Sparrow (Sigma 150-600mm with x1.4 Teleconverter)

[jeffashman]

A couple of pix of a sparrow at the feeder, testing my Sigma 150-600mm with the Sigma x1.4 Teleconverter. The images are a little soft, but not bad. The lens combo is slow to focus, so it would be a challenge to catch birds in flight. Autofocus works well in light; haven't tried in darker areas.
