New AF Focus button and AF Focus Switch

Due to differences in camera software, the lens features a new AF Function Setting switch and AF Function button, replacing the AF/MF Switch and AFL buttons found on the L-Mount and Sony E-mount. The switch can be toggled to change the function of the button between AF Lock and AF activation on the fly.

Shoot fast paced action and close-up macro

The SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary supports dual action zoom. The lens can be zoomed in or out by turning the zoom ring for precise control, or by pushing and pulling the lens hood to quickly react to fast paced action. Set the AF Limiter switch on the side of the lens to control the focus range, to reduce lens 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.

Improved Optical Stabilisation

As the lens has been optimised for Fujifilm cameras, the stabilisation effect has increased from four to five steps. This can allow users to shoot in lower light conditions with slower shutter speeds, with improved results.
