Meaningfulness of center dot

[capricorn8]

For some cameras (Olympus OM-D, probably other mirrorless cameras as well) the center dot doesn't make sense; it's rather confusing because it suggests that this spot in the image is particularly important in terms of focusing whereas it's not.

In case of Olympus OM-D cameras, the "AF Areas" information is just one of the predefined AF fields. The exact focus point can be anywhere within the rectangle; it is determined by the camera's AF algorithm and its exact position is not available in EXIF data.

Not sure if this is something that can be handled universally by the plugin, in a transparent manner. Maybe it's too complex. Another option would be to make it an option in the plugin whether to use center dots or not. Just as an idea.

(as a quick fix I have commented out this portion in the code I'm using)

Opening this issue was nonsense.

For Olympus/OM cameras, the only useful information related to focus point is AFPointSelected. Drawing a box around this point has no added meaning in terms of focusing, but it helps to recognize / find the point more easily on the image.
Reverting implementation to POINTTYPE_AF_SELECTED_INFOCUS.
