Taking care of your Digital SLR camera sensor against dust

1. If you swap lenses, try to do it in a clean area where there is very little dust.

2. Try to swap lenses less fequently (buy an all purpose lens e.g. 28-300mm) etc.

3. Clean the sensor with blower, cleaning set (or even sticky tape (be carefull and read a lot about it in forums before applying)

Also a little dust doesn't have to be a real problem. A single speck can be cloned out in the picture using software, however it does eventually becomes annoying and cleaning is the only alternative.

Overall, there should not be a big issue.
