<H1>Canon EOS-1D X vs. EOS-5D Mk III analysis</H1>

Canon EOS-1D X 

Canon EOS-5D Mk III

I have been a wildlife photographer using Canon equipment for 25 years and often asked by photo enthusiasts, whether the Canon 1D X or the 5D Mk III is a better camera and which body do I prefer. My experience with Canon professional gear started with the EOS-1 series when it first came out in 1989 and the EOS-1Ds and EOS-5D series when they first appeared on the market in 2002 and 2005 respectively.

My answers to the two questions are, what type of photography do you shoot and how much do you want to spend? This analysis will not have photos, charts and graphs and assumes the reader is already familiar with Canon equipment. It will get straight to the point on my opinion of the two cameras from the standpoint of a photographer out in the field.

First, let us compare the major specs and advantages of the EOS-1D X vs. EOS-5D MK III :

• Sensor Resolution :  18.1 MP  vs.  22.3 MP
• ISO Sensitivity :  100 - 204800  vs. 100 - 102400
• Processors :  Dual DIGIC 5+ and 1 DIGIC 4  vs.  One DIGIC 5+
• Recording Media :  Two CF slots  vs.  One CF and One SD slot
• Higher Frame Burst Rating : RAW 38 vs. 18 rated
• Viewfinder :  0.76X  vs.  0.71X
• Burst Rate :  14 fps  vs.  6 fps
• Autofocus :  61-AF points  vs.  61-AF points
• Cycle Count :  400,000  vs.  150,000
• DxOMark Sensor Score :  Overall - 82  vs.  81
• Low Light Performance :  2786 ISO  vs.  2293 ISO
• Weight and Dimension :  6.2 x 6.4 x 3.3 @ 3.37 lbs  vs.  6.0 x 4.6 x 3.0 @ 2.1 lbs.
• Metering Range : EV 0-20 vs. EV 1-20
• Advanced Metering System : 100k pixel, 252 zone RGB vs 63 zone iFCL
• LCD Brightness Levels : 7 vs. 3
• More custom functions : 31 vs. 13
• Faster X-sync Speed : 1/250 vs. 1/200
• List price :  $6,799  vs.  $3,499
• EOS iTR AF (Intelligent Tracking and Recognition AF including facial recognition)
• Faster AF driven by more powerful battery pack (with select Canon 'L' lenses)
• AF point-linked spot metering and Multi-spot metering
• More advanced self-cleaning sensor
• Accepts optional focus screens
• Superior Weather Sealing
• Built in vertical grip
• Less high ISO noise
• Built-in Ethernet Port

Both cameras are excellent performers out in the field. The 1D X is completely weather sealed and can stand up to most conditions. AF is lighting fast and high ISO performance are superb and as you can see from the specifications above, they are almost evenly matched in performance but the EOS-1D X edges out the EOS-5D MK III in Sensor Score, Low Light Performance, burst rate and cycle count, while the 5D MK III has an edge in pixel count. So, going back to the original questions posed to me :

Q : Which is a better camera ?

A : They are both great cameras in their own right. If you are primarily a Wildlife photographer, the obvious choice is the EOS-1D X. It comes through for me under extreme conditions with little fuss and stands up to harsh use but if you are into Portrait and Landscape photography, the higher megapixel count in the 5D MK III will allow a slightly more robust cropping and lends itself to very big photo prints.

Q : Which camera do you prefer ?

A : If I were strictly a Landscape or Portrait photographer, I will pick the EOS-5D MK III. A photographer shooting both Wildlife and Landscape/Travel will do better with the EOS-1D X.

Q : Which camera is the better value (price dependent) ?

A : Without a doubt, I have picked the EOS-5D MK III as the best value in full frame DSLR camera on the market today.

Q : Which is a better camera, overall ?

A : Without another doubt, the EOS-1D X excels in all categories but at a price some may not want to, or cannot afford. Good, used ones will appear on the market eventually.

Q : Which camera would you buy (price dependent) ?
A : The Canon EOS-1D X represents the pinnacle of Canon's camera technology. There is really no substitute to shoot with the latest 1D. The performance, feel and ruggedness of the camera exudes confidence. I have not bought the EOS-5D MK III because I still own the original 5D and I have the EOS-1Ds MK III as well. So, there is little room in my equipment bag for another full frame camera but the price of the 5D MK III is now down to $2,600 on eBay (limited quantity) and is tempting me by the day.
