回答“Tiny spots on my pictures. Any ideas?”This looks an awful lot like dust of some sort. This prevalent and evenly spread out is very peculiar, though. Do the specks always appear in the exact same location between shots? Does the size decrease and sharpness increase as you stop down? If the answer to both is yes it's most likely something in front of the sensor. Similar physics apply between the sensor and the aperture as to bokeh. If dirt is on the sensor it's not in focus because of the low pass filter, the actual obstruction is just a few millimetres in front of the sensor. Anyway, if it is dirt of some kind, and having your camera cleaned hasn't fixed it the only solution would be a new sensor and/or low pass filter. Kind regards, -Kal Update: I chatted with a chap from a photostore and he thought it might be oil. Some other cameras had oil dripping from the shutter and ending up on the sensor. To clean that off youll need a swab and do a 'wet cleaning'. Maybe no new sensor after all!
