So glad I decided to take my Air 2S along on this trip to Greece. It's small enough to parcel out into my carry on. No hassles through security at all. Managed to get quite a bit of flying in without getting too much stink eye from my wife or anyone on the ground! I also did a lot of experimenting with filters. When the sun is higher making the water is super blue it's insanely bright so I ended up using the ND16/PL the most.
