At the end of last summer I had the chance to shoot hummingbirds at a butterfly bush (Buddleia) in my yard. I decided to try using the Sony FE 200-600mm f5.6-6.3 G OSS lens. I usually use my 90mm macro at close quarters but the sound of the shutter clicking does disturb the bird so I decided that distance that the 600mm would allow me to use might avoid this problem. It did and I was able to get some naturalistic shots without the nervous little buggers skittering away.
