Silly thing No.1
Dust on the sensor.
There is a worry for many about the dust that will eventually appear on the sensor. Many of the new DSLRs will have a self cleaning facility built into the camera. If this fails, i recommend a tried and tested method, use an air blower. Before you rush out and purchase all the sensor cleaning swabs and liquid, or miracle brushes, purchase yourself a reasonable priced air blower like Giottos Q.Ball. I stupidly saw dust on my sensor, panicked, and purchased a load of cleaning equipment i have not yet used. I have been using DSLRs for the last few years, owned two DSLRs and have not had to touch the sensor. Just follow your camera’s instructions for cleaning the sensor (this will involve exposing the sensor), give it a good blow, and check. Nine times out of ten, you will not have to touch a thing. Ten out of ten for me, so far….
Stay tuned for tip number 2.

Adrian Rachele,
€150 seems rather excessive for a sensor clean. Warehouse express here in the UK have a service that is £50 (€65). The Giotto Q.Ball is rather cheaper also. £8.99 on Warehouse Express website, which should be around €12. Click here for a link.
When they clean the sensor they will blow it first, and then give the sensor a clean with special chemicals and tools. You can purchase these and clean them yourself. I purchased items from Photographic Solutions. Click here for the website. They have a good reputation and you can find tips on how to clean and use these products on Youtube.
But as stated, give it a good blow with the q.ball first, and see if that solves your problem. If not, then decide if you want it cleaned professionally or do it yourself.
