Laowa Drops a $399 Fisheye Zoom That’s Faster Than Canon’s $1,400 — Seven Mounts

Key Takeaways

• Venus Optics announced the Laowa 4.5-10mm f/2.8 CF on May 21 — a fisheye zoom with constant f/2.8 across the entire focal range, a class first.
• Priced at $399 across all seven mounts (Sony E, Nikon Z, Canon RF, Canon EF-M, Fujifilm X, L-Mount, Micro Four Thirds) — well under half what Canon and Nikon charge for their fisheye zooms.
• At 4.5mm the lens delivers a 180-degree circular fisheye image; zoom to 10mm and the same 180-degree field projects as a diagonal fisheye, all without losing focus thanks to a parfocal design.
• Manual focus only, 338 g, 0.1 m minimum focus distance, available now at B&H and the Laowa store.

Fisheye zoom lenses are one of the strangest blanks on the optical map. Almost every fisheye in production is a fixed focal length — Sigma’s 4.5mm, Rokinon’s 8mm, Brightin Star’s recent $66 10mm and $140 7.5mm — and the few zooms that exist (Canon EF 8-15mm f/4L, Nikon 8-15mm f/3.5-4.5E, Tokina 10-17mm) were all built years ago for DSLR mounts and asked $500 to $1,400 at launch.

So when Venus Optics quietly listed the Laowa 4.5-10mm f/2.8 CF on May 21, it landed in a category that had not seen a new entry in years — and it brought specs no fisheye zoom has matched before.

The first fisheye zoom that is also f/2.8

Constant f/2.8 across a fisheye zoom range is genuinely new. Canon’s EF 8-15mm f/4L sits a full stop slower. Nikon’s 8-15mm f/3.5-4.5E gives up between one and one-and-a-third stops by the long end. The Tokina 10-17mm starts at f/3.5 and ends at f/4.5. The Laowa is the first to deliver f/2.8 from corner to corner of the zoom ring, which matters most in the situations fisheyes earn their keep — astrophotography under genuinely dark skies, indoor real-estate work without artificial lighting, action and surf rigs at dusk, and anywhere the photographer is fighting motion blur as much as exposure.

That advantage compounds at $399. The closest comparable lens, Canon’s EF 8-15mm f/4L Fisheye USM, still lists around $1,400 — and it is an EF-mount lens that requires an adapter on every modern Canon body. The Laowa undercuts it by 71% and comes native to seven mirrorless systems out of the gate.

180 degrees that travels with the zoom

The unusual optical trick is what happens to the image circle as the zoom shifts. At 4.5mm the lens projects a circular fisheye — a perfect disc of image floating inside black corners, the full 180-degree hemisphere captured in one shot. Twist the ring to 10mm and the same 180-degree field of view is preserved, but the image circle has grown to fill the APS-C frame edge to edge as a diagonal fisheye. Photographers who used to swap between a circular and a diagonal fisheye for different shots now have one lens that does both, and a parfocal optical design that keeps focus locked while the zoom moves.

Seven mounts at one price

The mount list reads like a checklist of every system that did not previously have a native fisheye zoom option: Sony E, Nikon Z, Canon RF, Canon EF-M, Fujifilm X, Leica L, and Micro Four Thirds. Every mount ships at the same $399 price — Venus Optics has not split the lineup by system, which is unusual in itself. RF, Z, and E shooters now have a fisheye zoom that does not require an adapter for the first time.

The CF designation refers to Laowa’s Cine Focus build. That means a de-clicked, smoothly damped aperture ring and industry-standard focus marks on the barrel — features built for video shooters and gimbal operators rather than stills photographers. There is no autofocus on this lens. Manual focus is the only option, which on a fisheye is rarely a constraint because depth of field at f/2.8 on a 4.5-10mm lens covers most of what is in front of the camera anyway.

The other numbers that matter

The optical design uses 13 elements in 9 groups, including four extra-low dispersion elements and one ultra-high-refraction element — Laowa’s usual configuration for keeping chromatic aberration controlled on fast wide lenses. The lens weighs 338 grams and measures 59.3 mm long, which is closer to a pancake prime than a fisheye zoom in physical footprint. Minimum focus distance is 0.1 meters — close enough to push the front element into the subject for the heavy distortion shots that make fisheyes a creative tool.

Pricing is uniform at $399 across all mounts, and the lens is available now through B&H Photo and the official Laowa store rather than a pre-order window. That contrasts with most third-party launches, where the announcement comes weeks ahead of shipping.

Who actually buys this

The target buyer is anyone whose shots have historically required carrying two fisheye primes — one circular, one diagonal — and who is now interested in collapsing that to a single lens with a brighter aperture for a quarter of the combined cost. That includes astrophotographers chasing the Milky Way arch, real-estate and Airbnb shooters who need to make small rooms feel large without distortion correction in post, skate and surf videographers running gimbals, and creators producing 360 and VR content who rely on circular fisheyes as source frames for stitched panoramas. On Micro Four Thirds the lens behaves more like a 9-20mm full-frame equivalent — a useful range even when the fisheye projection is corrected to rectilinear in post.

Frequently Asked Questions

Is the Laowa 4.5-10mm f/2.8 CF the first fisheye zoom lens?

No, but it is one of only a handful ever made. Canon, Nikon, Tokina, and Pentax have all shipped fisheye zooms in the past, but those were DSLR-mount lenses with slower variable apertures (f/3.5-4.5 or f/4 constant). The Laowa is the first fisheye zoom with constant f/2.8 and the first designed natively for modern mirrorless mounts.

Does the lens have autofocus?

No. The Laowa 4.5-10mm f/2.8 CF is manual focus only. On a fisheye lens that constraint is usually moot because the depth of field at any reasonable aperture covers most of the scene from a meter to infinity.

Will the lens work on full-frame cameras?

The Laowa 4.5-10mm projects an APS-C image circle, so on full-frame bodies it will either trigger automatic APS-C crop mode or produce strong vignetting at the corners. The mount lineup includes APS-C cameras like the Sony a6700, Fujifilm X-T5, and Nikon Z fc as the intended targets, along with the smaller Micro Four Thirds sensor.

What does CF stand for in the lens name?

CF refers to Laowa’s Cine Focus designation, which signals a de-clicked aperture ring (for smooth iris pulls during video) and industry-standard focus markings on the barrel for use with follow-focus rigs.

Bottom line

Fisheye zooms are a niche of a niche, but the Laowa 4.5-10mm f/2.8 CF makes the math work for a wider audience than the previous options ever did. A constant f/2.8 across the whole zoom range, parfocal optics, native fitments on seven mirrorless mounts, and a $399 price that undercuts Canon’s nearest competitor by 71% changes the answer to “should I just buy a fisheye prime instead?” in a way no third-party launch in this category has before.
