Auto Focus

[iND]

I still like the single shot / single point auto focus.
It is VERY accurate in low light situations.
The 61 points have 41 non blinking cross points that are very sharp, I have tried the center as well as the peripheral points.
I do not find the autofocus screen a problem, the points are red for selection then turn black, does not seem to be an issue even in low light.


I also HIGHLY RECOMMEND to set the AF POINT DISPLAY to ENABLE to allow the AF POINT to show on playback, this will allow you to check the area that was hit for the autofocus, I find this much more reliable than trying to determine focus on the screen, this is like my focus histogram.


I am also interested in some opinion on separating the AF function from the shutter button (a feature of 1Dx and 5DIII), I am tempted to make this setting but would like some input from other users.

Thank you

Be careful... the AF Display shows which point was active, but not necessarily the spot that the camera focused on. That is, if your center point grabbed the eye of your subject, but you recomposed or moved a little after focus was acquired, then the focus point is going to be displayed on the playback wherever it was when the shot was taken... not necessarily were it focused. So if the center point was on the eye when you focused, but was over the nose when the shot was taken; then the display would show the focus point on the nose even though the actual focus was on the eye. This can be deceiving.

You probably already knew that, but there have been some that have been confused by this thinking the camera focused as displayed when in actuality they were forcused on something completely different.
