In this article I’ll compare the Nikon D750 versus D810, Canon EOS 5D Mark III and Canon EOS 6D. All four are Full-frame digital reflex cameras.  It’s hard to decide which camera to buy, especially if this is your first FF camera and even more if this is your first DSLR camera. If you currently own either Canon or Nikon compatible lenses, you probably going to buy the camera which is compatible with your current lenses. That said, it’s always interesting to see how those three cameras differ. So without further ado, let’s learn about the key differences between those three cameras.

Upgrading From APS-C to Full-Frame

Upgrading from APS-C camera to a FF is a major decision. Some people already know that they must upgrade to adapt to their professional needs, others might prefer upgrading for its advantages. Among those advantage are:  better high-ISO performance, better sharpness and more detailed image, take advantage of the actual focal-length of the lens and enjoy a wide range of ultra-wide angle lenses, improved color accuracy, higher dynamic range, shallower depth of field, higher resolution without a strong negative effect on image quality (can also do larger printing with better quality), etc.

Whatever are your reasons, full frame cameras can certainly help you become more creative if they fit your shooting style. Of course full-frame cameras are more expensive than APS-C based cameras. This is one reason why not everyone  buy those cameras.  We’ve seen quite a large drop in price in the past couple of years, but still full frame cameras are significantly more expensive than most of the cropped ones.

As you can see from the above price list, the Canon 6D is the cheapest FF camera in our comparison, but still more expensive than APS-C cameras. Both Nikon and Canon have introduced an entry-level FF cameras (Canon 6D and Nikon D610), which should offer a cheaper entry price for those who want to dive into the world of full frame photography.

In this comparison article we’ll focus on two cameras from each company: The Nikon D750 and D810 and from Canon, the 5D Mark III and the 6D. I’ve added the 6D into the mix in order for you to see how a cheaper FF camera can compete against the more expensive models.

In this section I’ll compare the key specs of all four cameras side by side and add my side notes. Here you can get a clear view of the key differences between those four cameras, so let’s get started.

By going over the key specs of each camera, you can see that all the four cameras are very capable cameras. The were designed from the ground up to appeal to those photographers who demand more from their cameras. These are professional tools that are suppose to match the creative  mind of the photographer, while posing as less limitations as possible.

That being said, there are some significant differences between those four cameras. If you search for a camera with the most robust AF performance, you’ll probably should be looking at the 5D Mark III, D810 or D750. If you want a very high-resolution output, nothing beats the D810 36.3MP effective resolution.  If video shooting is your cup of tea, you should probably be interested checking the 5D Mark III with the ability to choose between two video compression formats, while it also has both mic and headphone inputs.

It’s all a matter of which camera best answer your specific needs as a photographer. I personally prefer the Nikon D750 for its 1080p60 video recording, excellent subject-tracking performance, AF low-light performance, tilting LCD and relatively low price.

If I owned either Canon or Nikon lenses, I’m not sure that I would hurry to switch. So before making up your mind, make sure you fully understand the differences between those four cameras. Hopefully this comparison gave you a good understanding of the key differences between those four cameras, so it will be easier for you to continue your research on those cameras later on.
