Red Kangaroo, Flinders Ranges National Park, South AustraliaThis one goes back quite a ways to when my main big lens was a manual focus 600mm f/5.6. I picked it up used at a bargain price and it enabled me to capture images that previously wouldn’t have been possible. I always loved the narrow depth of field and smooth bokeh. A perfect combo for late afternoon in Flinders Ranges National Park in South Australia. Without auto focus, action shots back then were always a challenge, but the quality of the glass produced lots of great portraits like this red kangaroo. Nikon D200 with Nikkor 600mm f/5.6 manual focus lens, ISO 200, f/5.6 at 1/40th of a second.
