What are the essentials for camera kits for SLRs?

For a beginner, camera kit essentials include: the body of the camera, a 50mm lens, a wide-angle lens, (lower than 40mm),a zoom lens, filters, a cleaning kit, and, of course, a camera bag to keep it all it. The specifics really depend on your individual needs. I would also recommend speaking with someone at your local Photography store when you decide to purchase your equipment.
