Hi everybody!
I just bought my new Canon A700 and I observed that when shooting night
or low light photos with flash, orbs appear on them (one brighter than the other
2 or 3 in the same photo).
Is this a problem with the camera (dust inside)? The lens is not removable...
Anyone having the same problem with this camera model?

I assume that you see these orbs only when you use the on-camera flash and the number and position of these orbs changes completely from shot to shot.

This is really a common problem when shooting with on-board flash. Each orb represents a large particle of dust that has been caught in the light blast from the flash and has been imaged very out-of-focus because it is so near the lens. Separating the flash from the camera lens helps reduce this problem a lot because the stuff caught in the light of the flash is no longer within the lens' field of view unless is is so far away as to be practically invisible. Shooting without the on-board flash can also help a lot, as can shooting in less dusty conditions if that sort of thing is under your control.
