Lensbaby Circular Fisheye 5.8mm f/3.5 Lens


The Circular Fisheye is a 5.8mm f/3.5 lens. With this Circular Fisheye lens, Lensbaby now offers photographers with crop sensor cameras a fun and affordable way to create circular images that transform the world around them. The Circular Fisheye is great for capturing the scale of endless landscapes and big events, fun self-portraits, quirky shots of pets or friends, creating extreme perspective, and experimenting with unique lens flare. This manual lens has built-in aperture control ranging from f/3.5-22 and features an ultra-wide 5.8mm focal length. It is capable of capturing a 185 degree angle of view and focusing from 1/4 inch in front of the lens to infinity. That extreme close-focus paired with the incredibly wide 5.8mm focal length produces other-worldly distortion with exceptional sharpness throughout.

Circular fisheye lenses produce an image that is circular, surrounded by black. The images above were shot with the Circular Fisheye lens on an APS-C sensor camera: this lens was optimized to produce a full-circle fisheye image on these cameras. Lensbaby deliberately designed the internal lens barrel of the Circular Fisheye to be reflective allowing bright sources of light to form a halo of colorful flare around the image, as seen in the image below left. In flatter light, parts of a scene can also be reflected into the area surrounding the image, as seen in the image below right.

This lens has absolutely NO HOTSPOTS with any of our infrared filters!
