My XS is about 2 months old and all of a sudden the autofocus on my 18-55mm lens won't work. The red light blinks when the shutter button is pressed halfway, but it won't take a picture. It will take a picture on MF. I tried my new 50-250 lens and it will take a picture using AF. So does this mean there is a problem specifically with the 18-55 lens, or could it be a problem with the camera? I tried doing a search for ideas and it was suggested to recharge the battery even if it looks like it's charged. So I'm doing that now. Any other ideas?
