Just to show how good the E-PL1 and the Panasonic 14-140 lens can be, I only had a couple of seconds to take this image of a Hummingbird Moth. For those of you have seen them, you know how quick they can be. They only stop for a couple of seconds at each bloom. Some say that focusing on the E-PL1 is slow, but after I took this picture I'm wondering what slow is. It's plenty fast for me.

Don't forget, this lens is pretty heavy compared to other m4/3 lenses and is made for video. There's a lot of glass in there to move when focusing.
