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 (2021) is Fujifilm's first native X-mount telephoto to reach 300mm (457mm equivalent). It fills the gap between the XF 55-200mm and the larger XF 100-400mm.
Good centre sharpness throughout. Well-controlled CA from ED and Super ED elements. Linear motor AF is fast and near-silent. OIS provides approximately 5.5 stops. Noticeably sharper than the older XF 55-200mm.
Fujifilm X mount, 67mm filter thread. WR = weather resistant with sealing at 11 points. Manual aperture ring. Internal zoom. No teleconverter compatibility. 83cm minimum focus gives 0.33x at 300mm.
Moderately available used. Check OIS for smooth operation and inspect weather sealing gaskets at mount. The XF 100-400mm offers more reach but is heavier and pricier. For most users this is the best reach-weight-price balance in X-mount.
