I just checked. My Canon will blink red to indicate which exposure spot is active in the viewfinder, but that definitely does not indicate an exposure lock. It is quite possible to get that blink even though the camera is not focused at all.

Yes of course. But it blinks and beeps when you have AF lock.

You can get that blink even if auto focus is off, and even if it's not focused at all. I strongly suspect user error.

You can't take a photo in One Shot when you don't have focus lock.

I think you need to just read the manual and practice a bit to make sure you know how to use it.

I downloaded the first picture, with the brick building. Unfortunately, the image is so strongly compressed that I could not diagnose the problem with any certainty.

Nonsense. You do not understand JPEG compression, it does not cause such unsharpness.

Compression artifacts seem about equal to the image blur.

No.

The compression artifacts are so severe that I think that compression is a big part of the problem, but I think the image is also very out of focus. I suggest that you store your images at the highest quality.
