The Starter Kit includes the 200DG Digital Gadget Bag, which is large enough to hold up to two SLR bodies and up to three lenses with accessory side pockets and a weather-flap lid - it is designed for both travel use and storage. (Measures 10.5" x 7.5" x 7"); the NB-2LH Lithium-Ion Rechargeable Battery, which is compatible with the Canon Digital Rebel XT Camera and select PowerShot, Elura, Optura and ZR cameras; and a UV-1 58mm UV Haze Filter, which is used by many photographers to protect the front element of their lens from abrasions, dust, and moisture and has a very subtle warming effect, which can be useful to counter the "cool" colors you sometimes get in bright sun or in shade.
