The constant f/4 aperture combined with two FLD and one SLD element delivers exceptional clarity and chromatic aberration correction, while the magnesium alloy body provides a dust- and splash-proof build at 3310g. Its optical stabilization offers a 4-stop advantage, and the Hyper Sonic Motor provides fast, accurate autofocus that excels in challenging low-light conditions. This lens is best for wildlife and sports photographers who need a durable, hand-holdable 500mm prime with full-frame coverage and reliable weather sealing for extended outdoor shoots.
