Rokinon 7.5mm f/3.5 Ultra Wide-Angle Fisheye Lens (Micro Four Thirds)
The Rokinon 7.5mm f/3.5 Ultra Wide-Angle Fisheye is a specialized, ultra-compact manual prime lens designed exclusively for Micro Four Thirds (M4/3) mirrorless cameras. Delivering an expansive and stylized 180° angle of view, this lens produces a dramatic, circular fisheye distortion that instantly elevates creative action sports, architectural interiors, and abstract landscapes into captivating, larger-than-life compositions.
Optical Clarity & Flare Control
Hybrid Aspherical Design: The optical architecture is engineered with precision hybrid aspherical lens elements. These specialized optics correct spherical aberrations and minimize edge-to-edge distortion, ensuring sharp, highly defined image resolution across your entire 180° frame.
Super Multi-Layer Coating: A multi-layer optical coating has been meticulously applied to individual elements to suppress surface reflections, ghosting, and lens flare. This preservation of contrast is critical for ultra-wide lenses, which frequently catch harsh incident light from the edges of the scene.
Built-In Petal Lens Hood: Features a permanently attached, built-in petal-type lens hood that shades the prominent, bulbous front element from stray light while providing physical protection against accidental bumps.
Ultra-Close Manual Focus Performance
Svelte & Lightweight Profile: Exceptionally compact and lightweight, this manual focus prime mirrors the portable philosophy of the Micro Four Thirds system, making it an effortless addition to any travel setup.
Intimate 4″ Close-Focusing: Boasts an incredibly tight minimum focusing distance of just 4 inches (9 cm). Getting right up to your subject allows you to combine intense close-up detail with the camera’s sweeping, ultra-wide distortion for surreal and highly dynamic photographic effects.
Condition Note (Missing Front Cap)
This specific lens is fully functional with smooth manual focus ring operation and clean electronic-free mechanics. Please note the following accessory detail:
No Front Cap Included: This unit does not include a front lens cap. Because the lens has a bulbous, protruding front glass element and a built-in hood, we highly recommend storing the camera inside a padded pouch or wrapping the lens head in a soft microfiber cloth when traveling to keep the optics safe from scratches. The rear mount cap is included.
