I took this shot yesterday on a gloomy overcast day. I've been experimenting with my new-to-me DA* 60-250mm. I call this pushing the limits because I usually don't shoot my K-5IIs above ISO 1600, the f4.5 aperture is close to wide open for this lens, and this crop represents just under 5% of the original 16MP image. It's not a great shot, but I was happy to get any shot of a small bird that was about 75-80 feet away while hand-holding the camera.
