Circular fisheye for EOS M

The Venus Optics Laowa 4mm f/2.8 is a manual-focus circular fisheye built for Canon EOS M mirrorless cameras. It produces a round 210-degree image that covers the full sensor circle, making it a specialist tool for creative photographers and VR content creators who need extreme wide-angle coverage in a tiny package.

210-degree field and close focus

The 210-degree angle of view lets you shoot a full 360-degree spherical panorama in only two or three frames, saving stitching time for virtual tours. A close focus distance of 3.1 inches (8 cm) allows exaggerated foreground detail while keeping the ultra-wide perspective, useful for action sports or immersive interiors. Low-light work is supported by the fast f/2.8 maximum aperture.

Drone-compatible 135 g design

At 135 g (4.8 oz) the lens is light enough for many gimbal drones, opening aerial VR and unique top-down circular perspectives that heavier fisheyes cannot safely carry. The compact barrel adds minimal bulk to a mirrorless kit, so it stays practical for handheld vlogging, skateboarding footage or all-day event work.

Questions about this item

Will the 4mm f/2.8 Circular Fisheye cover the APS-C sensor on my existing Canon EOS M body without vignetting?

The lens is built specifically for the Canon EOS M mount and projects a circular image across the APS-C frame, giving a 210-degree field of view with vignetting only at the circle edges.

How can I verify the 210-degree field of view is working correctly after mounting the lens?

Shoot a flat wall from a known distance; the resulting circular image should span the full sensor width, confirming the 210-degree coverage.

Does the package include a lens hood or protective filters, or do I need to buy them separately?

The circular fisheye design prevents a traditional hood; no screw-in filters fit the front element, so only front and rear caps are supplied.
