Sigma 15mm f/1.4 DC Contemporary Lens for Canon RF Mount Summary
The Sigma 15mm f/1.4 DC Contemporary Lens for Canon RF Mount is a large-aperture wide-angle prime designed for APS-C format Canon EOS R mirrorless cameras. It joins Sigma’s F1.4 DC Contemporary series of RF lenses and offers a focal length equivalent to approximately 24mm on full-frame, delivering a wide yet natural perspective suited to everyday photography and video.
Positioned within the Contemporary lens range, unlike Art series lenses, the 15mm balances strong optical performance with handheld portability. At 240g, it i very compact and significantly lighter than the previous 16mm f/1.4 DC DN, making it easier to carry for street photography, travel, gimbal recording and for vlogging.
With a bright f/1.4 aperture, stepping motor autofocus and a compact mechanical design, this wide-angle lens suits beginners upgrading from kit zooms as well as intermediate creators looking for improved low-light performance and higher image quality.
Sigma 15mm f/1.4 DC Contemporary Lens for Canon RF 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 arrangement maintains good edge consistency and reduces aberrations that are often visible in wide-angle lenses.
On Canon APS-C cameras, the 15mm focal length provides an 83.6° angle of view, offering a broad field suitable for landscapes, architecture, interiors and environmental portraits.
Sigma has also looked at controlling sagittal coma flare, which is particularly relevant for night sky photography and scenes containing point light sources. Sharpness remains consistent across the frame, even 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 lenses. This supports lower ISO settings in dim conditions and provides greater flexibility when shooting indoors or at night.
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 increased 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 detail work.
Autofocus and Video Performance
Autofocus is driven by a stepping motor that moves a lightweight focus group with precision. This enables fast, accurate focusing for still photography while maintaining smooth transitions for video recording.
Focus breathing has been minimised to reduce visible changes in framing during focus adjustments. The compact build and wide angle of view also make it practical for gimbal-based shooting, cinematic video production and solo content creation, including webinars and live commerce setups.
The Canon RF Mount version features a control ring instead of an aperture ring, allowing customisable control functions through the camera body.
Construction and Design
The Canon RF version weighs 240g and uses a 58mm filter thread. Its compact dimensions improve 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 conditions.
