I have an old, used Panasonic LX100 (Point and Shoot) that I plan to use as my main all-use video camera. I just started noticing that dust spots are visible in the image on apertures larger than about 4, and they become sharper as aperture is increased.
I have a couple of questions. First of all, would this indicate that the dust is on one of the lens elements, on the sensor, or either?
Second, if I were to have this commercially repaired, would either repair be substantially harder than the other? I'm keeping cost in mind as I might just get an ND filter to avoid using the higher apertures if the cost is too high for my practicality (at least until I save up to have the repair done).
