AstrHori’s New 6mm f/2.8 Fisheye Lens

AstrHori has added a rather unusual lens to its lineup: a 6mm f/2.8 circular fisheye for full-frame mirrorless cameras. With a 220-degree field of view, it’s about as wide as lenses get, producing a fully circular image inside the frame. The lens is ment for photographers and videographers looking for something more experimental, whether that’s night skies, exaggerated landscapes, architectural shots that lean heavily into distortion or simply good old skating videos.

The lens design is fairly straightforward. It’s manual focus only, with 10 elements in eight groups and an eight-bladed aperture that runs from f/2.8 to f/16. It focuses down to just over three inches (0.08 meters), which opens the door for some dramatic close-ups with plenty of perspective stretch. The compact barrel measures 61mm in length and 64.8mm in diameter, and depending on the mount, it weighs around 340 grams. Unsurprisingly, the lens doesn’t support filters given the large front element and extreme angle of view.

As a circular fisheye, the AstrHori 6mm produces heavy distortion by design, filling the frame with a perfectly round image and leaving black borders around it. It’s not going to be an everyday lens of course, but it fills a gap for those who want to experiment. The lens is available for Sony E, Canon RF, Nikon Z, and L-Mount, priced at $299.
