When taking pictures, can the focus ring and zoom ring of a general camera be adjusted at will? The focus ring of my Nikon D60 seems to be immovable. Is this normal?

Your lens is a D60 kit lens. The focus ring and zoom ring are different things and can be adjusted separately. But the focus ring of your lens cannot be adjusted at will. This lens needs to be in manual focus mode to adjust the focus ring

There is nothing wrong with your camera, this is a problem with the lens:

1. The zoom ring of any lens can be adjusted at any time

2. Some lenses cannot focus manually during auto-focusing. You need to turn the "A/M" switch to "M" to focus manually, but at this time, auto-focusing is no longer possible.

3. Some lenses can also twist the focus ring while auto-focusing, which is called "full-time manual focus"

The D60 kit does not support "full-time manual focus" and you need to turn the "A/M" switch You can manually focus when you reach "M", but autofocus is not possible at this time.
