A constant f/1.8 aperture across the entire 17-40mm zoom range delivers prime-like optical performance in a weather-sealed, 535g body. Its 11-blade diaphragm and Super Multi-Layer Coating produce smooth bokeh with suppressed flare, while the HLA motor provides fast, quiet autofocus for hybrid shooting. This lens is best for portrait and event photographers on Fujifilm X-mount who need a bright, versatile standard zoom without carrying multiple primes.
