I just received a Sigma 600mm reflex lens that was made for Sony A cameras. While it isn't up to the Q of my Sony 70-300 APO G, it runs a pretty good second. The Sigma is a difficult Manual focus lens to get decent results with, but it is very good when you get the focus spot on. This image was made through a double panned window.
Beautiful, Ron! Excellent rendering of colors.
