I am pretty sure I have dust inside of my Sony a55 SLT (Single Lens Translucent). However I'm not sure how to get rid of it or where exactly it is. I think it could be either on the translucent mirror or the sensor itself. It's in the same place each time, but mostly occurs on images with a high f number (e.g. F22 etc)
An example image (cropped):
Would a general sensor cleaning kit remove the dust form the translucent mirror part?
I'm unsure of what to do as it's not a conventional mirror like in SLR cameras.
Any recommendations on a good cleaning kit? To be honest I'm slightly scared about it all as I don't want to destroy my camera!
