Optical Performance

Build Quality

When it comes to build quality, the Sigma 28-70mm F2.8 DG DN is noted for its superb construction, which is a hallmark of Sigma's Contemporary line. It features a lightweight and compact design, making it easy to carry for daily use. On the other hand, the Canon RF24-105mm lens is also compact and lightweight, designed for convenience without sacrificing quality. Both lenses prioritize portability, but the Sigma's focus mode switch and nano porous coating give it an edge in durability and usability.

Autofocus and Stabilization

The Canon RF24-105mm features optical image stabilization with up to 5 stops of shake correction, which is beneficial for handheld shooting and video recording. Its leadscrew-type STM motor enables smooth autofocusing, ensuring crisp images even in dynamic scenarios. The Sigma lens, while it does not explicitly mention stabilization, offers internal focusing and a reliable autofocus system that is known for speed and accuracy. For users who prioritize stabilization, the Canon lens may be more suitable.

Versatility and Use Cases

The Canon RF24-105mm lens is incredibly versatile, making it suitable for various photography styles, including landscapes, travel, and portraiture. Its ability to focus on subjects as close as 0.43 ft with macro capabilities makes it a favorite among those who enjoy detailed photography. Meanwhile, the Sigma 28-70mm, while also versatile, is primarily geared towards those who favor a standard zoom lens that excels in low-light conditions. The larger aperture allows for more creative control over depth of field, making it a strong choice for portrait photographers.

User Experience and Control

The Canon RF24-105mm offers a control ring for quick adjustments to settings such as shutter speed and aperture, enhancing the user experience for those who prefer manual control. This feature can be particularly useful in fast-paced shooting environments. The Sigma lens also emphasizes user comfort with its focus mode switch, allowing photographers to quickly change between auto and manual focus. Both lenses focus on providing a seamless user experience, but the Canon's added control ring may appeal more to those wanting instant adjustments.

Brand and Reputation

Canon and Sigma both have strong reputations in the photography industry. Canon is renowned for its extensive range of high-quality lenses and cameras, while Sigma is celebrated for its innovative designs and optical performance. The Canon RF24-105mm lens is part of the RF series, which is designed for Canon’s mirrorless cameras, making it a reliable choice for Canon users. Meanwhile, the Sigma 28-70mm is specifically designed for Sony E-mount cameras, targeting a different user base.

Which should you buy?
