Depends on where I go.
Gone were the days where I carry a backpack with like 5 lens a dslr and a tripod - easily 7 kg carry on photo equipments.
Nowaday, I uss mirrorless. Usually, I would bring a 28 mm and a 50 mm full frame equivalent. Or if there is more landscape opportunity, I might take a 16-35 only. I use this setup for places like Taiwan, Europe, Hong Kong, turkey etc. basically just shoot what I can with the set up and not worried about changing lens for every scene and spend more quality time with love ones and enjoy my holiday.
Though a trip to the safari would mean carrying along a Heavy long lens
