This idea was taken from Dirk Guttman's recent posting on the use of 35mm format lenses reverse for macro photography with digital camera's, I liked what I saw so much of the fly on the pen and the macro shot of the eye's of the fly posted by Dirk, that I decided to give it a try, and this was my result using a coin which measured 3/4 of an inche across the circumference, not bad I'll say, can't wait to get hold of some insect's to experiment with.
