Fish(-eye) scales -[ HMM ]-

Distance and aperture scales on a Rokinon 8mm ƒ/3.5 fisheye lens. The Rokinon brand is made by South Korea-based Samyang Optics.

 

The quality of this lens is quite good for a low-cost offering. To keep the cost low, however, it's a purely mechanical design with manual focus and aperture. It's still very capable of delivering decent results.

 

The diameter at the widest part shown here, the aperture ring, is just under 2¾ inches (69.9mm).
