1DX vs 5D3

[bdunbar79]

@bdunbar79: did you get to do the macro shots and the sports shots that you were talking about?
Or did you leave the matter, after deciding on keeping the 1DX'es for the sports shooting 

Actually, I did not leave the matter.  As nightbreath is likely impatient with me as well, I have had nothing but rain and wind here the last 5 days.  I wouldn't think anyone would really value any tests in those situations   Yes I will have ample opportunity this week to shoot outdoors, macro and action, at low ISO.

I wasn't trying to be impatient, just wondering if you left it or not. As written in another thread, I'm considering how the 5D3 works for sports shooting, since getting proper AF for sports is the one point I've had problems with. So any feedback on how the AF tracking performs on the 5D3 is highly appreciated.
If you come back and tell me it stinks and the 1DX rocks, I just have to go and kill myself somewhere quietly

I may be itching to get a new body, but my fingers are not twitching just yet so I don't have a problem waiting a week for your research.

Thanks again.

Well, I can tell you this.  The AF on the 5D Mark III, that I just tested out tonight, is pretty brilliant.  I had it in one shot and was shooting water drops hitting water with green food coloring in it.  The cup with watter under the faucet was pretty much in the dark, as I was using a flash and the AF still nailed the edge of the cup/water edge at the brim of the cup.  So at least we know it focuses brilliantly in very low light.  Obviously I didn't need it in AI Servo, so that'll yet to be seen.

This was the shot I was speaking of; AF in near dark conditions, 600EX-RT at 1/8000second, f/4.  Since I couldn't see very well, I doubt I was focused where the drop hit.

[bdunbar79]

This one may have focused on the drop area a bit better.  Again, I couldn't see well at all, but at least the AF found something and locked, unlike the 5D Mark II.

Dang, had to go and get some paper to swipe the floor from my salivation  And my fingers are starting to twitch now!

The af maybe similar, but the abillity to lock and track isn't... the 1d is soo damn fast and accurate I'm locking and tracking and shooting pictures I never could, even with the 5d3.. and to swap to vertical and have the buttons identical to horizontal is fantastic !!

Noisewise I use 2500 the same way I used 1250 on the 5d3...

I was not able to do any comparison since these photos are not keepers.  I was just curious as to how well the 5D3 could focus in very low light.  To give you an idea, I had my flash set to the right and ISO was still 8000.  The only real way to know is to take both cameras to a sporting event indoors and shoot AI Servo and get a feel for it.  Although I agree, the 1DX focusing is amazing.  The focusing on the 5D3 is tremendously better than the 5D2.

I will do this experiment again.  Next time I will have a portable light on one side at least, and fill flash on the part of the sink that is more vacant.  Manual focus where the drop will hit, and do a 6 fps burst on the 5D3 and 12fps burst on the 1DX.  It will be fun to see if there are any additional parts of the splash recorded by the 1DX vs the 5D3.

I'm reading confusing things, but does anyone happen to know if I can get the focusing screen that shows true dof faster than 2,5 for the 1d X?

Think it was EG-S for the 5d mkII.
