Bald Eagle STARE

Immature American Bald Eagle STARE (Hailiaeetus leucocephalus, Pygarge a tete blanche, BAEA) Kachemak Bay (near Homer), Alaska ©Christopher Dodds All Rights Reserved. Canon EOS 1DX, 100-400mm f/4.5-5.6 L IS II USM @400mm and Canon EF 25mm Extension tube II. ISO 400, f/13 @ 1/400s Manual. PURCHASE A PRINT or LICENSE IMAGE FOR PUBLICATION HERE.

I always carry extension tubes so I can physically connect both my Canon Extender EF 1.4X and 2X (Version III) when I want a really close image, they also reduce the minimum focusing distance when I get really close. During my Bald Eagles Galore Photo Tour in March, I used the new Canon 100-400mm II lens for most of the trip. When this immature Bald Eagle landed right beside me, I instinctively crouched-down, and attempted a really close portrait, but realized that the bird had landed slightly within the minimum focusing distance of the lens; it was closer than 38.4" or 980mm (do note this is the distance from the sensor, not the front element of the lens). I quickly added my Canon  EF 25mm Extension Tube to be able to focus without moving away from the inquisitive Eagle.
