This will be my first deployment with a DSLR. I am very excited to drag it along with me, but a little unsure of what I want to bring. I know the body will be my 5D3, and I'll have the 70-200 2.8 along with me. Ideally this will all fit in a Pelican 1500 case, because I can't promise that it will be in the best of environments, and I know how these "trips" work. It leaves me room for 1 medium size lens. Knowing I'm headed to one of the more God-forsaken corners of the globe, weatherproofing I would think would be a big plus, but I'm not sure if its a necessity. I was thinking along the lines of Canons 24-70 2.8 V1, Tamrons 24-70 2.8, Canons 16-35 4. I'd like to stay as cheap as possible because of the possibility this equipment may not survive. Anyone on here ever drag a DSLR around in the type of environment where they had to carry everything or had limited room, and may or may not have to jump it out of a helicopter? Any input is appreciated. Thanks in advance!
