I have some Tamron and Canon lenses a few years old that look like they need cleaning (inside and out).
They are in good condition and not dirty (always keep the caps on when not in use). But have some very light spots on the inside of the lens.
I also have some DSLR aps-c cameras and the sensors look perfect.
Should I care?
Where can I find some small simple place that can take the lenses apart and do basic cleaning/lubing?
I have been using a dry cabinet ~ 45rh
