From time to time I have been asked what equipment and techniques I use to take macro close up photographs. I currently use a Nikon D300 and D700 body along with a Sigma 150mm macro lens with a Sigma ring flash fitted to the end of the lens. (See sigma user website for more info.) I bought the Sigma lens as Nikon didn't make a lens with this focal length and I generally need to be slightly further away from more skittish insects.
