For a week in Scotland earlier this year it was a Nikon F80 and Nikkors (28-105, 70-300, 50mm f1.8), Mamiya C330S (80mm, 55mm, 180mm), Rollei 35 Tessar, Pentax Spotmeter V, Westonmaster and a Manfrotto 055 ProB. Everything got used except for the fast fifty.
Via air... Yesssss, well...
I was going to France this year, then the insanity broke out. I simply refuse to put my cameras in checked baggage, so I cancelled the trip.
The channel-hoppers they use for those trips restrict you to 10 kilos anyway, so when I finally head over there I'll have to pick and choose.
