When you purchase a new digital camera, there are usually a few items you need to round out the camera's included accessory package. With that in mind, B&H Photo has put together this Basic Accessory Kit to make your picture taking experience more enjoyable.
In addition to the standard accessory package that is included by the manufacturer with the Nikon D3100 Digital SLR Camera with an 18-55mm VR Lens, the Basic Accessory Kit includes a 16GB memory card, a camera bag for transport and storage, a 52mm protection filter, a spare battery, a wired remote shutter release, a cap keeper, and an LCD screen protector.
