Every lens out there has a sweet spot, which refers to the aperture at which the lens produces the sharpest image. It is all about finding that sweet spot and applying it. The sweet spot of the Nikkor 70-300mm which was used to take this photo, is f/8. As long as there is enough light, this is the aperture at which I will shoot this lens at. This Hermit Thrush showed up before the blizzard hit and continued to enjoy seed at the feeders after the storm had departed. Every once in a while, it would perch right in front of my dining room window, allowing for great, full-frame shots.
