Price Comparison

The Canon RF100mm F2.8 L Macro is USM Lens is priced at $1,248.95, while the SIRUI 20mm T1.8 Anamorphic Lens retails for $599.00. This makes the SIRUI lens about 52% cheaper than the Canon lens. When considering budget constraints, the significant price difference may sway buyers towards the SIRUI for those who prioritize cost-effectiveness over specific features. However, the higher price of the Canon lens reflects its advanced macro capabilities and brand reputation in the photography community.

Lens Type and Purpose

The Canon RF100mm F2.8 L Macro is primarily a medium telephoto macro lens designed for detailed close-up photography, delivering a maximum magnification of 1.4x. It excels in portrait and macro shots, making it an excellent choice for photographers focused on capturing intricate details. In contrast, the SIRUI 20mm T1.8 is an anamorphic lens that caters to videographers and filmmakers, providing a cinematic 2.35:1 widescreen ratio. This differentiation in lens type underscores the diverging needs of users in photography versus videography, with each lens serving distinct purposes.

Image Stabilization Features

The Canon RF100mm F2.8 boasts an Optical Image Stabilizer that offers up to 5 stops of shake correction. This feature is particularly beneficial for macro photography, where even the slightest movement can lead to blurry images. Additionally, the Canon lens includes a Hybrid IS system that compensates for angular and shift camera shake, essential for achieving stable close-up shots. On the other hand, the SIRUI 20mm T1.8 does not explicitly mention image stabilization features. While it provides excellent autofocus capabilities, the lack of stabilization may impact handheld shooting in dynamic environments, making the Canon lens more reliable for those requiring stability.

Autofocus Capabilities

The autofocus system of the Canon RF100mm F2.8 is noted for its fast and precise performance, optimized for macro photography. With its advanced autofocus features, this lens allows photographers to capture intricate details effortlessly. In contrast, the SIRUI 20mm T1.8 features a precision STM stepping motor that delivers smooth and quiet autofocus, specifically designed for video. Its eye-tracking capabilities and manual focus options give filmmakers creative control, but the Canon lens’s macro-focused autofocus can significantly enhance the quality of still images, making it superior for those who prioritize photography.

Aperture and Low-Light Performance

The Canon RF100mm F2.8 has a bright fixed f/2.8 aperture, which is beneficial for low-light conditions and achieving beautiful background blur in portraits. This aperture allows for greater versatility when shooting in various lighting scenarios. In comparison, the SIRUI 20mm T1.8 offers an ultra-fast T1.8 aperture, enabling it to perform well in low-light conditions as well. While both lenses provide excellent low-light capabilities, the Canon lens’s macro-specific f/2.8 aperture may yield better results for photographers focused on depth of field in close-up shots, while the SIRUI lens may appeal more to those interested in wide-angle cinematics.

Build Quality and Portability

The Canon RF100mm F2.8 is designed with professional-grade build quality suited for full-frame EOS R series cameras. It incorporates features that enhance durability, making it reliable for extensive use in various environments. Conversely, the SIRUI 20mm T1.8 is compact and lightweight, weighing only 480g (1.06lb). This portability makes it an attractive choice for filmmakers and content creators who require a lens that is easy to carry during long shoots. While the Canon lens may offer superior durability, the SIRUI lens excels in mobility, catering to those who prioritize ease of use and transport.

Creative Control Features

The Canon RF100mm F2.8 includes a Spherical Aberration (SA) Control Ring, allowing users to adjust the shape and character of the foreground and background bokeh. This feature provides photographers with creative control over their images, enabling unique artistic expressions. On the other hand, the SIRUI 20mm T1.8 also emphasizes creative control through its selectable manual and autofocus options, including an AF/MF switch and autofocus lock. While both lenses offer features that enhance creativity, the unique bokeh control of the Canon lens may provide photographers with more nuanced artistic possibilities.

Which should you buy?

Choosing between the Canon RF100mm F2.8 L Macro is USM Lens and the SIRUI 20mm T1.8 Anamorphic Lens largely depends on your intended use. If your focus is on macro photography and you require superior image stabilization, fast autofocus, and creative control over bokeh, the Canon lens is the clear winner despite its higher price. However, for videographers seeking a cinematic experience at a more affordable price point, the SIRUI lens offers excellent features, including a lightweight design and versatile autofocus capabilities. Ultimately, your choice should align with whether you prioritize macro photography or video capabilities.
