(From Nikon lens literature) Building on the popularity and versatility of broad focal range lenses, the new AF-S 28-300mm ƒ/3.5-5.6G ED VR is Nikon's first FX-format lens with a 10.7X zoom range for enthusiasts and professionals. The new 28-300mm is the all-in-one optical solution that is ideal for travel, landscapes, portraits and capturing distant subjects. The 28-300mm VR lens is optimized for edge-to-edge sharpness on both FX and DX-format D-SLR cameras, and has an equivalent focal length of 42-450mm when attached to a DX-format DSLR. Its optical formula includes two ED glass elements that effectively minimize chromatic aberration, even at the widest aperture settings, and three Aspherical Lens Elements that virtually eliminates coma and other aberrations at wide aperture settings as well. This high performance lens also incorporates an M/A Focus Mode Switch that enables quick changes between manual and autofocus operation, and Internal Focus (IF) providing fast and quiet autofocus without changing the length of the lens while retaining working distance through the focus range.
