Horizontal and vertical lines and autofocus

So if you are photographing a house, the camera will focus more on the front door? Or doors and windows that are vertical across your field of view? Trying to visualize real life examples of this. Thanks!
Roger's example is an excellent one. In landscape orientation, If you're using the small focus box the camera will have much more difficulty focusing on a horizontal branch than on a vertical branch.

If you're trying to focus on the moon in landscape orientation, focus on a vertical edge, not at the top.

I've not tried it, but I suspect the camera doesn't focus well on an ocean horizon in landscape orientation, but if you rotate it 90 degrees it'll do nicely
That correct Sherm. If I have difficulty finding focus with a seascape, I often find that by rotating the camera 90 degrees the autofocus more easily focuses on the horizon, then I half press the button and recompose.

Thank you. Good to hear. FWIW I think you can rotate far less than 90 degrees and achieve focus.

iZoom did okay here - only way I get the craters - horizontal vs vertical attached; the top row of craters look slightly different depending.....Thank you, Sherman!
