You're right. It's very difficult to find anything about burst mode for this camera. At least one review says it has a "continuous drive." However, if this feature is important to you, contack Nikon first to make sure the camera has a true burst mode.

http://www.nikonusa.com/template.php?goingto=cu_contact1&cmd=init&cat=1Mike, my Nikon 5400 has the Multi-shot 16 feature. It takes sixteen photos in rapid succession and combines all the thumbnail-like images all into a single image. I tried it once a long time ago and find it rather useless, but others may not.
