Olympus M.Zuiko ED 150-400mm F4.5 TC1.25X IS PRO – Super Telephoto Zoom, Built-in Teleconverter, Optical Stabilization, Weather Sealing
The Olympus M.Zuiko ED 150-400mm F4.5 TC1.25X IS PRO redefines professional wildlife and sports photography by offering an ultra-telephoto zoom lens with integrated teleconverter, class-leading image stabilization, and robust weather sealing. Designed for demanding photographers who require lightweight mobility without compromising reach or optical performance, this lens addresses the challenges of capturing distant, fast-moving subjects in challenging environments. The core technology centers around a precision-engineered optical formula with advanced lens coatings, a built-in 1.25x teleconverter, and a state-of-the-art image stabilization system, making it a standout in the Micro Four Thirds ecosystem.Unlike conventional super-telephoto lenses, the 150-400mm F4.5 TC1.25X IS PRO delivers a full-frame equivalent focal length of 300-1000mm (with teleconverter), all in a remarkably compact and portable form factor. This combination of reach, speed, and agility empowers professionals to shoot handheld in the field, seize fleeting moments, and achieve exceptional image quality rivaling flagship telephoto options from Canon, Nikon, and Sony, but at a fraction of the weight and size.
1. Built-in 1.25x Teleconverter
The integrated 1.25x teleconverter extends the lens’s native 150-400mm range to 187.5-500mm (375-1000mm equivalent), instantly accessible via a side-mounted lever. This eliminates the need to carry and attach separate teleconverters, maintaining optical quality and autofocus speed. This allows photographers to adapt instantly to changing scenes, getting closer to elusive wildlife or distant action without missing a beat.
2. Superior Image Stabilization (IS)
The lens features Sync IS, combining 5-axis in-body stabilization with lens-based IS for up to 8 EV stops of compensation, according to CIPA standards. This surpasses the stabilization performance of most competing telephoto zooms and enables sharp results even at extreme focal lengths or slow shutter speeds. This enables handheld super-telephoto shooting in low light conditions, reducing the need for tripods and supporting creative flexibility in the field.
- Sync IS with compatible Olympus OM-D bodies
- Up to 8 stops of compensation
3. Weather-Sealed PRO Construction
Engineered to IPX1 standards, the 150-400mm F4.5 TC1.25X IS PRO offers comprehensive dustproof, splashproof, and freezeproof protection. All critical seams and controls are sealed, ensuring reliability in rain, snow, and dusty locations. This provides peace of mind for outdoor photographers who need gear that performs flawlessly in unpredictable environments.
4. ED and EDA Glass Elements
The optical design incorporates 28 elements in 18 groups, including ED (Extra-low Dispersion), EDA (Extra-low Dispersion Aspherical), and Super ED elements to suppress chromatic aberration and flare. Advanced Z Coating Nano further reduces ghosting and contrast loss in backlit situations. This ensures consistently sharp, high-contrast images with minimal color fringing, even when shooting into the sun or at maximum zoom.
- 28 elements in 18 groups
- 8 ED, 2 Super ED, 2 EDA elements
- Z Coating Nano anti-reflective technology
5. Fast and Silent Autofocus
The lens employs a high-speed, quiet linear motor for autofocus, optimized for both stills and 4K video capture. Focus acquisition is accurate and nearly instantaneous, even with teleconverter engaged or in low light performance scenarios. This allows sports and wildlife shooters to track unpredictable subjects with confidence and capture decisive moments in silence.
6. Lightweight Magnesium Alloy Barrel
Despite its reach, the lens weighs only 1,875g (4.13 lbs) without tripod mount, thanks to a magnesium alloy chassis and carbon fiber hood. This is dramatically lighter than full-frame equivalents from Canon or Nikon, which typically exceed 3kg. This enables long handheld sessions and greater mobility, ideal for remote fieldwork or travel photography.
- 1,875g (4.13 lbs) weight
- 304.8mm (12 in) length
- Carbon fiber lens hood included
7. Close Focusing and Macro Capability
The lens achieves a minimum focusing distance of 1.3m (4.27 ft) at all focal lengths, delivering a maximum magnification of 0.57x (1.43x with teleconverter, 35mm equivalent). This is exceptional among super-telephoto lenses, allowing near-macro shooting of small wildlife and details. This gives photographers the flexibility to capture both distant subjects and intricate close-ups without changing lenses.
8. Customizable Function Buttons and Focus Limiter
Four L-Fn buttons and a customizable focus limiter switch provide tactile control for critical shooting adjustments. These features support smooth workflow integration and prevent accidental focus hunting in complex scenes. This streamlines operation in the field, enabling photographers to react quickly and stay focused on the action.
9. Fluorine-Coated Front Element
A fluorine coating on the front lens element repels water, oil, and dust, making cleaning effortless and maintaining optical clarity in adverse conditions. This is especially valuable for outdoor and wildlife shooters who frequently encounter mud, rain, or sea spray. This ensures that image quality is preserved, and downtime for lens maintenance is minimized during demanding shoots.
10. Compatibility with Teleconverters MC-14 & MC-20
In addition to its built-in 1.25x converter, the lens is fully compatible with Olympus MC-14 (1.4x) and MC-20 (2.0x) external teleconverters. This extends the focal reach up to a staggering 2000mm (35mm equivalent) while maintaining autofocus and stabilization. This future-proofs the lens for extreme telephoto needs, providing unmatched versatility for specialized applications like birding or lunar photography.
- Works with MC-14 and MC-20 teleconverters
- Maintains AF and IS functionality
- Maximum reach: 2000mm (35mm equivalent)
