these were shot at the desert museum in tuscon arizona. with my 40-150mm lens it was still a challenge. not only is it pretty dark in this little sanctuary but these critters move so ridiculously fast that my lens just can't keep up with them. the image that is cropped square is the one that became somewhat sharp. keep in mind i did'nt take too many shots-only about a dozon or so and without a tripod and a super dooper telephoto lens. they are descent though.
