I caught this second-year herring gull in mid-hop between these pilings thanks to the extra reach of the Sigma 1.4 Teleconverter paired with the 120-400mm on a Canon EOS Rebel XTi. I can’t wait ‘til the next time I can book a whole day in the field to visit the shorebirds! 1/1250 at F8 ISO 400. 1.4x and 120-400mm zoomed all the way out.
