I'm new here and would like to order a NN5 or 3 for my camera along with an easy leveler II. I'm not too sure which NN I need for my camera. I have a Canon 5d Mark II with a 24-105 lens.The concern is I'm also going on a trip and need the product to arrive at my house this week asap. So I' like to know if this is in stock and can get to me in time. Thanks for your concern.
