Overview: The Sony FE 100-400mm f/4.5-5.6 GM OSS G Master lens is a full frame (35mm)
super-telephoto zoom lens that is ideal for sports and wildlife photography,
and other subjects that require a long reach. G Master lenses feature the
most advanced optical technology to achieve spectacular resolution. The
SEL100400GM has a 9-blade circular aperture for gorgeous background bokeh
(blurred background elements). The lens comes with front and rear lens caps,
tripod collar, lens
hood, and a soft zippered storage case.
Compatibility: The SEL100400GM has a Sony E-mount, and is compatible with
α-series Interchangeable Lens Cameras with the E-mount, and works best with
cameras with full frame (35mm) image sensors. It also works with E-series camera
with an APS-C image sensor, however, the equivalent focal length will be
150-600mm, and the image will be cropped.
Lens Elements: The SEL100400GM has 22 lens elements in 16
groups, including two ED (Extra-low Dispersion) glass elements and one Super ED
glass element to reduce axial chromatic aberration. Sony's Nano AR Coating
suppresses reflections that cause flare and ghosting in backlit and other
challenging lighting situations. The front element has a fluorine coating that
helps prevent dirt and fingerprints from sticking. You can easily wipe smudges
away in case they appear on the lens surface.
Focusing System: The lens features a double linear motor and
DDSSM (Direct Drive Super Sonic wave Motor) for fast, accurate autofocusing. The
DDSSM operates silently, making it ideal for shooting movies in scenes where the
focus is constantly changing.
Controls: The FE 100-400mm lens has large zoom and manual
focusing rings. A zoom smoothness adjuster lets you increase or decrease the
tension for rotating the zoom ring. The adjuster has a range of "smooth" to
"tight." Other lens controls include:
- Focus Mode: You can switch between Autofocus (AF) and Manual
Focus (MF) with this 2-way switch. For AF photography, both the camera and the
lens must be set to AF. For MF photography, either or both the lens and camera
should be set to MF.
- Focus-range Limiter: If the subject distance will be fairly
consistent, you can limit the range of the minimum and maximum focusing
distances. This helps save time when making small focus adjustments. The 2-way
switch lets you choose between Full (no limit) and Infinity (∞)
- 3m (when the subject is 9.8 feet away or more).
- Optical SteadyShot: The lens has built-in Optical
SteadyShot, making it easier to shoot blur-free images without a tripod. When
used with α-series cameras featuring in-body
stabilization, OSS will provide 5-axis stabilization.
- OSS Mode: When Optical SteadyShot is engaged, you can
switch between Mode 1 (compensate for normal camera shake) and Mode 2
(compensate for camera shake when panning moving subjects).
- Focus Hold: Three focus hold buttons are placed around
the lens barrel. When shooting in AF, you can press a focus hold button to
turn off autofocusing to fix the focus before shooting. To start AF again,
release the focus-hold button and press the shutter button halfway.
Optional Teleconverters: The SEL100400GM is compatible with
Sony's high performance teleconverters. The
SEL14TC provides a 1.4x increase in focal length, while the
SEL20TC increases the focal length by 2x. That's a maximum focal length of
800mm (35mm) or 1200mm (APS-C).
Tripod Mount: The lens comes with a removable tripod mount
that allows you to quickly attach or remove the camera from a tripod. Because of
the size and weight of the lens, attaching a tripod to the lens' tripod mount
provides better balance and security. When using the tripod mount, you can
easily switch between horizontal and vertical shooting by loosening the
ring-locking knob and rotating the lens inside of the collar. Tripod collar ring
indexes (gray dots) are located at 90° intervals on the collar ring for precise
Lens Hood: The SEL100400GM comes with the ALC-SH151
pro-style lens hood
for blocking incidental light that may cause flare and ghosting to maintain
optimum clarity and contrast. The hood has an access window for operating a
polarizing filter without having to remove the hood. A hood lock switch is
provided to prevent accidental detachment or rotation of the lens hood while
shooting or moving around.
