The camera has one problem, spontaneous activation of the dial buttons. Sometimes it helps to flip up and down the display, press the playback button several times or press the self-timer button, at times you need to turn off and on the power. If the problem recedes the camera is working properly, the touch screen works, the photos are good, please take a look at sample photos taken with this camera, last 4. External speedlight works and is a part of the set.
