Laowa Expands Ultra-Wide Horizons with New CF 4.5-10mm F2.8 Zoom Fisheye for APS-C
Laowa continues to push the boundaries of unconventional optics with the introduction of its latest specialized tool: the CF 4.5-10mm F2.8 Zoom Fisheye. Designed specifically for APS-C sensor bodies, this lens offers a unique combination of extreme wide-angle perspectives and zoom versatility, catering to photographers and creators looking to break away from standard focal lengths.
Extreme Perspectives: The 180-Degree View
The standout feature of the CF 4.5-10mm is its ability to capture an incredibly wide field of view. At its shortest focal length of 4.5mm, the lens provides a 180-degree angle of view. This extreme breadth is characteristic of a circular fisheye perspective, allowing users to capture immersive, hemispherical imagery that traditional lenses cannot replicate.
Unlike fixed focal length fisheye lenses, the zoom capability allows photographers to transition from the extreme 4.5mm wide-angle view to a 10mm perspective. This range provides a versatile creative tool for capturing unique architectural, landscape, and abstract compositions.
Advanced Optical Engineering
To maintain image quality across such an extreme focal range, Laowa has utilized a sophisticated optical design. The lens is constructed with 13 elements arranged in 9 groups. To combat chromatic aberration and ensure clarity, the build incorporates:
- 4 extra-low dispersion (ED) elements to minimize color fringing.
- A single ultra-high refractive index element to optimize light transmission and performance.
While the lens is strictly a manual focus optic, the design remains highly functional for wide-angle applications. At extremely short focal lengths, the depth of field is naturally expansive, making manual focusing a forgiving and straightforward process for most shooting scenarios.
Compact Design and Mount Compatibility
Despite its specialized optical complexity, Laowa has prioritized portability. The CF 4.5-10mm is remarkably compact for a zoom fisheye, measuring just 59.3mm in length with a diameter of 68.9mm. Weighing in at 330g, it is a manageable addition to a creator’s kit.
Recognizing the diverse landscape of mirrorless and DSLR systems, Laowa has released the lens across several major mounts. It is available for:
- Sony E-mount
- Fujifilm X-mount
- Nikon Z-mount
- Canon RF-mount
- Canon EF-M-mount
- L-Mount
- Micro Four Thirds
