I believe we learned this about the time the NLs were announced, though it may have started before, as a running change. Didn't Swaro say they were looking for a more environmentally friendly substitute? Do we know anything more? Might they have instituted a change and its now on again?Regarding fogging issue, I would like to mention my experience as well. I have an NL 8x42 and Habicht GA 10x40, both made in 2022. I have never experienced fogging issue with NL, even with winged eyecups. However, the use of Habichts with winged eyecups is impossible due to fogging issue. It might be a problem because of their short eye relief as well. It seems Swarovski removed hydrophobic coating from all of their products.
