Micro Four Thirds Mount: The Olympus M.Zuiko Digital ED
300mm f4.0 IS PRO lens has a Micro Four Thirds mount, and is compatible with the Olympus PEN
and OM-D interchangeable lens cameras.
Lens Construction: The 300mm f4.0 IS PRO lens delivers
superior optical performance due to the multiple lens elements that make up its
construction. There are 17 lens elements in 10 groups. The lens includes 3 Super ED,
1 E-HR, and 3 HR lens elements to reduce color bleeding and chromatic
aberrations that typically occur in super-telephoto lenses. The lens also features Z Coating Nano lens coatings to
eliminate lens flares and ghosting caused by in-frame light sources.
Weather-resistant: The M.Zuiko 300mm PRO lens features
premium metal construction that is hermetically sealed in 17 locations to protect the inner
workings from moisture and dust. The lens is not only splashproof and dustproof,
but is freezeproof down to 14°F (-10°C) to complement the weatherproof camera
body of the Olympus OM-D line.
Image Stabilization (IS): The lens features internal image
stabilization that works hand-in-hand with the 5-Axis Image Stabilization found
in select OM-D cameras to give you compensation of up to 6 shutter speed steps.
With this Synchronized Image Stabilization, you get crisp, clear telephoto
images, even without a tripod. You can turn the image stabilization on or off
via the IS switch on the lens barrel.
Auto Focus: The M.Zuiko Digital lens is equipped with a
single internal focusing element that gives you blazing fast autofocus
performance. The lens has silent autofocus and aperture mechanisms to make the
lens Movie and Still Compatible (MSC). Most OM-D cameras have a Silent Mode with
an electronic shutter that let you focus and shoot in complete silence.
Focus Limit Switch: The 3-way Focus Limit Switch lets you
limit the focusing range of the lens. If you know ahead of time that your focus
range will be short or distant, you can significantly cut the focusing time by
selecting the range. You can choose from the following ranges: Full Range (1.4
meters to infinity), 1.4 (55.1") to 4m (13.1'), or 4m to infinity.
Manual Focus Clutch: The 300mm f4.0 IS PRO lens features a
manual focus clutch on the focus ring to let you instantly shift from autofocus
to manual focus. The clutch allows you to manually preset a focus position using
the distance meter. When you pull the clutch ring toward you from the AF mode,
the lens returns to the preset focus position.
Integrated Lens Hood: The lens includes an integrated lens hood which
can be pulled forward to
help prevent stray light from entering the lens. When in use, the lens hood also protects the front lens
element from scratches and damage. The lens hood adds nearly 2" to the
overall length of the lens when extended. The hood cannot be removed from the
Lens Function Button: The L-Fn (Lens Function) button on the
barrel of the lens can be programmed to perform one of 27 different functions.
Tripod Mount: Because of the length and weight of the lens,
the M.Zuiko 300mm PRO lens comes with a tripod mount. The tripod mount gives you
better balance when shooting from a tripod. You can also quickly rotate the
camera from portrait to landscape orientation, or vice versa, with the tripod
mount. Marks at 0°, 90°, 180°, and 270° let you perfectly align the camera. The
tripod mount's base is compatible with many quick release shoes found on
professional tripods. When not in use, the tripod mount can be removed and
replaced with the included decoration ring.
