I like the photo, but seems to be a bit out of focus.
I was trying to get a simialr shot the other day. I saw a chipmunk run into a small hole on a tree the other day, so I sat there for nearly 30 minutes waiting for him to poke his head back out of the hole, so I could get a good shot, but needless to say, he never came out.
LOL, I knew it.
300mm on D-70 equals with 390mm on 35mm camera, right?
Well, using it handheld is not a problem, but in such case you have to obey the focal lenght rule - the longer the focal lenght, the faster shutter speed is to be used! 1/500s would be optimal in this case...
