I have a bit of inside info on this subject, can't really say too much but they're "resolving the issue of how to alter the test so that the 1d X doesn't beat the D4"

I'll just give a quick summary, so as not to create any panic here. I believe the reason the 5D, 5DII, and 7D acquired focus lock on the low contrast, low light, "stationary" towel in AI Servo was because they have a slower frame rate (the 7D lowers its frame rate automatically in low light) which seems to put the emphasis on focus acquisition. The 7D, MKIV, 1DX also have the default feature for first Image focus priority, which also places an emphasis on slower focusing, as opposed to shutter release. We're not yet saying that the 1DX doesn't track well in AI Servo, we're just saying that the first focus lock of a stationary or slow moving subject in low light, low contrast situations is difficult to lock-on when higher than 10fps are in use.
Keep in mind though that when the frame rates of the MKIV and 1DX were lowered they did perform better than the 7D in my testing. I don't own the 5D or 5DII, so I'm going by others findings with regards to this. In case people didn't read the whole thread, at least in my test, these findings were occurring in low light, low contrast situations of a stationary object in AI Servo in order to lock on the target prior to it moving, to establish focus lock so that the camera will be ready to begin tracking once the subject started to move. Sycotek wanted to test the threshold limits of the 1DX's ability.
"I will say though, that in my experience in real world shooting with the MKIV, in low light, low contrast situations, and shooting at 10fps, I have never had a problem in AI Servo mode, and the 1Dx seemed to perform similarly under the testing conditions above, however, I haven't had a chance to test it in game situations yet.
Recommendations would be if the MKIV or 1DX couldn't lock on the first frame of a tracking burst in AI servo, then the shooter needs to make sure that they grab an edge of the subject to create more contrast (I do believe that this is common knowledge at this level) for focus lock, once the subject starts "moving" and the distance to the camera increases or decreases rapidly then this is supposed to aid the camera in AI Servo tracking. The other point here, would be to lower the fps to less than 10fps if a problem did arise in real world shooting situations.
I think a good analogy would be if you had 2 race cars going through a slalom course, lets say that one car was limited to 50mph (7D) and the other car was limited to 100mph (1DX). The drivers were told to make it through the course and around the cones as fast as they can without hitting any cones. The 50mph car would have the same chance as not hitting any cones as the 100mph car, because it's up to the drivers to not exceed the limits of the cars. Just because the one driver can go 100mph, doesn't mean he should. He also has the option of going 50mph, or he can go 75mph and win the challenge, or he go 100mph and drive off of the course.
Viggo, in further response to your concern, I don't think that this is as alarming as you think, because the 1DX can be slowed down to meet the needs of the shooting conditions, just because the 5D, 5DII, and 7D are already slowed down by default doesn't necessarily make them better. I would also be curious to see how the 5DIII behaved, however, I expect that it would behave similarly to the 1DX would if we were to reduce the fps of the 1DX to match the frame rate of the 5DIII.
We also have to be careful when analyzing focus points on the monitor or LCD, because if the camera were to miss focus on the center low contrast point of a subject while holding down the focus button, and then we were to re-compose the shot to the edge of the target, the focus points may look like they were focusing on the higher contrast edge the entire time.
I really like the 135mm f/2.0L, however, I don't use it as much as I used to because it is starting to show its age. The lens isn't much faster focusing than the 85mm f/1.2L II (feels like it has slowed down over a few years) and I think the focusing speed needs to be improved to keep up with the 1DX. 135mm is one my favorite focal lengths for basketball so I'm looking forward to a new model. I don't need the extra 1/3 stop of light or IS but will happily take any improvements I can get my hands on.
Do you have problem trying to select the AF point with the multi-controller? It's not responsive with my 1Dx. Let me know if you have the same problem. I'm wondering if it's just my 1Dx or it's the same with all 1Dx
I can't say I have that issue - however You need to enable it - if you haven't then turn the unit on - hit [Q], custom config, select multicontroller (bottom right) and set it to af selector.
Hello again from Archangel72
Here is another nice review of Canon EOS 1Dx from world-renowned wildlife photographer (and Nikon shooter) Andy Rouse.
Amazing pictures !!!
Can't wait for my piece of 1Dx beauty.
Almost there, almost there ...
+10! I expose to my liking, if a stupid Sekonic plastic box tells me it was over I throw it away.. Hm, oh, that's right, I in fact did that with mine after three days of using it...Let's not beat around the bush. It IS overexposed. Justifying that by saying you like bright images doesn't alter the fact that you went to all that trouble and got it wrong.
No problem though, you learnt for next time.
No, it's not. Haha, the very idea that exposure is a set rule and that it belongs dead in the center is a joke, so don't try to sell me such fabricated nonsense. It's exposed perfectly for the desired effect. If you believe that is too much, then I'm happy that you feel it's too much, however it was decided ahead of time, it was edited and shot as such, and published as such.
It's exactly how it was meant to be. The only thing that was "learnt" (not actually a word, by the way) was that I should bring more water for next time.
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.
I am interested to hear from anyone who has used both cameras. I have two 5D3s and I am a wedding photographer. I love my cameras but I am always curious if there is something better that will help me do my job better. I am interested if the AF is just a little faster and better and I have also read that the sensor may be a little better. Anyone have any experience with the two cameras?The focusing on the 1DX is faster and sharper. Only
By a 15% or so. Nothing major but noticeable.
I tested both with the same lightning setup and the same 24-70
Also, listening to the machine gun-like sound of 12fps is
Amazing. Even the sound of the shutter is clean and sturdy. The old 5D II sounded horrible. I
Love the sound of the 1D X
The best advantage of the 1D X is the ergonomics and feel. Even with the grip, the 5D doesn't feel as sturdy and comfortable, but with the extra 4MP and $3000 price
Difference, the 5D is the clear choice.
