Sigma 70-300mm f/4-5.6 DG Macro APO

Very nice.... but too hard understanding DOF in 200mm or 300mm need close diaphragm near 22 or more for good DOF but in wind and poor light the shot is very hardly.

macro work only in 200-300mm diapason and swithing is not a problem only then you turn of macro mode. because each time need switch in manual focus and set in more then 1.5 metre.
and once more then lens an the camera and camera have a direction to bottom the lens can change focal distance by self I mean this is not fixed.
