Today I took an AI-converted 135mm f2.8 out with the D40 for a while this afternoon. I wasn't as happy with this combo as I was with the 85... The effective focal length would be about 200mm, maybe I'm just not used to it. Anyway here are a few shots.

A couple of seagulls circled, hoping for a snack (this one is cropped somewhat):
This shot shows how narrow the depth of field is at f2.8. The shell was maybe 3 inches across, sitting right on the rock (out of focus in the background):
Moonrise. Time to go home:
