All right, I'm still out shooting, but so far my general observation is if you have the 1D Mark IV, the clear upgrade is the 1D X. If you already have a 5D Mark III, you would not substitute the 1D X for the 5D Mark III. So far I'm not seeing anything difference in regards to IQ. I did a really far crop on one photo out in a field, and the depth of detail stops shorter in the 1D X photo, likely due to the less 4 mp than the 5D Mark III. Well, now this is interesting. Like Brian mentioned, the coloring looks different because I'm thinking the 1D X and 1D4 for that matter, you can even throw in the 1Ds3, seem to be metering more accurately and the colors look a bit more accurate. Sometimes the auto ISO on the 5D3 is slightly off, even though it says the exposure is correct, whereas the 1D X, 1D4, and 1Ds3, are never wrong. Photos to come.
Awesome, thanks for going out of your way to provide your experience, means a great deal!
The metering on my 5d makes me miss the 1-series option to adjust 0 ev on the scale... my 5d3 is usually off by at least one full stop to my liking, always +1 or up to 3 stops up in backlight situations...
Yep. Same thing I noticed. The 5D3 pictures are SHARPER than the 1D4, it's just I have to adjust exposure and color in post. The 1D Mark IV pictures I can literally not even touch the exposure bar and I noticed this with the 1Ds3 and 1DX. That is an excellent point to note! I'm headed out now to do some landscape shots in the afternoon/evening sun, some telephoto shots on distance objects, and then some high ISO night shots indoors. I would like to do a bit more low ISO work, but that may take a day or two to get in those situations. I have a ton of ISO 400 work from yesterday, but that's not really what I wanted; I was hoping for 50-100.
