I was just experimenting with the camera in Manual mode to learn how to use it. I adjusted the settings & then pointed at the sky. There was an arc type thing in the lower middle slightly to the right in the photo (it is above "lower part" in the title). This happened no matter where I pointed in the sky & the arc was in the same spot. I took some pics inside too and the same thing was there.
Update: Seems as though there was something on the sensor. I took it to the shop where I bought it and they used an air blower to get it out for me.
