Fujinon GF 45mm f/2.8 R WR Review

The Fujinon GF 45mm f/2.8 R WR is a compact wide-angle prime for Fujifilm's medium format G-mount system. At roughly 36mm equivalent in full-frame terms, it occupies a versatile focal length that suits environmental portraiture, street, and landscape work. The f/2.8 maximum aperture is modest but typical for medium format glass, balancing size, weight, and optical performance. The WR designation confirms weather-resistant construction, a practical feature for field shooting in challenging conditions.

Priced under two thousand dollars, this lens sits in the more accessible tier of the GFX lineup, making it an appealing option for photographers building out a medium format kit without the premium cost of faster or more specialized optics. The 45mm focal length often serves as a workhorse in medium format systems, offering flexibility across multiple genres without the bulk of longer telephoto designs. For GFX shooters looking for a lightweight, weather-sealed wide-angle that covers the essentials, this lens fills a clear gap in the system.
