As I am sure there are a number of underwater photographers that also end up carrying a large topside lens. I am curious as to your experiences as you travel with it. Lenses like 300mm, 400mm 500mm. Some of these or all come with their own specialized carrying case/suitcase.
Do you carry it on or check it?
If you check it how do you pack it?
If you carry it on what are your airline experiences like?
Interested in your experiences and insights.
Cheers
Todd
