I have owned one sony a55 and two sonys a65 and all 3 of these cameras have had dust or dirt that would show on the photos when it was first used and brand new. These dirt spots have nothing to do with the lens because the spots are there with different lens. The spots are more pronounced when I am zooming in. Recently the spots have gotten worse as can be seen in the photo. I live outside of the U.S. and took the camera to be cleaned by an authorized Sony dealer and the stains were actually worse afterwards. Does anyone have any suggestions what this could be and how to clean it? Do I need to buy a new part?
Thanks for any help.
Certainly dust on the sensor. Surprised the Sony repair could not get it very clean, not that it would stay that way, but it should come back with at most a few small spots.
Step one, change lenses in a clean environment if possible, keeping the lens opening facing down.
Step two, get a blower with a filter built in like the Rocket Blower, blow off the mirror then raise it, push small button at base of mirror, while pointing the camera down, blow off the sensor. Try to stay away from freon type sprays as the liquid can stick to the mirror and sensor if you are not careful. There are CO2 blowers but you are not likely to run across one in normal camera stores.
Step three, use a lens pen to remove isolated small specks of dust, these sometimes come with the blowers and are meant to pick-up small dust particles. Do not use on mirror just sensor. This is as far as I have ever gone.
Step four, is a wet clean, kits available from various sources I have not done this yet, but a search on this forum should give you a lot of discussions on various ones available and how to use them.
