Looking Ahead

Looking at the Canon 5D Mark II for a day hardly provides enough data to reach conclusions regarding the 5D2. However, the initial results are truly impressive. Unlike the exaggerated claims for the 50D, the 5D Mark II appears to perform as Canon claims. Resolution is as good or better at the same ISO as the original 5D, but the range is extended somewhere between one and three stops in a sensor with 65% more pixels.

ISO performance appears to match the current ISO champion Nikon D700 up to 3200, and the 5D2 reaches lower to ISO 50. We would not hesitate to use either camera for most anything in this 50/100 to 3200 ISO range, which is saying quite a lot. At ISO 6400 there is some noise in both the 5D2 and D700 images, but they are basically equivalent. At 12800 and 25600 the Nikon D700 appears to have somewhat lower noise, but the image also appears softer, which is often a processing tradeoff for reduced noise. This range of the top two ISO speeds needs to be examined in more detail so we understand what is going on and what tradeoffs can and can't be made with each camera to lower noise.

When you also consider that the 5D Mark II has almost 75% more pixels than the Nikon D700, the above comparisons become much more remarkable. To say that a 21.1MP camera is the equal in low noise to a 12.1MP over most of its range is high praise. To see both reach to ISO 25600 with more similarities in performance than differences is icing on the cake.

Our initial testing still points toward the Sony A900 as the resolution champ at normal ISOs, but there is no doubt that the Canon 5D2 is much better at high ISO performance while achieving resolution nearly as good as the A900. It should also be pointed out that if you want high resolution shooting combined with a brisk continuous shooting speed, the Sony at 5FPS matches the just-announced $8000 Nikon D3x at 5 FPS, That is much better at high ISO than the 5D2 specification of 3.9 FPS. Still, it is almost as if the 5D2 combines what is best about the Sony A900 and the Nikon D700 in a single package.

It is too early to draw final conclusions, but there is much to like in what we have seen so far with the Canon 5D Mark II. The high performance we have seen over a 10-stop ISO range will make the rest of the 5D2 testing journey even more fun. Users looking to upgrade from the original 5D will almost certainly be pleased.

    > I used to trust DPR but they are biased against Canon which I don't like.

    huh? i don't think so at all... i think they are pretty fair. they have always rated Canon products favorably when deserved, but remain critical enough to give relatively impartial opinions. if they say Nikon does some things better, it's because they do - Canon is not perfect, and there are a few things Nikons have always done better. (and no, i am not a Nikon user - i have only Canon gear.)

    wesley,

    > It is not the wide ISO wonder of the 5D2 or the D700, but it is definitely the highest resolution image at lower ISO ratings.

    i'm not sure how you came to this conclusion. looking at the ISO100 images, the 5d2 seems to resolve every bit as well the Sony, and with the much lower noise levels i can actually make out a little more detail. in any case, you would need a resolution chart to really determine - did you shoot one?

    > The 5D2 is close in resolution, however - much closer than the D700/D3.

    with half the pixels i wouldn't expect the Nikons to be close.....

    Wow. I'm in love. After three years, Canon finally produces a camera which is worthy of replacing my beloved 5D. I fear, however, that the images produced by this camera will kill my hard drives for sure. I only photograph in RAW mode, saving the images in TIFF.

    Wesley, I enjoy reading your reviews, but for the love of God, please use something else other than that Nvidia box for your test images. It's time to make a clean break, consistency be damned! The thing with noise I worry about it how it affects key facial features (eyes and lips). Your test setup is not as helpful as could be. A feasible alternative is a good quality mannequin head. I hope you will consider it.

    Also, are you going to be doing any comparisons of the leading noise reduction programs?
  • Wesley Fink - Thursday, December 4, 2008 - link

    I will be replacing my test setup with something more useful. However in the interest of bringing you the first real comparison published in just one day after buyers began receiving production 5D2s, I used the setup I already had used for all the compare shots.

    I hope readers will forgive me. Reshooting everything with a new setup would have added several days to the review time and I suspected you wanted this comparison fast.

    I would like to see the same reduced sized samples when compared to the D3/700 with both the Canon and Sony. I'm also of the opinion that it is more useful in showing a real comparison, print size to print size.

    Also, why were the images of the Canon so much denser? That will also affect the way the noise looks.

    Our A900 review "Sony A900: A Closer Look at 24.6MP Resolution and Noise" contains image area adjusted A900 images that match the 12 megapixels of the D700 and the 5D. You will find the review by clicking on the Digital Cameras tab above.

    Yes, I read that review when it came out.

    I mean the new 5D mkII compared to the a900, and the Nikon, with all three (or four, if including the 1Ds mkII) shown at the same size.

    What about the exposure?
  • Lord 666 - Thursday, December 4, 2008 - link

    Agreed that this review was a much improved effort and found it informative as well.
  • tonyeck - Thursday, December 4, 2008 - link

    I am very happy with my 5D mkII apart from one thing - a stuck pixel! It's fine for photographs, and it's almost expected with 21 megapixels... However, with video, stuck pixels show up like crazy!

    Have a look at this still from a video I took:

    Yea...
    That dead pixel looks not good at all. Can't you have the sensor replaced by warranty? I mean, this is not a El Cheapo camera you just bought! Canon should have a replacement policy for dead pixels. I'm glad you bringning this up, as I'm about to buy a 5D2 myself. I will certainly try the video and look for dead pixels.

    Could be a good point if Anand, Wesley Fink, looks att dead pixels and the manufacturers policy with this issue. The more pixels, the bigger the chance. It's the same problem as the LCD screen buyers have. Would be an interresting article indeed.
