text: Purple Coneflower (Echinacea purpurea) – 600mm(equiv.) ƒ5.6@1/160 ISO100 EV0 A long lens, in this case 600mm (equiv.) provides manageable depth of field – even at ƒ5.6 .The bokeh is excellent with only slightly contrasty edges which can be remedied in post-capture processing, if needed. This photograph was made hand-held providing a good indication of the effectiveness of Sony’s image stabilization.
