Canon 1D Mark IV vs Nikon D3s

It's about a wash between the 2 cameras outside of what we already knew. The high ISO performance is superior out of the camera on the D3s and it's lower megapixel/larger sensor.

Again, take it for what its worth.

Canon EF 70-200 f/2.8L IS II
The lens will retail for $2499 USD. I'm still searching for places in North America to preorder this thing. I have yet to see pricing in Canada.

thanks Skip & Adam

  1. How can you claim up to ISO 102400?? Canon !!!
    What is your standard ?
    Definitely, it is different from Nikon.

    This is very interesting.

    Look, three years ago I needed to do a night shot of the Milky Way for National Geographic, so I went out and bought a Canon 5D and a 35mm f1.4. Easily the best performing camera in low light at that time. That camera made great images. The 35mm f1.4 is sharp if you got it in focus (sort of an oxymoron there , right?)

    Two years later and I’m doing a story on light pollution requiring a lot of low light photography and another shot at the Milky Way. So I went out and bought a Nikon D3 and a 14-24mm f2.8. Easy choice. Easily the best low light camera available at the time.

    Now, if I were doing that again the answer would be simple. The best low light camera available today is the Nikon D3S.

    But high ISO performance matters for more than just low light shooting. It is also a measure of how much you can open up the shadows in post processing before noise becomes objectionable. Better high ISO performance equals cleaner shadows.

    As far as megapixels go I really don’t want more megapixels. At least not in the pages of National Geographic and certainly not for the 27″x40″ prints we do in our gallery all the time. I do like the files that come out of my D3X, I must say, but it’s not the extra megapixels that draws me to that camera, it’s be beautiful look of the files that comes from the color depth and dynamic range. They’re pretty. But so are the files that come out of a Canon 1Ds MkIII. They’re just really pretty.

    Sorry to jump in here as an outsider and I don’t mean to rain on anybody’s parade.

  3. I understand there is more to a camera than sensors, but DXO Mark tests sensors only. They dont test lenses, speed, and host of other things, and they dont pretend to. The way they tests those sensors is by looking at RAW files. They are the only ones that run such tests, if someone finds another lab that yields to different results, I’d like to know about it.

  4. ” I’m actually tired of High ISO counting for 50% of a ranking. What a bunch of morons.”

    like the canon FanBOYs you mean, werent you the ones jumping up and down a couple of years back yelling at nikon owners about their miserable high iso perfomance?
