OM SYSTEM M. Zuiko 150-400mm f/4.5 TC 1.25 IS PRO Lens

Description

OM SYSTEM 150-400mm Compact Telephoto Zoom

The OM SYSTEM M. Zuiko 150-400mm f/4.5 TC 1.25 IS PRO Lens Micro Four Thirds mount system enforces flat telecentric perspective compression over an extreme 300-800mm full-frame equivalent super-telephoto spectrum. Operating at its constant f/4.5 maximum opening resolves fine organic plumage texturing on high-density digital sensors while ensuring a signature vignette roll-off. This elite PRO-Series long-range glass architecture ensures wildlife, sports, and aviation trackers can utilize a compact mirrorless telephoto zoom alternative to pull in distant targets with absolute edge-to-edge flatness.

Light behavior is strictly managed by 28 elements in 18 groups alongside an integrated switchable 1.25x teleconverter system. This specific element configuration acts directly to eliminate axial color fringing, sagittal coma flare, and diffraction limits at the minimum f/22 to 29 aperture boundary. High-speed electronic autofocus tracks drive this heavy telephoto glass path cleanly to maintain extreme detail rendering at the minimum focus distance of 1.3 meters.

Professional Micro Four Thirds System Architecture

Native MFT data communication channels transfer high-speed electronic metrics directly to coordinate up to 8 stops of dual-power optical image stabilization. Leveraging this rapid internal interface enables outdoor reportage teams to utilize a compact mirrorless telephoto zoom alternative with unparalleled handheld sync stabilization. The electronic network ensures instant focus updates during highly demanding automated handheld tracking setups.

28-Element Precision Glass Path

The intricate internal configuration embeds one extra-low dispersion asymmetric element and up to four high-refractive index components to handle complex light paths. This structural engineering achieves complete chromatic aberration suppression at maximum focal reaches where secondary spectrum errors naturally expand. Incoming light wavelengths strike the digital sensor plane at near-perpendicular angles to lock in absolute corner clarity.

f/4.5-5.6 Light-Gathering Iris Mechanism

The constant physical aperture opening balances ambient light transmission with a highly optimized internal weight configuration. This high-efficiency layout coordinates with the internal optical formula to isolate distant targets with a smooth feathered background bokeh profile via nine rounded blades. Visual transitions roll off gracefully from the sharp focal plane into beautifully blurred backdrop layers.

Precision Autofocus Mechanics Calibration

An innovative internal stepping autofocus motor moves the internal lens groups rapidly with near-silent mechanics and high positional accuracy. This mechanical architecture delivers silent high speed autofocus tracking required for quiet theater stages or candid wildlife environments. Focus locks instantly even when tracking unpredictable sport participants across the frame boundaries.

1.88kg Ruggedized Ultra-Compact External Shell

The premium metal lens body incorporates a robust carbon-fiber reinforced hermetically sealed housing that delivers complete protection against freezing climates down to 14 degrees Fahrenheit. This durable housing relies on an internal zooming chassis structure layout that completely prevents the physical lens body from expanding. Active adventure photographers can safely execute demanding field assignments during heavy mist or winter storms.

OM SYSTEM Mechanical Flange Coupling

The precisely ground metal mount interface pairs tightly to the camera face to prevent any physical movement or lens flexing. This stable integration creates a rigid mechanical flange coupling that easily supports the physical leverage of the 314.3mm long metal barrel. Perfect parallel centering over the digital sensor is strictly maintained for uniform resolution.

Advanced Optical Production Workflows

An integrated built-in mechanical toggle lets shooters engaged in continuous tracking deploy the internal teleconverter instantly to reach a 1000mm equivalent profile. This specialized tactical layout supports efficient commercial field workflows by allowing seamless transitions between extensive framing lengths on set. Settings stay firmly locked whether working handheld or mounted on tripod rigs.

OM SYSTEM Structural Maintenance Safety

Front element maintenance requires using a clean air bulb before performing smooth circular wipes with premium optical cloth structures. Maintaining this care protocol protects the proprietary Z Coating Nano element layers from environmental oil and moisture degradation over long field operations. Includes an Official 1-Year Limited USA Warranty from the manufacturer.
