How to Prevent condensing lens. When the lens is moved from hot to cold space or vice versa , there is
the possibility of the lens will have condensation or dewy .
A common example is when we get out of the car air- conditioned chill out hot car . Or conversely , when we carry out our camera and lens from a warm place like home to outdoor cooler and moist .
The meeting between the camera and lens are warm to a cool place will
make the water vapor condenses into dew and sticking on the surface and
inside the camera lens .
If allowed to go or repeated , this condensation can cause mildew , rust and even shorting .
How to avoid it is to enter the camera and lens into an airtight
plastic / ziplock , and then let the camera and lens to adjust slowly to
the new temperature .
It should be about 10-20 minutes to adjust depending on the length of the lens . Simple and short lenses like the 50mm prime lens or a zoom 18 - 55mm takes less time to adjust to the new temperature .
If
you already condensing / condensing , do not remove the lens from the
camera and insert the camera and lens in plastic and try to remove the
air from the plastic . Incorporating water absorbent such as silica or rice can also help .
Do not worry and wait until the camera adjusts to the ambient air . In some cases , need to wait 1-2 days to recover the camera and lens to normal .
