Specification :
The FE 400-800mm F6.3-8 G OSS is the first α Lens to cover a 400 mm to 800 mm super-telephoto range. An optional 2x teleconverter can extend maximum focal length to 1600 mm. The internal zoom means the length of the lens does not change, and the centre of gravity stays within a small range for stable handling. Smooth, easy zoom ring rotation allows precise zooming, while careful design prevents accidental focal length changes.
Six ED (Extra-low Dispersion) glass elements effectively control chromatic aberration. Flare and ghosting in backlit conditions are also thoroughly suppressed. An 11-blade circular aperture helps to create beautiful ball bokeh amid exceptionally smooth, creamy background bokeh when shooting with a narrow depth of field.
Two precision linear motors drive the lens’s focus group for fast, accurate focusing. Tracking easily keeps up with the 120 fps maximum burst speed of the α9 III, and continues uninterrupted even while zooming so important moments are not lost. A focus-range limiter (FULL / 10m-NEAR / ∞-8m) can be used to optimise operation for different subject distances. Focus breathing is suppressed for refined movie quality and quiet operation expands the gamut of possible applications.
The optically stabilised FE 400-800mm F6.3-8 G OSS extends to 800 mm, but weighs just 2475 g (87.4 oz) and can be used handheld without shake-induced blur. Stabilisation is even better with an α body that includes image stabilisation. When using a tripod, the mount foot can be quickly rotated for horizontal or vertical orientation. Durable components, optimised balance, and a non-removable foot maximise reliability and performance.
Three focus hold buttons at 90° increments around the barrel allow easy access in any orientation. Other functions can be assigned to the buttons as needed. Internal zoom and a dust/moisture resistant design maximise reliability. The front element has a fluorine coating that repels contaminants and makes the lens easier to clean. The lens hood is a new design with a lock button and filter opening for easy operation.
Impeccable Sony G Lens design emphasises a graceful balance between high resolution and gorgeous background bokeh that can enhance the artist’s vision.
