I'm new here and I'd like to order the NN5, I think. Not to sure what I need for my camera. I have a Canon 5d Mark II with a 24-105 mm lens.. I'm leaving on a trip this week and would like the NN to arrive at my house asap. With out being able to speak to anyone I hope my query can be answered in time. I'm hoping what I need is in stock . These look like fine products and I'd like to order immediately. Thanks for your concern.
