I use the AV wheel on my PZ-1p when I see that I need to change the shutter speed that the camera has selected while maintaining correct exposure. Can I do this with the camera set to Aperture Priority by turning the aperture ring? Certainly I could. My way of shooting when I work fast is to use Program mode. Using the AV wheel gives me control of my shutter speeds without changing modes. I also do not have to take the camera away from my eye to do this. It is very convenient for me. Of course, this is just my way of working. It is certainly not the only way.
