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.
