AMERICAN ROBIN, CHICAGO BOTANIC GARDEN, GLENCOE, ILLINOIS, APRIL 15, 2015
Pentax F* 300mm f4.5 with Pentax-HD 1.4x converter (420mm)
1/1000 sec. f8
An hour on the hunt in the Botanic Garden this morning, and all I got was this robin. At least I learned that handholding a 420mm lens-and-converter combination is possible, and that the image quality is more than acceptable.
