Default 5D3 VS D800: Comparison of high ISO RAW

Thanks to the newly released RAW files from Imaging Resource, we can now do direct comparisons between the 5D3 and D800.

Here is a quick and straightforward test:
  • These came from ISO 25600 RAW files, taken from http://www.imaging-resource.com/
  • Used dcraw to convert to 16-bit TIFF before JPEG.
  • No sharpening, No NR.
  • Downsized both to 8 megapixels (PS Bicubic).
  • 5D3 exposure is much longer than D800. We will ignore because testers admitted that light source changes between tests.
  • The 100% Crops of 8 megapixels.














So to summarize:
  • D800 has 63% more pixels
  • D800 has at least 2 stops more dynamic range at ISO 100
  • D800 looks equal or better than the 5D3 at ISO 25600
Sooo... exactly what did Canon gain by staying at 22 megapixels?

Interesting and just as expected. Its not that the 5D3 is a bad camera. Its just that the D800 is a monster camera!

Well played Nikon. Well played.

Speed.

And don't forget, Canon also has the upper hand when it comes to rate button. Don't underestimate the rate button!

No surprise here. This is what I have been saying all along. Only difference now is that we have more proof. More will come.

Nikon has a winner.

Point. But let's try to keep this thread civilized. No need for sarcasm.

Feel free to discuss, but keep cool.

No, not really. I'm not interested in buying a new cam right now. Switching is far too expensive, and I'm more than happy with my 5D2.

Just wanted to deliver these test results because I find them interesting, and I know that many others feel the same way.

Interesting results, thanks for sharing. Nikon doesn't have the banding issue either. However, I'd like to see the ISO 100 dynamic range difference.

How about we just wait and see for final production cameras with proper testing, yes?

Even if the D800 is superior, nothing is preventing anybody from using it. People complain about what Canon is offering like they are stuck in a world where they can't change systems if the other looks better. If Nikon offered a camera I wanted more, I would go for it. Not sure why people get so defensive or against company 1 or company 2 just because of what they are offering that the company they currently use didn't do. You have to weigh the pro/con of each system and chose instead of sitting on a forum and complaining about them.

This will turn into another fun thread, I can feel it already

What a pointless post. Nice work again Tony. I see your Google search "D800 better than 5DIII" is working for you. Keep it up.

I found the 6400 ISO samples in 5D III favor, I didn't look through all the ISO's, but even in this one I'd say it is really close but I think the 5D III bottle looks like there is more detail although the lighting is very different. The 5D III has a lot more color noise in the bowl image.

Congratulation Nikon for this round,
But Nikon needs to do LOTS more before I even consider to go back.

It doesn't have to turn ugly at all. What if the results had been different and Canon was the "winner"? Then the reactions would be all "oooh and aaah".

People are too much in love with their brands. Everything is being taken so personally.

Even if this is accurate, it doesn't really change anything for me. Both cameras are very very good at high ISO. I see no real incentive for me to switch. And the 6 FPS would sometimes be useful to me. It remains to be seen which is better for video which is something I am interested in.

I do think Canon should get their pricing more in line with the D800 though.

Agreed, I think the biggest reason for the negative comments is because the price is so much higher.

Nice try, but I don't think the "Canon defence force" will agree with you. First they will go into a state of complete denial, until they believe that the results are somehow "fixed", and then they will flame this thread to oblivion.
