MALE RED-BREASTED MERGANSER, CHICAGO BOTANIC GARDEN, GLENCOE, ILLINOIS, APRIL 6, 2014
Pentax F* 300mm f4.5 with 1.5x Kenko teleconverter (450mm total)
1/500 sec. f6.3 (effective f9)
This is really a "meh" shot, but it has the virtue of being the first red-breasted merganser I've photographed this year. They're on their way north and several stopped at the Botanic Garden today to rest and refuel. The combined 450mm of lens was not easy to hand-hold, but it did the job.
