A Point about Focus

When you auto-focus, do you use one focus point?

You should. That way you, not the camera, determines where sharpest focus is achieved. Wherever that may be.

But you may not know this:

    1. You need light, distance, and a subject (with horizontal/vertical lines) in order for your camera to focus.
    2. Focus points are sensitive to horizontal or vertical lines.
    3. Some, like the point in the middle, is sensitive to both horizontal and vertical lines.
    4. Some cameras have multiple such both0way sensitive focus points.
    5. Some cameras enable more focus points to become both-way sensitive when faster lenses (like those with apertures of f/2.8 or better) are in use.

      Yes, knowing all that technical stuff will make you a better focuser.

      1. if 1 focus is preferable, why would newer cameras always feature their multiple and numerous focus points? wouldnt that just focus for the closest and largest within all those points?
