The tiny Costa’s Hummingbird was quite cooperative a few weeks ago in Arizona. He was in a shrubby area with lots of obstructions so I took my camera off the tripod and walked a few feet to get a better view. The Nikkor Z600PF is lightweight and hand-holding it lets me move easily to follow a bird without the burden of a tripod. I was able to track him and when he perched, the freedom of hand-holding let me move easily to avoid obstructions.
