 p.31 #11 · RG on 1D Mk IV autofocus performance | |

Anybody ever considered the obviously remote possibility that RG actually knows how to set-up a 1D type camera, after having worked closely with Canon engineers on numerous occasions, field-testing the MkIII? If he weren't capable of making sound decisions re. AF settings, Canon would have either taught him the basics or would have ignored him completely, but they kept on coming back to him. Hey, it's just a thought...
There are already in this thread enough arguments that have cycled back around at least once, and I don't want to get sucked into one that's about who can set up a camera or not. I tried before to express great respect for RG; I think much of the ad hominem stuff directed at him in this thread is crap. I am sure he can set up a camera. And I mean no disrespect to him when I say I am sure I can set up a camera, too.
All I can go by is his report, which says:
We figured out early on that to get the camera to track as best it can, the EOS-1D Mark IV must be configured to use multiple AF points. This is a departure from any previous Canon 1-series SLR we've used. For example, if the camera is set to use a single AF point alone, the number of in-focus frames can be considerably lower than we've described in this article (for lower light tracking in particular it can be a wipeout). In addition, the frequency with which the camera will frontfocus increases and the camera's 10 fps frame rate will constantly slow, and slow dramatically, as the AF system struggles to detect subject distance.
In our testing, enabling C.Fn III-8-1 (Left/Right AF point), made no discernible difference, C.Fn III-8-3 (All 45 Points Area) was impossible to use for sports because the AF point jumps around continually (in other words, this setting is meant for another purpose) while C.Fn III-8-2 (Surrounding AF Points) brought a noticeable improvement in both AF system feel and the number of in-focus pictures. While the frame rate still slows down a fair bit, it's not as big a drop and it doesn't drop as often as when this option is disabled (this behaviour is linked to the Custom Function discussed next).
All but a handful of the downloadable pictures were taken with C.Fn III-8-2 (Surrounding AF Points) turned on.

So, unless I'm reading it wrong, he/they did some work on tracking and came up with settings that they used in all shooting situations with very few exceptions. I don't think that's the best use of this system and the flexibility it offers you, and that it invites some (not all) of the results he got. I sure as heck am going to be changing settings when I leave the soccer pitch and head out to the motocross track, and in fact several times at the track in different situations, because there are going to be different situations where optimal performance calls for different settings.
With almost a thousand frames through my MkIV in the last week, which I'm sure pales to the number of shots by two men with five cameras on a mission, all testing and almost all on soccer indoors and out, I'm certainly not of the impression that "The EOS-1D Mark IV's autofocus performance through [with] soccer was bizarre." The observations I made were to offer a perspective that is entirely aimed at offering additional information to help understand or use the camera, for what those observations are worth. If people want to make that a credibility test between RG's set up abilities and those of generic Fred Miranda drone shooter, then I guess I need to expect less of the board.
