With a 396mm equivalent focal length on Fujifilm’s GFX medium-format system, this lens combines fast linear motor autofocus, 6-stop optical stabilization, and full weather-sealing in a 1375g body. Its 7 ED elements deliver sharpness across the frame, while the 9-blade rounded aperture produces smooth bokeh in a portable design. This lens is ideal for wildlife and sports photographers needing silent, weather-resistant performance on a medium-format platform.
