Just a camera and sometimes a tripod with a gimbal head. But I don't often have a chance to use it. Usually only if it's quiet enough or if water is low enough. I took these pics handheld because it was easier to control the boat this way in strong wind. I'm thinking about a holder that can be easily mounted but haven't found anything suitable yet.What equipment were you using, shooting from a canoe...?
The best I can do from today.
And some more - I took the 5DIV with bare 400mm f/4 to get these shots for you, sacrificing resolution for speed.
