[QUOTE="Felisek, post: 358030, member: 23887"] [B][SIZE=4]How to check your sensor[/SIZE][/B] 1. Find a large flat surface of bright uniform colour. I use my white ceilings. 2. Set the camera in manual mode and lens in manual focus. 3. Set a small aperture, e.g. f/16 4. Set the shutter speed slow enough to overexpose by about +1 or +2 EV. 5. Point your camera at the surface. Get close to it, but not too close, you don't want a shadow. 6. Focus the lens at infinity, you want to blur out any specs on the surface. 7. Take a picture. You should get a bright uniform smooth area in your picture. You will see any dust specs from the sensor. The small aperture makes them sharper and easier to spot.
