Outstanding Image Quality
Sigma reinforces its reputation for premium craftsmanship with an intricate optical structure designed for outstanding image quality. The 100-400mm F5-6.3 DG DN OS Contemporary Lens for Fujifilm X features an incredible 22 glass elements arranged into 16 groups to deliver exceptional resolution and detail-rich clarity across the entire frame. This makeup includes one FLD and four SLD elements to help reduce colour fringing and chromatic aberration. Sigma has also applied a super-multi-layer coating to minimise flare and ghosting, providing users with high contrast and colour-neutral photos even in backlit conditions.
Maximum Versatility
The Sigma 100-400mm F5-6.3 DG DN OS Contemporary lens is also an incredibly versatile option for portrait photographers and macro-style shooters. Thanks to its 1:41 maximum magnification ratio and 112cm minimum focusing distance (or 160cm at 400mm), users can unlock a new world of remarkable detail much closer to the subject. Combined with the impressive f5 maximum aperture, the Sigma 100-400mm F5-6.3 DG DN OS Contemporary lens provides extended control over depth-of-field for striking portraits with creative background compression. Bokeh also looks naturally circular, thanks to the 9-bladed diaphragm.
Ready for Action
To accompany the high-end optics, Sigma includes three upgraded features for smooth, fast, and shake-free operation. The first is a dual-action zoom with an integrated push/pull mechanism for rapid response times and the standard twist ring designed for extra precision. The second improvement stems from the optimisations made for Fujifilm cameras. As an X-mount lens, the image stabilisation effect has increased to a five-stop advantage. This upgrade allows users to shoot in low light conditions with slower shutter speeds without compromising quality. Finally, the lens features a new AF Function Setting switch and AF Function button that users can toggle to change the function between AF Lock and AF activation on the fly.
