It's normal - happens to my M Sport brakes but it doesn't bother me. Happens to my wife's car with single piston sliding calipers as well. Also happened to my previous Nissan 4 piston brakes.
If you want less noise, add brake grease to the sliding pins to provide lubrication. You may need to add some a few times a year as the noise may come back over a period of driving the vehicle in various weather conditions.
