ADDRESS LENS DESIGN CHALLENGES

Ultra-wide optics can by nature complicate accessory use

Lenses in the 12mm range and fisheye optics commonly have bulbous front elements, which is an unavoidable design factor. This can prohibit the use of screw-in filters and standard filter holders. Third-party holders can be sourced, such as the Lee sW150 Mark ii system or nisi s5, which enable filters to be mounted on the AF-s nikkor 14-24mm f2.8g ed for example.
