Hello, I suggest to change the first one to Auto-Servo AF. From the manual:
Auto-Servo AF: Camera automatically selects single-servo autofocus if subject is stationary, continuous-servo autofocus if subject is moving.
Be aware that in the Single Point AF mode, the user must select a focus point. It is easy to make a fault here and set the focus point with the cursors to the upper left without that one is aware of that. Check in the info display where your focus point is. See the red area in the screenshot.
Try to change the AF mode to Auto-Area AF, where the camera automatically detects subject and selects focus point.
A question: are all your photos “not clear enough” or just some?
Another suggestion. You say that this is your first digital reflex. That’s not the same as using a compact camera, it’s a bit more complex because you have more possibilities to adjust things. But a very beginner-friendly mode is the Program mode (that’s the P on the PSAM dial). In that mode the camera takes many decisions for you, you only have to frame and hold the camera tight when you take a photo.
Good luck!
