If the replacement of the lens is due to the
sapphire window being cracked (this will take
a considerable impact) then it is important to
make sure that any moisture inside the lens
cavity is removed. It is important that the lens
cavity is cleaned only with a cotton-bud
dipped in Isolpropyl Alcohol (IPA) as other
cleaning agents may mark the glass face of
the CMOS sensor.
In all cases clean the thread area, as this will
probably have an amount of debris build-up.
Always ensure that the threads and sensor
glass is perfectly clean and dust-free before
re-assembly.
Remove the new lens from the packaging and
clean the rear element with a lint-free cloth
that is suitable for optical cleaning (spectacle
cleaning cloth).
Ensure that the two black ‘O’ rings are
greased, if necessary rub some silicon grease
