Announced alongside Nikon's first full-frame camera--the 12MP D3--in 2007, the AF-S Nikkor 24-70mm F2.8G ED is a fast, high-quality standard zoom for FX (full-frame) and DX (APS-C) Nikon DSLRs. The 24-70mm F2.8 covers an effective focal length range of 36-105mm on Nikon's APS-C DSLRs, but this weather-sealed lens is most at home on full-frame cameras like the D800 and professional D4. Optical construction comprises 15 elements in 11 groups, and includes 3 ED (extra low-dispersion) elements, three aspherical elements, and Nano Crystal Coating. This lens gives excellent central sharpness 'wide open' at F2.8, improving rapidly upon stopping down, and is only really weak at very close focus distances.
