EH-5b does work. I think all three versions have the same voltage output. So they should all work with the D700. However, mine is defective. It has been confirmed by Nikon support. So I am in process to get my money back.
Dear God, So far today, I've done all right. I haven't gossiped. I haven't lost my temper. I haven't been greedy, grumpy, nasty, selfish or overindulgent. I'm very thankful for that. But in a few minutes, God, I'm going to get out of bed ... and from then on, I'm probably going to need a lot more help. Amen
