I am getting more appreciative of just how hard Macro work is now that I have started to experiment myself with the Sigma 180mm f/3.5. This is simply brilliant. I love the silvery detail on the hairs, the focus on the antennae and your border. Cropping a bit tight and bokeh a bit OE (-1). I'm bumping to a 9. Please tell me how or what ring flash you used and the exposure thereof! Roz?
