The compact, lightweight, easy super-telephoto prime
This high-performance 400 mm F4.5 super-telephoto prime lens is the world’s lightest1 at just 994 g (35.1 oz., minus tripod foot). An extraordinary combination of G Master optics and the latest mechanical design achieves remarkably low weight, smooth handling, and minimum fatigue while delivering outstanding image quality when shooting handheld. Overall length is just 242 mm (9-1/2 in.) for outstanding mobility.
Superb G Master sharpness for breathtaking detail
Super ED (Extra-low Dispersion) and ED glass elements in an advanced optical design minimize aberration for high resolution that befits the G Master brand. Sony’s original Nano AR Coating II effectively suppresses flare and ghosting for superior clarity and contrast in backlit conditions. An 11-blade circular aperture and individually optimized spherical aberration contribute to smooth, creamy G Master bokeh.
