I'm slowly getting into wildlife photography. I like the idea shooting with 2 bodies - just to avoid lens changing on the field. Well, I think most of us already know, the weights of carrying two bodies with BIG white lenses.
As I don't think wildlife always means carrying tons of gear around and machine-gun photo the unsuspecting animals, I try to keep it light... and I fortunately don't have the funds for such gear in any case so that 6d+100L & 60d+70-300L is the max weight I could carry.
I try to predict what I'll encounter though as I feel carrying just one camera lets me move more naturally which is always good for health as it prevents repetitive movements and forced body positions.
May all gods in this world and Lord Buddha blessing all of my dear friends in CR, to have a great helath and get all the good wishes that you want in this Valentine day and beyond.
Oh my, Valentine's day (and probably Halloween) have joined up with Buddhist culture in your part of the world? I'd certainly like to know how you manage to square commercial excess with the original philosophy :-p
Anyway, also good health to you and let's hope sharing bad experience is mutually beneficial as it enables others not to make the same mistakes.
