Sigma 150mm f2.8 EX Macro was set to max. magnification (1:1). A plant is a Mediteranean weed growing from cracks in stone. Flowers are very miniature, less than 10 mm in diameter. Little green bug was barely visible with the naked eye. Nikon D200 built-in flash was used to trigger two remote Nikon SB800 flash units mounted to camera via Manfrotto 330B Macro bracket support.
