Sony mirrorless a5100 lens issue, Condensation!?

[caddy31389 0]

Hi,

I’m wondering if anyone has the issue with the Sony mirrorles camera. I have a Sony a5100 with a 16mm pancake lens and the ultra wide converter for tandem photos. I’m shooting in New Zealand so temperatures at 15000 feet can be -20.

I am getting a very subtle small faded patch in the centre of the photos in free fall. I took it to the local camera shop and as it's forming from the inside of the photo he thinks its condensation. Apparently as it’s a 2 peace lens the air trapped in the middle is causing it.

Anyone else had this issue and know of a way to fix it?

I have uploaded some photos.

You could try putting the lens in a zip lock bag with some silica gel packets.
When photographing in the winter I put the camera in a plastic bag before going inside, and keep it in there until it's warmed up again. Avoids the warm air condensating immediately on the cold glass.
