Venus Optics launches tiny 4.5-10mm fisheye zoom for APS-C cameras

Venus Optics just made fisheye shooting feel a lot less like a special occasion. The new Laowa 4.5-10mm f/2.8 CF Zoom Fisheye is small enough to disappear in a bag, but wide enough to turn a cramped room, a skate session, or a travel scene into something that looks aggressively warped on purpose.

At 4.5mm, the lens goes circular and hits a 180-degree field of view on APS-C and Micro Four Thirds bodies. Zoom it to 10mm and the look stretches into a diagonal fisheye that fills the frame instead of floating inside it. That transition is the whole point here: one lens covers the goofy, full-circle fisheye trick and the more usable, frame-filling version without forcing you to swap glass.

The practical stuff is what makes this launch interesting for real-world shooting. The lens is manual focus, but it is parfocal, so focus stays put while zooming, which matters far more for video than spec-sheet copy usually admits. The constant f/2.8 aperture keeps exposure steady across the range, and the minimum focusing distance is just 10cm, which means you can get absurdly close and still keep the scene under control. Venus Optics lists mounts for Sony E, Fujifilm X, Nikon Z, Canon RF, Canon EF-M, L-Mount, and Micro Four Thirds, so this is not a weird one-system novelty.

Size is the other reason this lens stands out. PetaPixel measured it at 68.9 by 59.3mm and 338 grams, about the size of a small muffin. That makes the Laowa 4.5-10mm f/2.8 CF Zoom Fisheye a much easier lens to justify for travel, handheld work, and gimbal rigs than the bigger fisheyes that tend to live in the “fun, but only if you planned for it” category. At $399, Venus Optics is not pricing it like a luxury toy either. It is aiming squarely at creators who want a creative look that can actually stay in the bag.

That fits Venus Optics’ own identity. The company says it was formed by a group of industry experts and photographers to make “unique, practical & affordable” lenses, and this one lands right on that line. It also follows the full-frame Laowa 8-15mm f/2.8 FF Zoom Fisheye from 2025, which showed the same circular-to-diagonal fisheye trick in a larger format. The difference now is the footprint. This is the kind of lens that makes fisheye less of an occasional stunt and more of a daily carry option, which is exactly why it feels useful rather than merely strange.
