White Mandevilla

To photograph this white Mandevilla I have tried a different combination of lenses.
I have photographed with the Canon 70-200 f 2.8 MK II. Here I placed 3 intermediate rings to get closer. Normally the minimum distance of the 70-200 is 1.20 meters. With the intermediate rings 12, 20 and 36 mm (total 68 mm) I could come to less than 80 cm. This also created a beautiful bokeh.
