Sigma 30mm f/1.4 DC DN Contemporary Lens for Canon RF Mount Summary

The Sigma 30mm f/1.4 DC DN Contemporary Lens for Canon RF Mount is a standard prime lens, which combines exceptional image quality with an ultra-wide f/1.4 aperture and a lightweight design. Weighing approximately 285g, it stands out as one of the lightest f/1.4 lenses available for Canon’s APS-C mirrorless RF mount cameras, such as the EOS R7. This makes it an excellent choice for photographers and videographers who value a combination of performance and lightweight portability.

This newly released Sigma lens offers an equivalent full-frame focal length of 48mm, which is a popular standardlens, that’s ideal for a range of genres, from street photography and portraits to weddings, travel, and everyday shooting. Its fast autofocus also makes this particular mirrorless RF lens well-suited for video recording.

The wide f/1.4 aperture not only allows for a shallow depth of field to create beautifully blurred backgrounds but also helps to capture sharp, clear images in low-light conditions, which is especially useful when shooting handheld.

The Sigma 30mm f/1.4 lens for Canon RF Mount is part of a lineup of lightweight, crop-sensor primes featuring the same bright aperture, designed to deliver portability and high optical quality.

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.
