category Cameras • hashtags Canon, 7D, Auto-Focus • 1 min read

The AI Servo tracking sensitivity is set with the C.Fn III-1 setting. I wrote about it in: C.Fn III -1 AI Servo Tracking Sensitivity. Its purpose is to direct the Canon 7D on how fast it should switch focus, when something come in front of your subject.

My own setting used to be to setting to:

Slower than medium, but faster than slow

This is a good …

Canon 7D: Automatic 19 Points Select Focus Point

category Cameras • hashtags Canon, 7D, Auto-Focus • 1 min read

This is the most maligned focus point selection system. Everybody says how useless it is. It’s the default mode for Canon. Can’t be that bad if Canon sets it as the default, unless Canon wanted to sabotage the millions of dollars spent developing the 7D. The focusing area cover over 60% of the viewfinder with very few gaps.

  • In One-Shot AF Mode, the Canon 7D will focus on …

category Cameras • hashtags Canon, 7D, Auto-Focus • 1 min read

The Zone AF is very similar to the automatic 19 points select focus point, except for the smaller area in the focusing matrix. The Canon 7D will selected the closest focus point with enough contrast.

There are 5 zones:

  • The center zone with 9 points
  • The top zone with 4 points
  • The bottom zone with 4 points
  • The left zone with 4 points
  • The right zone with 4 points
  • Contrarily …

Canon 7D: AF Point Expansion

category Cameras • hashtags Canon, 7D, Auto-Focus • 1 min read

The AF point expansion is one of the trickiest focus point selection on the Canon 7D. It’s for the AI Servo mode.

  1. The AF point expansion starts in the regular single AF point.
  2. As long as there’s enough contrast/detail at that point, the focus will stay there.
  3. If the selected point loses the contrast/detail, the Canon 7D will interrogate the points immediately around it. Do you …

Canon 7D: Single Point AF

category Cameras • hashtags Canon, 7D, Auto-Focus • 1 min read

Talk to anybody who’s claims to be an “expert” in photography / Canon 7D and when you ask any question about focusing you’ll be told that if you knew what you were doing, you’d be using the single point auto-focus mode.

You can select anyone of the 19 points with the joystick and use the single point auto-focus in either One Shot or in AI Servo.

Canon 7D: Spot AF

category Cameras • hashtags Canon, 7D, Auto-Focus • 1 min read

Some people claim the Spot AF is the “holy grail” of the focusing on the Canon 7D. That’s because the area is so small, that you can decide were the focus will be. The spot AF is available on all the 19 points. Every point can be selected with the joystick.

When selecting the Spot AF, the display shows a small box inside the regular focus point. And that …

Canon 7D: Orientation Linked AF Point

category Cameras • hashtags Canon, 7D, Auto-Focus • 2 min read

After a long analysis of my photos through Lightroom, horizontal/landscape vs vertical/portrait. I’ve found that I need to change my focus point in the vertical mode. I’ve always known about the Orientation Linked AF Point, but I’ve never bothered with it.

What a mistake! It’s great, so much faster and so much better than doing by hand by selecting the AF point manually. The …

Canon 7D: C.Fn III - 1 AI Servo Tracking Sensitivity

category Cameras • hashtags Canon, 7D, Auto-Focus • 2 min read

This setting is not what any “normal” person would think. It’s not about how quick the focus tracking is, it’s about what happens when there’s an interruption in the subject being tracked. What happens if something/somebody comes in front of the subject you are tracking? Does the autofocus keeps on tracking the old subject and tries to regain it or does it tries to focus on …
