Canon 1DX vs 5DIII Wildlife Comparison

[garyknrd]

How does it stack up to the 1D mark IV? I picked up a mark IV and was hoping the reduced pixel density would not be noticeable but it is very noticeable. When the AF hits on the 7D it smokes the IV. Or at least mine does. As far as detail goes. I only shoot birds and only have had the 7D and mark IV.
I was going to try the 5D III but with the poor performance in resolving of the IV I am a little hesitant.

I have not tried the 1DIV but I can say the 5DIII smokes the 7D even losing the 1.6 crop factor, it still is better than the 7D both in resolution and in lower noise...not to mention the vastly improved AF capabilities.

Having both cameras for some time now I would agree with something bdunbar wrote earlier in this post.....the 1dx shadow recovery is noticeably better than the 5d3 at higher ISO's.....and the AF system is better for catching action/movement... no doubt about it. 

The extra mp's of the 5d3 do come in handy in good light if your subject isn't moving much, and if that is the only type of wildlife photography that you're doing then yes, the 5d3 would be better.   

But...I've seen a million shots of a bald eagle or bear or wolf...etc, just sitting still in good light...cropped in close.  My point is that those shots get pretty boring pretty fast.....BUT:

1. If you saw two bald eagles fighting in mid air (as Gary samples has shown in the 1dx sample images section) you would want the speed of the 1dx

2. If you saw any big cat trying to capture prey...you would want the 1dx

3. If you saw a mother bear caring for her new cub in the shadows of a forest....you would want the 1dx.

4. If you saw two alpha timberwolves fighting for control of the pack at sunset...you would want the 1dx.

For me, these are the great wildlife photos/moments that I would want to capture because they are so much more interesting and special.....and the 1dx simply does it better.

wonder if you have a bad battery.
I got a loaner from CPS, and took it along a snowshoeing hike yesterday. I had it powered on the whole time, exposed to single digit temperatures - wind chill driven, and powdery snow. The is on the mounted 24-105 was on too.
Took 100 shots or so, and even after checking all the shots later in the comfort of a local bar, the charge was still above 85%
I find the grip ergonomics better than the 1dsmk3 or the 5Dmk2 with grip
Yes, the shutter it's a loud and solid clunk - and 12 fps scares nearby P&S shooters

It's possible.  It was a loaner.  Prior to getting the eval 1dx, I used a 5DIII.  With the grip and two batteries it yields 3600mAH at 7.2V.  LP-E4N for the 1DX is 2450mAH at 11.1V.  Also considering that the 1DX does drive the AF systems faster and likely drains the battery faster than on a 5DIII, I did get used to shooting 1000+ shots before the battery would get anywhere near 50%(about 1 to 2 weeks of shooting +chimping).

Not saying the 1DX has a bad battery life but it does only accept one at a time (it's easy enough to just swap batteries when you need to) not that it even needs to be compared.  Having the two batts in the 5DIII grip is just a convenience more than a practicality.

Ha Ha  - a few weeks ago I had a referee jump for cover when I first started firing the 1DX off behind him at a basketball game - he said he thought it was gunfire . . . glad he wasn't packing . . .
