Canon EF 600mm IS L USM
A 600mm prime is the go to lens for wildlife and sports. This Canon 600 is from the first generation, so it is on the heavy side, but the optics are world class sharp. Razor blade sharp. A new one is lighter, but costs 3X more.
I am the second owner having acquired it from a friend who is a National Geographic contributing shooter. It is in pristine condition and never saw severe field conditions. I am entering my 7th decade and am slowly converting over to Sony. I want something lighter with a native Sony mount, though this lens provides uncompromised results on any mirrorless camera with the appropriate adapter, Sigma, Metabones, etc..
Note that mounting this lens on a C size sensor body, (Canon 7D, etc.), will give an effective focal length of just under 900mm!
$4200 or reasonable offer. Located in upstate New York. Personal inspection is encouraged.
Note... I am new to the forum but an active shooter for many years. Some of my work can be seen on IG @pjyarnall. PM me with any questions.
