One of my best, if not my best lens. Excellent for wildlife/nature photography. Whilst keeping the necessary distance from animals and birds, it allows for excellent detail, focusing, easy control of depth of field, excellent light capture and colour rendition.
I took this photo at the Nairobi National Park, Kenya: a "hartebeest" (Alcelaphus buselaphus), also known locally as Kongoni, against Nairobi's skyline in the background.
