First Super-Telephoto Zoom to 800 mm

The Sony FE 400-800mm f/6.3-8 G OSS is a super-telephoto zoom lens for Sony E-mount mirrorless cameras. It covers a 400 mm to 800 mm focal range with a variable maximum aperture of f/6.3-8. Internal zoom keeps the lens length and centre of gravity stable during operation. Six ED glass elements control chromatic aberration for high resolution and natural bokeh throughout the range.

Wildlife and Action Shooters Needing Extended Reach

This lens suits photographers who need a single optic for distant subjects such as wild birds, animals or field sports. The fast, precise autofocus tracks quick motion, while internal zoom aids steady handheld use. Buyers who require a wider maximum aperture for low light or shallower depth of field should consider faster primes. Those needing a shorter minimum focal length for general telephoto work will find the 400 mm starting point limiting.

800 mm Native Focal Length Extendable to 1600 mm

The defining specification is the 800 mm native maximum focal length, a first for a Sony zoom. Compatible 1.4x and 2.0x teleconverters extend reach to 1600 mm while maintaining autofocus. This focal range decides whether the lens matches the subject distances you shoot.

Questions about this item

How much power does the 400-800mm f/6.3-8 G OSS draw when the optical stabilisation runs all day?

The lens has no published power draw; its optical steady-shot system is powered directly by the camera body, so continuous use simply adds to the camera's normal battery consumption.

Which camera body and mount does the FE 400-800mm f/6.3-8 G OSS require to operate?

It requires a Sony full-frame E-mount mirrorless body such as the Alpha 1, Alpha 9 or Alpha 7 series; the lens will not function on A-mount, Micro Four Thirds or other systems.

Will the 400-800mm f/6.3-8 G OSS focus correctly on an older Sony Alpha 7 II body?

Yes, the lens is fully compatible with the Alpha 7 II; autofocus and optical stabilisation work normally, though continuous AF speed benefits from newer bodies with updated processors.
