I use a Nikon D700 and just acquired a used MB-D10 battery carrier. I really have two questions: 1) I want to take advantage of the 8 fps rate I can get from the MB-D10 and understand I will need to use either a different battery and charger (EL-4) or AA batteries. Which AA batteries work best to get the 8 fps, ie. some are better than others? Is there a camera body setting which should be changed for this type of battery use?
My second question is: 2) I would like to try birds-in-flight photography with my AFS 300mm f4 Nikkor and would like to know what settings should I use for the auto-focus? Is it recommended to use a fixed shutter speed for this type of photography?
