Hey guys,
While I was checking to see if my Sony A55 is working fine in preparation for an overseas trip, I switched to a low aperture (f22) and took images on a white background. Noticed after that there were a couple of black dots on the image, some pretty obvious, some slightly fainter. I tried removing the lens and lifting the mirror up to blow off any dust lying around the image sensor. However, despite doing this for several times, the black dots still remain. Question is, does this call for servicing? If yes, do I bring it to a Sony Service Centre or can I just bring it down to a shop like Cathay Photo? Can anyone please advise what's the charges like?
Also, if there're dust specks on my UV Filter, can I just use a micro fibre cloth to clean it off? To clarify as well, I recall reading somewhere that little scratches on the UV Filter doesn't really affect the image cause it's just supposed to control the amount of light entering? (Correct me if I'm wrong please)
Thanks in advance for your help!
