Sigma 30mm f/1.4 DC DN Contemporary Lens for Canon RF Mount in More Detail
Developed for Canon RF mount
A specialised control algorithm has been developed, which optimises AF drive and communication speed specifically for Canon RF mount interchangeable cameras. This enables high-speed autofocus while also supporting Servo AF and in-camera aberration correction with supported bodies.
The lens mount also features rubber sealing, ensuring reliable performance across a range of shooting environments including during inclement conditions.
Advanced Technology in a Compact Design
The compact lens prioritises outstanding image quality and incorporates Sigma’s latest technologies, including digital correction for optical distortion. It is optimised for lightweight, compact camera bodies with a short flange distance, balancing portability with exceptional performance. Its specially designed focus lens group ensures fast, smooth autofocus, making it well suited for both video and stills.

Lightweight Build with Exceptional Optics
Through the use of high-refractive index, high-dispersion glass, this lens is designed with a shorter length without compromising on optical performance. Two aspherical elements enhance image quality while maintaining its compact size, which is ideal for smaller mirrorless cameras.
Additionally, inner focusing technology and lighter lens elements allow for a smaller, more efficient actuator, for excellent stability and ease of use, even when handholding.
Durable and Stable Composite Construction
Made from Thermally Stable Composite (TSC), the lens barrel and aperture components are built for precision and durability. TSC’s elasticity minimises deformation and reduces gaps between parts over time, enhancing the longevity and performance of the lens. This material ensures smooth aperture operation and supports the compact design, while also improving the precision of the internal mechanisms that house the focus lens group.
Professional-Level Image Quality
Designed to rival Sigma’s own prestigious Art line lenses, the 30mm f/1.4 features an optimised optical layout with elements to minimise transverse chromatic aberration and deliver exceptional sharpness across the frame. Leveraging in-body correction on compatible cameras, the lens enhances distortion control and sharpness.

Flare and Ghosting Control
Sigma’s Super Multi-Layer Coatingreduces flare and ghosting which is often caused by strong light sources, such as backlit scenes. The lens hood provides additional protection from extraneous light, maintaining consistent image quality with high contrast and good levels of sharpness irrespective of lighting conditions.
Beautiful Bokeh with Wide f/1.4 Aperture
The wide f/1.4 aperture allows for shallow depth of field, while producing stunning bokeh effects for creative photography. Its 9-blade rounded diaphragm ensures smooth, attractive background blur, and helps to separate the subject from distracting backgrounds.

Quiet, Accurate Autofocus for Video
Sigma’s stepping motor technology (STM) ensures smooth, silent autofocus, which is perfect for video recording. The lens is compatible with AF technologies, helping users capture more consistent focus, even on moving subjects.
Robust Brass Mount for Durability
The lens features a rugged brass mount, which combines high precision with strength. Treated surfaces and reinforced construction contribute to its reliability, ensuring it can withstand the rigours of use for extended periods.

Enhanced Lens Hood Design
The included lens hood is extra-long with an anti-reflective coating to control stray light effectively. Its rubber and textured anti-slip design improves grip, offering additional stability while shooting.
