Sigma boosts Fujifilm range with 100-400mm zoom, fast 23mm prime

Sigma has announced that the 100-400mm F5-6.4 DG DN OS | Contemporary lens will soon be available for Fujifilm X-mount cameras, adding to the line-up of X-mount lenses from the Aizu, Japan, based manufacturer.

Previously, the lens was available in Sony E and L mounts and we rate it very highly. Sigma has also announced the availability of the 23mm F1.4 DC DN | C lens for X mount. This lens is already on sale in Sony E and L mounts.

The Sigma 100-400mm F5-6.3 DG DN OS | Contemporary has been optimised for use on Fujifilm APS-C cameras and can take advantage of the crop sensor to give an equivalent focal range of roughly 150-600mm. This optimisation has also increased its effective optical stabilisation from four to five stops.

Owing to differences in camera software between Fujifilm and Sony E-mount/L-Mount systems, the AF/MF Switch and AF-L button have been replaced with a new AF Function Setting switch and AF Function button. The switch changes the Function Button on the lens between AF and AF-L modes.

The lens also supports dual action zoom, which means it can be zoomed or out by turning the zoom ring, or by pushing and pulling the lens hood. You can also set the AF Limiter switch on the side of the lens to control the focus range, to reduce ‘hunting’ when shooting busy scenes and when subjects are a set distance away.

‘Macro and portrait photographers can take advantage of the 1:4.1 magnification ratio and 160cm minimum focus distance at 400mm to capture close-up images with creative background compression,’ Sigma adds.

Fast 23mm prime for X-mount, too
