Hi Samir2199,
I'm sorry to hear you are seeing Err80 on your camera. That is shown when the camera either detects an electrical malfunction in the camera, or an issue with writing or reading files from the memory card. There are somethings to check with that error.
The first thing is to try loading a different battery in the camera. Sometimes if a battery is malfunctioning and over or under powering the camera it can cause that error. If the issue continues the next step would be to load a different memory card in the camera. Sometimes if a memory card is malfunctioning it can cause that error. If you still see the error at that point the last thing would be to attach a different lens. Sometimes if a lens has a short in it that error can be shown. Swapping out each piece one at a time would help narrow down what piece may be the cause.
If the error continues showing after swapping out all of those pieces at that point we would recommend sending the camera in for repair.
