9mm f/2.8 Zero-D Nikon ZEAN  6940486701814

Combining an ultra wide-angle field of view with a particularly compact design, this Laowa 9mm f / 2.8 Zero-D from Venus Optics is a Nikon Z-mount lens that offers a focal length equivalent to 13.5mm. Being a Zero-D lens, the optical design of this 9mm f / 2.8 is specifically designed to limit distortion for clear and accurate representations of landscapes and architectural subjects. The optical construction also incorporates a pair of aspherical elements and three ultra-low dispersion elements to control spherical and chromatic aberrations for improved sharpness and reduced color fringing. A Frog Eye coating has also been applied to repel dust and moisture from the front lens element to benefit from working in harsh environmental conditions. Its sleek, lightweight design fits perfectly into mirrorless bodies and is ideal for everyday shooting and gimbal use. In addition, a petal-shaped hood is also incorporated into the lens

The straight design makes subjects with minimal distortion to suit landscape and architectural applications.
Three elements with very low dispersion reduce chromatic aberrations and color fringes for greater clarity and color neutrality. There are also two aspherical elements to limit spherical aberrations for better sharpness.
A Frog Eye coating has been applied to repel both dust and moisture for added protection when working in adverse conditions.
The manual focus design offers a minimum focus distance of 4.7 ".
The integrated petal-shaped lens hood protects the lens from stray light to reduce flare and ghosting, and also protects the front elements from accidental bumps.
