A co-worker is insisting I take his D700/14-24/24-70 on a trip to Blackwater Falls, WV for the weekend (I'm in the southern tip of Texas). It's free. The answer isn't as obvious as it would seem. My pack holds a D80/16-85 as the main camera, and an FE2, primes, plus film for backup. Thiand primes ng is, I sort of know what I'm doing with the D80, and really know with the FE2. The goal is fine art photography of the falls in Blackwater State Park, a lot of rugged hiking in the side canyons. I know the D700 and lenses has IQ far beyond that of my two antiquated cameras, but I've never used one before. It means a heavier backpack and tripod (would have to bring the Manfrotto instead of the Slik Sprint). The FE2 would stay behind, replaced by the D700. Besides the liability for a system that's not mine, would I be losing in IQ for not having experience with the system? I'm thinking of accepting, but not taking the 14-24. I can see waterfall spray getting all over that $2,000 lens. What would you do? I'm leaving in four days so have to decide quick.
