  1. THANK YOU! This video helped me a great deal! I was just using the clean function thinking that the camera automatically cleaned the sensor. I didn't know you had to open up the camera and physically clean the sensor. I was cleaning the mirror and the lenses to no avail, but once I used alcohol, the stubborn "dots" on the sensor showed up and I was able to remove them. Now the camera is working perfectly well again.

  2. Tried this on my A77 exactly as done in the video, and eliminated several pesky dust spots instantly!  The combination of auto-cleaning mode and the blower works perfectly.  Thanks so much for posting this quick, simple explanation.

  3. You have to add another step to get at the sensor in the A77. Once you have entered the cleaning mode and powered off the camera you have to flip a little lever at the bottom of the mirror for it to move out of the way to get at the sensor and push the mirror back into place once sensor clean is complete. Hope this helps.

  4. Cheers for this. It is logical to try and blow air into the sensor housing, but hey, then again camera shop asked for 50£ and to send camera over to some shopwork.

    No wonder electronics shops and going bust one after another with scams like that.

  5. Thank you, that was incredibly easy and worked perfectly! Problem is, why the hell didn't I find this BEFORE doing a weeklong roadtrip thru the rocky mountains and having dust ruin all my pics 🙁

  6. @skliau1027 True, though it is harder to blow it facing down. I have not done any tests to prove that facing down is any more effective than facing up (since when I do it facing up, I manage to get rid of all the dust!)

  7. Brilliant. Thanks so much for this. I've had an annoying mark on my photos for ages – it's ruined so many good shots. This has solved the problem. Nice one!

  8. @SeeKnowledgSeekDawah F22 is the aperture. Turn the top dial to "A" (Aperture Priority). Roll front dial so screen says F22.

    F22 means diameter of lens iris is 1/22 of the focal length. For the 18-55mm kit lens set at 18mm and F22, the diameter is 18mm/22 = 0.8mm! If you zoom to 55mm at F22, the diameter is 55mm/22 = 2.5mm.

    F22 reduces light and makes everything in focus, including the dirt that is on the sensor. You can also shoot at F8, but the dirt appears bigger and harder to spot.

  9. @bennazis what is a target mark? Dust on the sensor will not appear in your viewfinder or mirror, unless you have dust on your viewfinder or mirror AND sensor. Go buy a blower.

  10. hye bro..there's a visible dot appear on my target mark…n when i take picture..its appear on the pic ..sometimes the dot is black..sometimes its blur..is it dust?or what?i don't have the blower to clean it up at the moment..and im really worry bout this..help me

  11. @graf636 This is the Sony Alpha 900.

    @donatp93 I tape it up to prevent brand-ist questions like "why not Canon/Nikon?"

    @flakeu True, though it is harder to blow it facing down. I have not done any tests to prove that facing down is any more effective than facing up (since when I do it facing up, I manage to get rid of all the dust!)

  12. @graf636 Alpha A700 as it says CCD in the menu the A850 and A900 Both use Exmor CMOS sensors., with all that black tape on it , it looks a bit misused though.

  13. Thank you very much for posting this informative and direct video Albnok. I had a troublesome speck of dust inside my A200 that I have now managed to remove thanks to your lesson on how to do this..Once again TY

  14. i just got that same style of blower today and i'll be trying out this method on my sony a300 (except when i do it the opening of the camera will be facing down to let the dust fall out).
