I tried using my ML-L3 today with the D7000 and suspect that I am doing something wrong. I found that in both immediate and mirror delay modes, I needed to partially depress the shutter button to get the camera to focus before I used the remote. The camera would not focus before shooting when I used the remote.
I also found that in mirror-up mode the camera would sometimes fire the shutter once or twice instead of simply raising the mirror in anticipation of the next button press to activate the shutter.
I re-read all of the relevant sections in the manual, but haven't yet figured out what I'm doing wrong. Could anyone offer any suggestions?

I suspected it was user-error rather than a camera problem. I thought for some reason that the camera would focus and then release when using the remote. Thinking this through, with the manual shutter you get the auto focus with the first half of the button travel. With the remote, you only get the shutter trigger. Funny how clear these things can be after a night's sleep.
The mirror-up release mode is really nice. Press the remote button one to raise the mirror and a second time to release the shutter and drop the mirror after the shot. Having the various release modes on the new dial is a wonderful feature.
I don’t know if this is your issue, but I have noticed an anomaly when using the ML-L3 remote.
I first noticed it when using it with my D80, and it appears it occurs as well with the D7000. When in AF-S if you half-press the shutter and achieve focus lock but don’t take the shot, but then manually override the focus (or reframe or move camera position needing refocusing), then when using the ML-L3 it will not refocus. But if you half press the shutter without achieving focus lock, the Ml-L3 will again activate AF when pressed.
