If you like fisheye lenses, here’s a real treat. C-4 Precision Optics 4.9mm f/3.5 Hyper Fisheye pretty much reveals in its name what it’s capable of. The “hyper fisheye” lens offers a 270° field of view, or in other words- it can see behind itself. But this impressive feature comes with a price – and the price is $39,000.
LensRentals has posted some fantastic teardowns with impressive regularity over the years, but it’s rare that we see them put something together. They thought that it was about time to show off building a lens, after shooting timelapse of tearing down the massive C-4 Optics 4.9mm f/3.5 Hyperfisheye prototype lens from scratch, LensRentals founder, Roger Cicala posted a detailed write up of the lens being reconstructed from scratch.
Unlike most of the lenses today, this lens is all mechanical. There’s no fancy autofocus, image stabilisation or electronics to deal with. And that short 4.9mm focal length offers an insane 270° field of view. Yes, it can see behind itself!
