Key Features
Superb resolution from 100 mm to 400 mm
100-400 mm is an ideal zoom range for wildlife, birds, sports, photojournalism, and much more. An optional teleconverter can extend focal length to 800 mm for even greater reach. An ED XA (Extra-low Dispersion extreme aspherical) element plus XA, Super ED, and ED elements minimise chromatic and spherical aberration for high resolution throughout the zoom range.
Minimal ghosting and stunning close-ups
Sony's original Nano AR Coating II suppresses flare and ghosting for outstanding clarity and contrast even in difficult light. Floating focus ensures that full resolution is maintained throughout the image area even when shooting close-ups at 0.25x magnification and minimum focus distance.
Constant F4.5 maximum aperture
Maximum aperture is a constant F4.5 throughout the zoom range. There is no need to readjust shutter speed or sensitivity to maintain optimum exposure when zooming, so you can concentrate fully on composition and shooting.
Exquisite G Master bokeh
An 11-blade circular aperture unit and two XA elements including one ED XA (Extra-low Dispersion extreme aspherical) element contribute to exquisite G Master bokeh. The XA elements effectively suppress distracting onion-ring bokeh. Bokeh quality is further enhanced by careful adjustment of each individual lens, while ED and Super ED (Extra-low Dispersion) glass elements minimise colour bleeding.
Fast, precise AF and tracking
Advanced algorithms and four of Sony's XD Linear Motors drive the floating focus groups for up to 3x faster AF. Tracking performance has been improved by up to 50%. With the a9 III body, reliable AF tracking is achieved at bursts of up to 120 fps.
A great choice for movies
State-of-the-art lens technology ensures that focus breathing and zoom related focus and axial shifts are effectively suppressed for smooth, professional looking streams and movies. The XD Linear Motor drive system is exceptionally quiet too, so movie audio won't be spoiled by lens noise or vibration.
Lightweight for stress-free shooting
Magnesium alloy parts and painstaking design result in a remarkably low overall weight of just 1,840 g for a 100-400 mm super-telephoto zoom. Inner zoom minimises centre-of-gravity shift when zooming, further enhancing handling and reducing stress on the user. Even the zoom torque has been optimised to ensure smooth operation.
High-performance optical stabilisation
Advanced optical stabilisation works in concert with a in-body stabilisation to achieve outstanding results. Switchable MODE 2 and MODE 3 modes provide optimum stabilisation for panned shots and moving subjects. The system also supports a body Active Mode stabilisation, providing superior stabilisation for movies as well as stills.
Customisable for any shooting style
Four focus hold buttons allow easy access. A function ring can be assigned to control Preset Focus for quick registration and recall of a specific focus point, APS-C/Full Frame switching that allows quick shifts to the equivalent of 1.5x zoom, or Power Focus. A zoom smoothness switch and security slot are also provided.
Reliable in challenging conditions
In addition to a dust and moisture resistant overall design, the outer surface of the front element features a fluorine coating that prevents adhesion of fingerprints, dust, water, oil, and other contaminants. The coating also makes it easy to wipe the lens surface clean.
Recycled materials in our lenses
As part of our Road to Zero initiative, over 22% of this product's total plastic weight consists of recycled plastic. At the component level, the proportion of recycled material reflects its performance needs: over 11% of the plastic in the lens barrel consists of recycled plastic, over 41% in the lens hood, and over 78% in the lens caps.
Recyclable non-plastic packaging materials
As part of our Road to Zero initiative, we are transitioning to non-plastic packaging materials. Plant-based non-woven fabrics are used for product bags.
