Lens manufacturer Venus Optics has created one of the most unusual lenses you will ever see. It is called the Laowa 24mm f/14 Replay 2x Macro lens and its design is more similar to the barrel of a gun than a camera lens. This beast was spotted at photokina 2016.
It is designed specifically for photographing “shy” subjects. It has an extra long barrel that allows you to keep your distance.
The full-frame lens features a 2:1 maximum macro reproduction ratio and is said to work in “extreme” temperatures and conditions, although details of the exact temperature range and capable environments is unspecified.
The lens would be available sometime in 2017 for both Nikon and Canon without any information on pricing yet.
