mentioned earlier, they’re heavy, slow and expensive; as well as having fewer lens options.

    So what would a commercial photographer want a DSLR for? On-location shooting under time constraints, where high repro quality is needed. Translation: High DR; high resolution; high reliability. Don’t worry about frames per second: 5 is more than enough. Don’t worry about ISO: 600 is fine. Forget video: If a pro wants video, he/she will use pro video gear.

    Now, if only there was an effective way to build in a lightweight, fold-away magnifying viewer and color-balancing controls: Imagine the after-capture timesavings!
