DXOMark have released the sensor analysis of the new Canon EOS 5D MK IV.  Without a doubt the highest image quality score of any Canon camera ever.

Now, keep in mind that the DXO score doesn't give a complete picture of any camera, but I've found it to be an excellent source of information when estimating the image quality bang for the buck of cameras I intend to work with.

The 5D MK IV looks like it will be a great camera for Canon shooters, a fine update to the stalwart 5D MK III.

So, how does the 5D MK IV stack up to the primary competition in the market, Nikon?  In the link below, I've called up the DXOMark scores for the over two year old Nikon FX (full frame) bodies, the D810 and the D750. In virtually every measurement category, the new Canon body's sensor is performing right up there with the best Nikon has to offer. The ever so "important" dynamic range of the new camera is much improved over previous Canon bodies, which will give a good improvement to shadow noise on underexposed images.


Overall, I'd place the image quality of the 5D MK IV as outstanding from what I've seen from the Internet and judging by the DXOMark results.  Nothing to worry about here.

The main difference between these three cameras is of course the menu and user interfaces.  I've always found Canon DSLR's to be much more ergonomic and easy to fiddle with in the field. But, I've always found the Nikon bodies to be more resilient in bad weather and custom configurability.  I shoot with both brands these days.

On the video front, the new Canon body introduces a rudimentary version of 4k video, which in my opinion is more or less useless for anything other than playing around. The D750 does excellent HD video but has no 4k video capability. The D810 also has no 4k, but isn't bad for HD video.  The D750 also has an auto-focus system that is exceptionally good, better than the D810's in fact.  Not having shot with the 5D IV, one can only expect that the new auto-focus system is up to the competition.  The 5D III auto-focus was pretty darn good.


Comparing image noise at high ISO, I see the 5D MK IV as generating very good results up to ISO 3200, which puts it in the same category as the Nikon bodies.  I'd say the overall noise levels of the 5D MK IV are better than the D810 but not quite as good as the D750.  There's less than a half stop between the three bodies though.  No significant difference.


Image resolution, no competition here.  The D810 produces noticeably more detail at 36 mega-pixels.  At 30 mega-pixels, the 5D IV is no slouch and is squeezing out slightly better detail than the D750, landing it squarely between the two Nikon bodies for detail and resolution.  All that said, you won't see any difference in these bodies image quality up to print sizes of 24 x 36 inches.


I call the 5D MK IV a winner if you're a Canon shooter.  Still, I think the use of the Digic 6+ processor indicates the design is still based on 2012 designs.  This could be the last DSLR that Canon releases using this aging microprocessor and sensor tech.

If you're a Nikon shooter you can keep grinning too, as the D810 and D750 will both produce outstanding quality images. Keep in mind that both of these cameras are over 2 years old in the market place so that puts them on the downhill side of their shelf life in the market.  I'd be expecting the new Nikon FX bodies as early as next year and I'd also expect their performance to improve over their two plus-year older siblings.


As for the EOS 5D Mark IV, that $3,500 initial price tag is a little steep though.  I think I'd wait for a rebate or price reduction before selling my 5D MK III.  That's a lot to pay for a camera that's barely just keeping up with the competition's two year old offerings.  Two years is forever in digital technology.
