A versatile ultra-wide angle zoom lens delivering expansive creative possibilities for Nikon F mount cameras. This EX series lens covers 15-30mm, providing extreme wide-angle coverage ideal for landscapes, architecture and environmental portraiture. Featuring 17 lens elements with aspherical designs at both the front and rear groups, it minimises distortion and optical aberrations for sharp, clear imagery. The constant f/3.5-4.5 aperture remains consistent throughout the zoom range, whilst the dual-focus system with inner focus mechanism ensures smooth operation without rotating the focus ring during autofocus. With a minimum focusing distance of 30cm throughout the entire zoom range and an integrated metal hood, this lens is built for professional-grade ultra-wide angle work.
