General Brand 77mm White Balance Lens Cap Disk for Digital SLR CamerasThe White Balance Lens Cap is great for use with digital cameras. Just place the cap over your lens, point your camera at a subject area, and the incoming light is diffused to create an average white balance for a particular scene (check camera manufacturer's manual for setting white balance). The White Balance Lens Cap easily slips on to the front of any appropriately sized lens, or a lens with a protective filter. Even if your lens has a bayonet mount on the outside, simply use the bayonet adapter provided. The lens cap comes with a handy loop to connect it to a camera strap or strap lug so you don't lose the cap.
Sigma 120-400mm f/4.5-5.6 AF APO DG OS HSM Telephoto Zoom Lens for Nikon Digital SLR Cameras The Sigma 120-400mm telephoto zoom lens covers a telephoto range of up to 400mm, letting you bring almost any subject close for short-perspective shots. The lens employs Sigma's original Optical Stabilizer (OS) function, which gives you access to shutter speeds approximately four stops slower without blurring the image. As a result, you can capture low-light, long-distance shots such as football plays, wildlife profiles, and landscape scenes without using a tripod for each photo. In addition, the lens incorporates a Hyper Sonic Motor (HSM) for quick, high-speed autofocusing, along with a rear focus system that guarantees optimum image quality throughout the entire zoom range. And photographers will love the three special low dispersion (SLD) glass elements, which correct for chromatic aberration, and the super multilayer lens coating, which reduces flare and ghosting. Other details include a minimum focusing distance of 59.1 inches, a maximum magnification ratio of 1:4.2, and support for optical 1.4x EX DG APO and 2x EX DG APO tele converters.
