Can I take pictures in aperture priority mode?

Of course.

You need to understand the weaknesses of this wonderful photoshooting mode and and be able to work around them.

Train yourself to control the shutter speed selected by the camera, and understand the full depth of the concept of depth of field.

After that, Av mode will become extremely convenient and useful.

Most of the time I shoot in Aperture Priority mode because of its convenience and the camera speed it offers.

Despite the fact that shooting in any other mode does not give me any difficulties.
