Sigma EX DG OS APO 726306 80-400mm
The constant f/4.5 aperture across the 80-400mm range, Optical Stabilization, and four SLD glass elements deliver sharp telephoto images with controlled chromatic aberration. Its Hyper Sonic Motor provides fast, quiet autofocus with full-time manual override, and the lens barrel remains a fixed length during zooming for easier handling. This lens suits Nikon F-mount shooters who need a single super-telephoto for distant wildlife and close-up detail without swapping optics.
