Looking for Answers about Nikon Inc. MC-36 Multi-Function Remote Cord?

Some math to help answer your question:
30 seconds = two times per minute
2 shots/minute * 60 minutes/hour * 7 hours = 840 shots

The MC-36 can count up to 399 shots. If you need the MC-36 to begin and end shooting for 7 hours in an unattended scenario, this will not work (840 > 399). However, if you can return at or after the 7 hours have elapsed, you can simply configure the MC-36 to shoot every 30 seconds until the timer is stopped manually. This is done by setting "N" to "--" instead of a number.

The MC-36 uses a 10-pin cable which the D7000 does not have. My only suggestion for this is to use the Nikon Camera Control Pro which you can set Time Lapse for as many pictures as you want or until you tell it to stop. You will need to carry a laptop with you is the only downside but works like a charm. I was able to capture the sunset every 3 seconds for 1 hour to create a nice smooth time lapse sunset.

I know it's not listed as compatible, but it does use the same pin mount.... So in theory, it should work. But, at a $114 price point, it would be nice to know for sure.... Hence the question posed to Nikon Tech.
