There were two Anna’s Hummingbirds in the yard, one chasing, one being chased. This Anna’s is the one doing the chasing now perched, resting, and overseeing his domain. I used the Nikon D6 and Nikkor 500mm PF. It’s nice to have the 500mm PF lens back in my hands. I am renting this one for an upcoming trip because my own 500MM PF is at the Nikon Service Center in Los Angeles for routine maintenance. I’ve been without it for two and a half months and have been using the 300mm PF with the 1.4X teleconverter in its place to photograph hummingbirds. When I first attached the 500mm PF to my new Nikon D6 I thought something was wrong. I soon realized I was getting too close to the subject. The 300mm PF allows me to within 4 1/2 feet of the subject and with that lens, I am able to approach the hummers that closely. The minimum focusing distance of the 500mm PF is twice that so I have to remember to step back a bit to achieve focus.
