Playing with macro photography is fun and, when I came across a small frog in our back garden, I grabbed the macro lens.  Clearly, the frog was not totally impressed by my interest in its presence, but I tried to get close to it without spooking it.  It did allow me to get a little closer but getting a good focus on its head when things are dynamic was a little tricky.  I got a lot of shots with the body in focus but not the eyes.  Still, a few worked out okay.
