The OM M.Zuiko 150-400mm f4.5 TC1.25x Pro ED IS Lens provides a powerful, versatile zoom range of up to 640mm (35mm equivalent). It features two ED and three HR lens elements for outstanding corner-to-corner sharpness and a 1.25x Teleconverter for even greater zoom. It also offers a 5-Axis Image Stabilization for up to 7 shutter speed steps of compensation, and an advanced dust and splash resistance.

High-resolution zoom lens that enables 1000mm* equivalent super
telephoto shooting

 
The lens body features a built-in 1.25x teleconverter, maintaining high
optical performance while enabling up to 1000mm equivalent* handheld
super telephoto shooting. The optional M.Zuiko Digital 1.4x Teleconverter
MC-14 and the M.Zuiko Digital 2x Teleconverter MC-20 are also supported.
When combined with the MC-20, this lens allows focal lengths up to an
astonishing 2000mm*. The M.Zuiko Digital ED 150-400mm F4.5 TC1.25x IS
PRO features a closest focusing distance of 1.3m across the entire zoom range and close-up shooting performance with a maximum image
magnification of 0.57x*, which increases to 0.71x* when using the built-in
teleconverter for enjoying true telemacro shooting. A lavish 28 elements in
18 groups lens construction was adopted, including a newly developed

large-diameter Extra-low Dispersion Aspherical lens and four Super Extra-
low Dispersion lenses. This guarantees reduced flare and color bleeding

across the entire zoom range and superb resolution to the edges of the
image, even on a large-diameter lens with a fixed F4.5 aperture. Olympus
original Z Coating Nano technology is employed to provide sharp, clear
images also in difficult shooting environments, such as backlit scenes.

Compact, lightweight design with superb weather-resistant
performance

Magnesium alloy is used for the lens barrel and a lightweight carbon fiber
lens hood is used to ensure that the center of gravity of the lens does not
shift toward the end when the lens hood is used. The use of optimal
materials in each area of the lens helps maintain strength and precision
while achieving a compact, lightweight design with a length of 314.3 mm and
a weight of 1,875 g****. The M.Zuiko Digital ED 150-400mm F4.5 TC1.25x
IS PRO is designed to give photographers the ability to smoothly tune
settings and functions as they shoot.
Pairing it with the Olympus OM-D E-M1X and its superb dustproof,
splashproof, and freezeproof properties makes it possible to continue
shooting in harsh weather conditions such as rain and snow with complete
peace of mind. Compared with the black coating on conventional lenses, the
heat-resistant coating on this model efficiently reflects the infrared rays of
sunlight, keeping temperatures inside the lens from rising even in blazing hot
weather for stable optical performance. The front element of the lens
features a fluorine coating which provides a smooth and scratch resistant
surface and makes it easier to clean for better maintenance.

 
World’s strongest 5-axis sync IS up to 8 EV steps** of compensation
and fast, high-precision AF

The M.Zuiko Digital ED 150-400mm F4.5 TC1.25x IS PRO supports 5-axis
sync IS. At 300mm equivalent*, it achieves the world's strongest image
stabilization of 8 EV steps**. Even when extending the telephoto range up to
2000mm equivalent* by using the optional MC-20 teleconverter, image
stabilization is still available. Its high image quality hand-held shooting
capabilities make the lens a perfect addition specifically for wildlife, nature
and outdoor sports photographers. Olympus’ original high-precision lens
thinning technology enables the production of lightweight focusing lenses,
enabling fast, high-precision focusing across the entire zoom range.
