Fujifilm's weather-resistant APS-C supertele — 107-457mm equivalent with OIS and linear motor AF.
The Fujifilm XF 70-300mm f/4-5.6 R LM OIS WR was released in 2021 as the mid-range telephoto zoom for the Fujifilm X APS-C system, providing a 107-457mm full-frame equivalent range with LM (Linear Motor) AF, OIS, WR, and an R aperture ring. At 580g it is lighter than the XF 100-400mm while providing equivalent DX-crop reach at the long end for most wildlife and sports applications. WR enables outdoor use with compatible sealed X bodies.
The optical design uses 17 elements in 12 groups, including ED elements. Nine aperture blades produce smooth bokeh. The 67mm filter thread is the XF telephoto mid-range standard. At 580g the lens is moderate for its zoom range. Minimum focus distance of 0.83m throughout the zoom range. OIS provides handheld stability. LM linear motor enables fast, near-silent AF tracking. WR sealing requires a sealed X-series body. R aperture ring provides tactile aperture control. Variable aperture from f/4 at 70mm to f/5.6 at 300mm.
The 107-457mm equivalent range covers the full practical outdoor telephoto spectrum for birds, wildlife, and sports on APS-C. The Linear Motor enables smooth, near-silent focus pulls for wildlife video that older-motor telephoto zooms cannot achieve cleanly. OIS and WR extend the operating envelope for outdoor sessions in variable conditions. The 0.83m MFD throughout the range enables close telephoto compositions that many comparable zooms with longer MFDs cannot achieve.
On the used market the XF 70-300mm R LM OIS WR is available at mid-range XF telephoto pricing. Condition checks: LM motor smoothness in video AF mode, OIS engagement, WR sealing at zoom barrel, R aperture ring click consistency, and front element for marks. The XF 100-400mm provides longer reach with PRO optical quality at higher cost. Compatible with all Fujifilm X-mount bodies; WR requires a sealed X-series body.
