Lens Description: Presenting a super wide field of view, the GF 23mm f/4 R LM WR from Fujifilm is an ultra-wide 18mm-equivalent prime designed for the G-mount GFX camera system. Ideally suited for architecture and interior photography, the lens's design employs a pair of aspherical elements to control distortion and spherical aberrations for accurate rendering, and a series of low dispersion elements are also featured for improved color accuracy and clarity. Additionally, a Nano GI coating has been applied to suppress lens flare and ghosting for improved contrast and color. Balancing the optical attributes, the lens also utilizes a linear AF motor with an internal focusing design for quick and quiet focusing performance, and a manual aperture ring also avails intuitive exposure adjustment and a Command position permits making camera-based aperture selections. Additionally, the lens is also dust-, freeze-, and weather-resistant for use in trying environmental conditions.
