Found this little guy in the cactus garden too.
Sadly, I'm really starting to realize how much chromatic aberration my Tamron 75-300mm has at long focal lengths. Sadly, the macro option is only at the long end, so it hurts it a lot as a macro lens. With this lizard, I just couldn't get all of the CA with Paint Shop Pro XI. In fact, a few other pictures just couldn't be saved.
