I'm going to be shooting in bright daylight from a distance usually exceeding 15 m and the subject will be yellow-white, moving, and about 1 m long by 0,5 m tall. The background will include green grass and/or browned grass. No tripod, no help with lighting, just on-the-fly sports-style shots.
Can anyone comment on the above lens? Has anyone used it to shoot outdoors at full reach in high sunlight?
