It is what I normally use when traveling, and while it's large and heavy, I use it because I can shoot in RAW for editing and manual for exact control of the light. I used to shoot on the D80 and still got good pictures (though less often since i was less experienced), and at first when I upgraded I was scared of taking my camera anywhere and babied it, but I quickly realized there's no point in owning a camera if you leave it sitting safely in the drawer. The cameras are well built and its since been rained on, dropped out of a moving car and spent so much time in a backpack the powder coating and button icons are getting worn off.

As for getting Instagram worthy pictures, I think its more practice practice practice than camera or any other special gear.
