A lot of photographers would like to have a lighter and smaller 500mm and that is easier to handhold and walk around with and possible without a big tripod. Canon had a 500mm 5.6 before.
-Highest AF speed
-If possible a built-in hood
-Soft bag, should fit lens and attached camera
-Should work well with Extender
-Detachable tripod mount
