Some people are not interested in the lens that comes with the kit, and would prefer to buy the body of the camera and then separately buy a different lens. That is what I did and it was an affordable way to get a higher quality camera and lens.
The Rebel T3 doesn't ships factory with the lens. This seller removes the lens and sells just the body. (I assume they sell the lens seperately for an extra profit?) It's a decent deal if you have an extra lens around.
This item was originally a camera "kit," which included the camera body, a lens, battery charger, etc. But the seller has removed the lens to sell separately, leaving everything else. There is NO LENS with this camera... even though it shows one on the box. It is camera body only, and will only work if you have your own lens. Worked well for me because I already had a lens and didn't want to be paying more for another one.
This item is the body only. It does not include your basic kit lens. I bought the body only because I already had my kit 18-55m lens from my older Canon Rebel camera so there was not point in me purchasing another lense.
The camera is packaged as a kit with a lens. If you buy just a body they remove the lens and sell the camera only with its peripherals. They then add a sticker to the kit box that the lens has been removed.
