Sigma launches its first-ever telephoto zoom for Fujifilm X-mount cameras
Sigma is introducing its first-ever telephoto for the Fujifilm X-mount. The Sigma 100-400mm f/5-6.4 DG DN OS | C supertelephoto Zoom will join the existing five lenses that Sigma has already announced for the Fujifilm APS-C mirrorless system.
When the 1.5x crop factor is taken into account, the new Sigma 100-400mm gives an effective focal length range of 150-600mm - making it an attractive choice for bird photography, airshows and safaris.
The new zoom has been adapted from the full-frame Sigma 100-400mm f/5-6.4 DG DN OS | C which was launched for Sony FE and L-mount mirrorless cameras in 2020.
Much of the specification for the Fujifilm X-mount lens remains the same, despite not needing such a wide imaging circle. It is constructed from 22 elements in 16 groups, with a 9-blade circular diaphragm. It weighs 1135g (40oz), and has a 67mm front filter thread. A tripod mount (TS-111) is available as an optional extra - this replaces the protective cover (PT-31) which is otherwise fitted to the lens.
The new Fujifilm version of the 100-400mm F5-6.3 DG DN OS features a unique AF Function Setting switch and AF Function button, not found on the L-Mount and Sony E-mount versions. The performance of the optical image stabilizer has also been improved offering a five-stop effect (up from four stops with the Sony and L-mount versions).
The Fujifilm version retains the same high-quality FLD and SLD glass elements, which promises sharp images across the whole frame and throughout the entire zoom range. Other features include a two-mode optical stabilizer, focus limiter switch and dual action zoom.
Existing Sigma lenses for the X-mount system are the 16mm F1.4 DC DN | C, 30mm f/1.4 DC DN | C, 56mm f/1.4 DC DN | C, and 18-50mm f/2.8 DC DN | C. The more recently announced Sigma 3mm F1.4 DC DN | C goes on sale on September 23.
