Couple of cardinals on snow

Shooting with a different then usual lens this past weekend was a great fun. I knew that with the increasing focal length, the depth of field decreases, but it was interesting to look back at the images and see how it works in practice. I had the 50-500 mm Sigma rented, and I was photographing birds in bird bling in nearby nature area. The image below was taken at 380 mm at f/7.1. Although on most lenses f/7.1 would be already a “medium” aperture (not too shallow, closer to all-way through sharpness), at this focal length it rendered the female cardinal at the back already blurred. It provided nice depth to the image, and tells a better story of those two birds than sharp-all-the-way would.
