D4 x 5D3 ISO series in ACR, IR raws (large file)
Mar 8, 2012

Same post as in Nikon forum (hope DPR doesn't ban me ;).

ACR default, chroma NR=0. D4 shifted by 1 stop at right for the differential analysis.

D4 is better but bang for your buck 5D3 would get my money, 6400 iso would be plenty enough for me.

When everyone saw the 5D3 to be 1 stop better on IR, Nikon folks tried to tell the forum that there're dif in speed. And now they come up with images that show 1D4 one stop better. Hahaha. Nice try. It must take you lots of time to do this, but sorry I dont give it my credit, cause I downloaded the files myself and the 5D3 images looked much better.

BTW, if I upgrade from my 5D1, it'll be the D800 cause I want resolution more, but it seems that the ISO advantage Nikon once had has vanished, the fact remains to be seen anw.

Jpegs, lots of NR.

It took exactly the amount of time needed to convert, crop and put on canvas, +- 20 min.

Why don't you post yours?

D800 should be close to D4 up to 3200, then D4 will be better. Re 5D3, D800 should be close up to 6400. Take your pic.

Not bad for a 22mp sensor VS a 16mp, it is now safe to say 1DX will be crowned the new lord of darkness.

I think this is a great thread. And believable for me. Thanks for the trouble. Both cameras are first class.

No it's not. 1DX will only be a stop better than the 5D3, so at the end of the day, there will be no difference between the D4 and the 1DX. Both superb cameras.

ACR default looks nosier for both cameras. I did with all ACR adjustments set to zero. 100% crops. 5D3 size reduced to 16 MP.

Another 5D3 ISO6400 pic here. ACR default makes pic look uglier than they are.

Hello,

based on that pictures it is quite obvious for me:

  • from Iso100 on, there is more reslolution and equal noise with the mkIII

  • from Iso6400 on, there is more grain in the mkIII pictures, but still a higher reslolution with the mkIII.

But to put into a correct relation - the differences are quite minor.

Very good!

Best regards,
Daniel

Great work.

Both great cameras, looks identical up to 6400 and then the D4 is better (but only by a small amount) at 12800 and 25600. Given that the 5D3 has a higher resolution, it's to be expected that it won't be quite as good.

Thanks for the post. I'd give the edge to the D4 a bit for noise, but its the ugly Canon noise pattern that bothers me more. There is less blotchy-ness and "banding" with the Nikon.

Is the 5D3 a little brighter?
In reply to rhlpetrus, Mar 8, 2012

That would be a plus for the 5D3 results.

don't worry, 5D3 is very close, only a stop or less worse, and just half the price of D4.

LSC converter was used
In reply to BillCat, Mar 8, 2012

The thing that makes this complicated is that they used 50mm/2.5 macro with LSC (1.4X 1:1 extender) for Canon which means around 1 stop light loss that they had to compensate with exposure time.

And according to web sources the effect of the LSC aperture is not shown on the exif data.

So unless the exposure correction was spot on for the converter its hard to say.

From your samples it looks like the 5D3 has about 2/3 stop more chroma noise than D4. However 5D3 is sharper and has more details, colour is also stronger. On the 5D3 if you reduce saturation, add a touch of chroma NR and reduce sharpness to match the D4 you will probably find they are very similar across all ISOs.
