Hi There,
so, we have a family holiday planned to the USA. 5 weeks hitting SF, LA, Grand Canyon, Boston, New York and Washington.

My big dilemma is what to take. I have a camera backpack which i think meets all the carry on a personal bag requirements. So i can take a lot but do i need it all. It is a family holiday and so less time for just going out to shoot rather than taking holiday photos. but i want to do a bit of both. The grand canyon is a short stay but i hope to get some nice photos. weather permitting.
Oh and we're going end of next week. so winter and cold.
My kit and hence choices are.
Nikon D750 (tick)
Tamron 90mm Macro
Tamron 15-30mm F2.8
Tamron 70-200mm F2.8
Sigma 150-600mm
Nikon 50mm F1.8

I think the 15-30 is a must for city panorama and Grand Canyon vistas.
50mm 1.8 because its small and good for inside low light.

the 90mm is quite small and light and i think could be useful for a short telephoto.

But i am leaning towards not taking the 150-600. its big and i am trying to see where i might have need. And i could just take the 70-200.

thoughts and experience advice would be welcome.

cheers
