500mm F4 G SSM SAL500F4G
Perfect for photographing athletes and wild animals, this lens provides
ideal performance thanks to impressive specifications such as a bright f/4
aperture and the ultra-telephoto 500mm focal length. Lens construction
includes 11 elements in 10 groups specially developed to deliver beautiful
background and foreground defocusing. Its smooth circular aperture,
formed by 9 aperture blades, contributes to rounder, more beautiful bokeh.
A Nano AR Coating and velvet lining also minimize flare, eliminate opacity
and tighten blacks. Furthermore, three ED (Extra-low Dispersion) glass
elements compensate for color aberration to realize sharper image quality.
