I have developed an interest in the various insects and spiders in the area.
We have some very large spiders and a host of colorgul insects to see. A macro lens or some extension rings offer a way to capture the details
Wildlife macros are special because the subjext moves and the closer you get to more likely you are disturb the subject and "miss a good shot"
I sugest the 100mm macro or longer for this type of work. I've used the Canon 180mm f3.5 which is nothing short of spectacular!! The Nikon 200mm is another excellent choice!
