Sigma 15mm f/1.4 DC Contemporary Lens for Fujifilm X Mount In More Detail
Optical Design and Wide-Angle Perspective
The lens uses an 11-element, 13-group construction incorporating one FLD element, three SLD elements and three aspherical elements. This configuration maintains strong edge consistency and reduces aberrations that are commonly visible in wide-angle lenses.
On Fujifilm X cameras, the 15mm focal length provides an angle of view of approximately 86.9°, offering a broad field suitable for landscapes, architecture, interiors and environmental portraits.
Control of sagittal coma flare has been prioritised, which is important when photographing night skies or scenes with point light sources. Sharpness remains consistent across the frame, even when shooting at the maximum aperture of f/1.4.
Aperture and Low-Light Capability
The f/1.4 maximum aperture allows more light to reach the sensor compared to slower kit zoom lenses. This supports lower ISO settings in dim conditions and provides flexibility when shooting indoors or after sunset.
The nine-blade rounded diaphragm maintains circular aperture when stopping down, helping background highlights appear smooth and natural. Minimum aperture extends to f/16 for greater depth of field when required.
Close Focusing and Framing
The minimum focusing distance is 17.9cm with a maximum magnification ratio of 1:7.9. This allows subjects to be framed more closely than many traditional wide-angle lenses, expanding creative options for foreground emphasis and detailed compositions.
Autofocus and Video Performance
Autofocus is driven by a stepping motor that moves a lightweight focus group with precision. This enables fast and accurate focusing for still photography while maintaining smooth transitions for video recording.
Focus breathing has been reduced to limit visible angle-of-view changes when adjusting focus during video capture. The compact 225g build and wide angle of view also make it suitable for gimbal-based shooting, cinematic video production and solo content creation, including webinars and live commerce setups.
The Fujifilm X version includes an aperture ring for direct exposure control on the lens barrel, supporting intuitive manual adjustments.
Construction and Design
The Fujifilm X version weighs 225g and uses a 58mm filter thread. Its compact form improves portability compared to the earlier 16mm f/1.4 DC DN while maintaining strong optical performance.
The lens includes dust- and splash-resistant sealing and a water- and oil-repellent coating on the front element for greater durability in outdoor use.
