Pentax-F* 300mm f4.5 with 1.4x Pentax extender (420mm)
1/500 sec. f8, handheld
I had been trying to use the 420mm lens-and-extender combination on a tripod for sharper shots, but training the bulky rig on a moving target was just too difficult. Handholding in the shade became possible at a high ISO that allowed a fast shutter speed to avoid motion blur. In-camera shake reduction, a feature of Pentaxes, helped as well.
