Conclusion: I use the 1DX for weddings as a replacement for my 5DII. Pros: The AF is responsive and fast in good light, and AI Servo tracks relentlessly. I can even use the 85/1.2 lens to track slow moving people, like the bride coming down the aisle. 12 fps is blazing fast.
Pros: Quick Start-up time, good battery life, Nice features/settings, excellent image quality, Superior build quality, Bright LCD, usable images up to iso 12800, fast and responsive af in good light, longer battery life than 5dii, 12 fps very fast, two cf card slots, ability to control speedlites in th...
Cons: heavy, af freezes, playback button freezes, ai servo slow in low light, off-center af points less sensitive in low light, af points are grayed out

Conclusion: The good: it's clear it's the best camera Canon has when it comes to image quality, low light, autofocus...you name it. It's a technological marvel. The bad: Every six months this camera seems to develop a fault that requires a return for repairs.
Summary: Try (suggest rental for a good few day' workouts) before you buy. Compare others - esp at price. Disappoimted with IQ compared with my eight year old 1Ds Mk 2.Love the speed and wide range of focus options. Love the strength and well-used to the weight.
Pros: Bright LCD, Comfortable Controls, Fast Shutter Speed, Focussing, Speed, Strength Solidity, Strong Construction, Vertical Integral Grip
Cons: Iq Reviews Not Delivered, More Grain Than Expected, Poor In Low Light
Conclusion: Absolutely outstanding camera in terms of IQ, AF and overall speed - it's weakness however is it's inability to focus in low-light using Ai Servo. Be warned: if you are having trouble locking onto subjects in low light (iso 12K f4 1/50th territory) use any fps between 1 and 10 and You will be fine,...
