In the long run, I think 100-400 is for me. It’s too big as is....can’t deal with the 200-600 size.
Charlie don't forget the 70-300G, I've got a primo copy and it is def. going on the trip. If it weren't for 'bear camp' I'd only take two lenses
for the trip. Chatting with Fred at FM it would be the 24/1.4 and the 200-600. Only two. Hard to imagine But the bears get close there
and the 70-300 on the Riii for those possible encounters.
