Sigma 23mm f/1.4 DC DN Contemporary Lens for Canon RF Mount

Description

Sigma 23mm f/1.4 DC DN Contemporary Lens for Canon RF Mount Summary

With a 35mm equivalent full-frame focal length, the Sigma 23mm f/1.4 DC DN Contemporary Lens for Canon RF Mount is a slightly wide-angle prime lens designed for crop-format (APS-C) Canon mirrorless cameras.

Designed to be lightweight, sharp, and fast, it’s ideal for street photography, landscapes, environmental portraits, weddings, and documentary. It’s equally suited to video recording too, thanks to a near-silent autofocus mechanism and smooth 9-blade aperture design, which produces creamy bokeh and beautifully soft defocus areas in the image.

The wide f/1.4 aperture allows for faster shutter speeds, making it invaluable for handheld shooting, particularly in low-light conditions. It also provides a shallow depth of field, creating beautifully blurred backgrounds that enhance subject separation.

Despite its large aperture, the 23mm f/1.4 DC DN is impressively lightweight at just 345g, making this an excellent Canon RF mount lens for all-day shooting and as a convenient walk-around option. Its compact yet robust design, constructed with Sigma’s thermally stable composite (TSC) material, ensures both portability and durability.

Optically, this Sigma lens is designed to deliver crisp, accurate images, with sharp details across the frame at all aperture settings, rivalling even Sigma’s own Art-series lenses. It also pairs seamlessly with other DC DN primes, all featuring the same bright f/1.4 aperture, adding versatility and utility for a variety of creative situations.

Sigma 23mm 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

The optical design consists of 13 elements in 10 groups, including three SLD glass elements and two aspherical elements, ensuring sharp and clear image quality. The lens offers outstanding resolving power even at its maximum aperture, while the bright f/1.4 aperture creates stunning, smooth bokeh.

Its compact, palm-sized design enhances the shooting experience, allowing you to fully harness the capabilities of mirrorless cameras. Thoughtful measures to minimise flare and ghosting ensure clarity and contrast, even when shooting in backlit conditions.

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.

Flare and Ghosting Control

Sigma’s Super Multi-Layer Coating reduces 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.
