I just read your interview and see I have much to learn. How did you get so close to that snarling bear?!
In my defence I don't use even a camera but a simple iPhone 7. Where I generally go is dangerous with floors that can collapse at any time, and I need both hands.
I have found that a stable shot and consideration of what's in the background etc... helps a lot.
I used a long telephoto lens for the bear.
Agree you don't want too much weight urban exploring. Perhaps you need a drone that follows you around on tracking mode ;-)
