Wow... looks like a long walk to get up there, what an awesome breathtaking place!
A lot of people overlook the E16 pancake... it might not be the best lens out there, but for it's price it delivers a lot of bang for the buck, especially in situations like that. I can't think of any current AF lens in that focal that's under a thousand bucks.
Are you using a Windows based computer for your pp, lapdog99? From my mac monitor, the images appear quite purplish... I'm aware there's a gamma difference between the two systems and I may not be seeing what you're seeing.
Humm, the gray clouds do appear purplish, and it is noticeable on the jpegs out of the camera as well. I have to double check all the NEX controls because it is easy to leave some of the settings in creative, etc. my Nikonhotos didn't show the purplish cast.
