A Dual-Perspective Fisheye Zoom in a Tiny Barrel
Venus Optics’ new Laowa 4.5-10mm f/2.8 CF Zoom Fisheye is a rare breed: a fisheye zoom lens that shifts seamlessly from a circular to a diagonal look, yet remains genuinely compact. Designed as an APS-C lens with coverage that also suits Micro Four Thirds cameras, it delivers an ultra wide angle view rated between roughly 175° and 180° across the zoom range. At 4.5mm, it produces a dramatic circular fisheye image; zooming in toward 10mm fills the frame with a classic diagonal fisheye projection. Despite this versatility, the lens stays palm-sized, measuring just 68.9 x 59.3mm and weighing 338g. For creators who want an extreme, creative field of view without hauling bulky glass, Laowa has effectively condensed two specialist optics into one compact camera lens.
From Circular to Diagonal: Two Fisheye Looks, One Workflow
The key appeal of the 4.5-10mm f/2.8 CF Zoom Fisheye is its ability to offer two distinct fisheye aesthetics without swapping lenses. At the shortest 4.5mm setting, the lens renders a circular image with an expansive 180-degree field of view, ideal for crystal-ball style compositions, immersive night skies, or 360° stitching workflows. As you zoom toward 10mm, the projection transitions into a full-frame diagonal fisheye with the familiar sweeping curvature prized in skate, surf and FPV-style footage. Laowa also highlights the option to “de-fisheye” the 10mm end in post, producing a rectilinear-style ultra wide angle frame that is effectively wider than a standard 10mm prime once corrected. That flexibility turns an otherwise niche APS-C lens into a more general-purpose creative tool, especially for shooters comfortable refining their look in software.
Parfocal, Close-Focus and Constant f/2.8 for Hybrid Creators
Beyond perspective tricks, the 4.5-10mm is built with serious video and stills use in mind. Its parfocal optical design maintains focus as you zoom, making smooth in-shot focal length changes possible without refocusing — a rare capability for a manual fisheye zoom at this price tier. The constant f/2.8 aperture keeps exposure consistent throughout the range and offers welcomed flexibility for low-light interiors or night cityscapes. Optically, the lens incorporates 13 elements in 9 groups and stops down to f/22 via a 7-blade diaphragm. The CF badge stands for Close Focus, and the lens lives up to it with a 10cm minimum focusing distance and up to 0.27x magnification. Combined with its ultra wide angle coverage, that lets shooters push in extremely close while still capturing a broad, exaggerated environment around the subject.
Portability, Mount Options and Pricing Open Fisheye to More Shooters
Laowa’s so-called “muffin-lens” form factor is central to the appeal of this compact camera lens. At only 338g and barely taller than many pancake primes, it is an easy match for lightweight APS-C and Micro Four Thirds bodies, gimbal setups and even FPV drones where every gram matters. The manual-focus lens ships in seven mounts: Sony E, Fujifilm X, Nikon Z, Canon RF, Canon EF-M, L-Mount and Micro Four Thirds. As an APS-C lens, it requires crop modes on full-frame bodies and will not provide a 180° circular image when used outside its intended sensor coverage. Priced at USD 399 (approx. RM1,870), it undercuts many specialist fisheye options while replacing the need for separate circular and diagonal lenses. For budget-conscious photographers and filmmakers, that combination significantly lowers the barrier to exploring extreme ultra wide angle creativity.
