Venus Optics has officially announced the Laowa RF (RF-S) 4.5-10mm f/2.8 CF Zoom Fisheye lens, expanding its lineup for mirrorless camera systems. The lens is designed for both APS-C and Micro Four Thirds formats, targeting creators who require ultra-wide perspectives in a compact form factor. According to the announcement, the lens offers a zoom range from 4.5mm to 10mm, enabling a transition from a full 180° circular fisheye view to a frame-filling diagonal perspective.
The lens is described as a compact “muffin-lens,” a term used by Venus Optics to highlight its small, portable design without specifying exact dimensions or weight. This characterization emphasizes ease of use for handheld shooting, gimbal work, or travel scenarios where space and weight are considerations. The constant f/2.8 aperture across the zoom range suggests consistent low-light performance and depth-of-field control throughout the focal range.
Optically, the lens incorporates a close-focus (CF) mechanism, allowing for near-distance shooting while maintaining image quality at extreme wide angles. This feature benefits creators seeking immersive foreground emphasis in video or stills, particularly in tight interior spaces or dynamic action sequences. The RF and RF-S mounts indicate compatibility with Canon’s mirrorless ecosystem, though the lens is also engineered for Micro Four Thirds use, broadening its appeal across platforms.
While the announcement does not detail specific optical elements, coatings, or distortion correction technologies, it confirms the lens delivers the characteristic fisheye look with zoom flexibility—a rare combination in the interchangeable lens market. Venus Optics continues to focus on niche focal lengths and creative tools, and this release aligns with its strategy of addressing underserved segments in the creator community.
Pricing, availability, and regional release schedules were not included in the source material. Creators interested in the Laowa RF 4.5-10mm f/2.8 CF Zoom Fisheye are advised to monitor official Venus Optics channels or authorized retailers for further updates. The lens joins a growing selection of third-party optics supporting Canon’s RF and RF-S mounts, reinforcing the expanding lens ecosystem for APS-C mirrorless users.
