Sony FE 100-400mm F/4.5 GM + 1.4x Teleconverter
Meet Sony's professional 100-400mm zoom without compromise. With a constant f/4.5 aperture, four XD Linear Motors for 3x faster autofocus with 50% better focus tracking, and an internal zoom design weighing just 1,840g, this is the ideal lens for wildlife, sport and photojournalism. Never miss a decisive moment again, from unpredictable birds to lightning-fast athletes.
Always the right exposure, at every focal length
The FE 100-400mm f/4.5 GM OSS is the only lens in its class with a constant f/4.5 aperture across the entire zoom range. That means no exposure shift while zooming, consistent shutter speeds when tracking fast-moving subjects, and smooth bokeh throughout the zoom range from 100mm to 400mm. For sports photographers working in changing light conditions, or nature photographers who need to react instantly to an unexpected movement, the constant aperture is a crucial advantage over lenses with a variable zoom.
Never miss a decisive moment again
Four XD Linear Motors and advanced control algorithms deliver an autofocus speed up to three times higher than previous models, with around 50% better tracking performance. The floating focus groups are driven with extreme precision, keeping the subject sharp even during unpredictable movement. Combined with the Sony Alpha 9 III, the lens supports AF tracking at up to 120fps, making it ideally suited for capturing flying birds, sprinting athletes or other fast action moments where there's no room for maybe.
Shoot all day, without fatigue
The internal zoom design means the lens stays the same length at 100mm as it does at 400mm, keeping the centre of gravity constant so the lens always stays perfectly balanced on a tripod or in the hand. Weighing around 1,840g, the lens is relatively light. For photographers who work long days on location, whether on a tripod or handheld, this means less fatigue and more freedom of movement. The internal design also prevents dust from being drawn in while zooming, which is essential when shooting outdoors in difficult conditions.
From 100mm to 800mm, without swapping lenses
The lens is fully compatible with the Sony SEL14TC (1.4x) and SEL20TC (2.0x) teleconverters, extending the effective range to 140-560mm and 200-800mm respectively. Crucially, full G Master image quality is retained when using teleconverters, which isn't the case with many other lenses. This effectively makes the FE 100-400mm F4.5 GM OSS a versatile system that handles a wide range of shooting situations with a single lens body, without ever having to swap lenses or miss a valuable moment.
Built for the toughest conditions
For professionals working in demanding environments, the lens offers a built-in security lock, suitable for use with a security cable in press areas, stadiums and fixed setups. All buttons and rings are sealed for a rugged, dust- and moisture-resistant construction, so the lens keeps performing reliably even in harsh weather. The front element also features a fluorine coating that repels contamination and is easy to clean, safeguarding durability and image quality in the long run.
Swap filters in seconds, without removing the lens
The lens features a drop-in filter slot at the rear, letting you quickly and easily swap ND filters, polarising filters or other filter types without taking the lens off the camera. For sports and nature photographers who need to switch quickly between strongly changing lighting conditions, this is a significant practical advantage. A large front filter is impractical and expensive on a lens of this size; the drop-in solution offers a professional, affordable alternative that fits into a fast on-location workflow.
Sony E-Mount 1.4x Teleconverter
With the high-quality Sony E-Mount 1.4x teleconverter, you can extend your lens's focal length by forty percent without any loss of image quality. Communication between the lens and the camera body, such as passing data for metering, autofocus and optical image stabilisation, is fully supported. The Sony full-frame teleconverter with E-mount also features a dust- and moisture-resistant construction, so it can withstand the toughest conditions.
An extender is a compact and lightweight way to bring your subject in closer and larger. With the Sony E-Mount 1.4x teleconverter, for example, you can shoot with the Sony FE 70-200mm F/2.8 GM OSS lens as if it were a lens with a range of 98-280mm. The maximum aperture is reduced by around one f-stop. That means with a lens with a maximum aperture of F/2.8, you can shoot at F/4.0 as the maximum aperture.
