You Can Now Buy a 4.9mm f/3.5 Lens That Sees Behind Itself for $39,000

If you have deep pockets and want to venture to the edge of what’s possible in ultra-wide lenses, check out the new C-4 Precision Optics 4.9mm f/3.5 Hyper Fisheye. It’s the world’s widest-ever fisheye lens, so wide that it can see behind itself, and it can now be yours for the low price of $39,000.

The lens was first unveiled back in February 2019 by LensRentals founder Roger Cicala, who created C-4 Precision Optics as an April Fool’s joke back in 2015 before turning it into a real brand.

The C-4 Precision Optics 4.9mm f/3.5 has a ridiculously wide 270-degree field of view and captures fully-circular fisheye images. It’s designed for full-frame Sony E-mount cameras.

The 270-degree field of view means the lens can literally see behind itself.

Build-wise, the lens “looks like a spaceship beaming up your camera.” The 28.6-pound (13kg) lens comes with its own extendable tripod legs and a cheese plate, and the camera is mounted in the interior space. To shoot horizontally, you’ll need to mount the cheese plate (rather than the camera or lens) to a support system.

“This lens will not work well in situations that don’t allow for heavy-duty tripod mounting on account of the large amount of glass required to make this wide-angle feat possible,” LensRentals writes. “This is a mount the camera on the lens kinda situation.”

Containing five extra-low dispersion elements to combat chromatic aberrations, the 4.9mm f/3.5 lens was designed for full-dome imaging, virtual reality, and 360-degree video applications.

Here’s a sample circular fisheye photo captured with the lens:

“The closest thing that’s existed to this is the 1970s classic Nikkor 6mm f/2.8 fisheye, which gave a 220-degree field of view, weighed 5 kg, and can be rarely found for $100,000 and up these days,” Cicala says. “The C-4 optics lens weighs every bit as much as the Nikkor, but should be far sharper, have less distortion and vignetting, and cost somewhat less than those do today.”
