Overview of the SIRUI 20mm T1.8 Anamorphic Lens

The SIRUI 20mm T1.8 Anamorphic Lens is priced at $599.00, presenting a higher investment compared to the Canon lens. This lens is optimized for APS-C or Super 35 sensors and offers a unique 1.33x squeeze factor, enabling a cinematic 2.35:1 widescreen ratio. This feature allows filmmakers to achieve a broader perspective without cropping, making it ideal for cinematic visuals and storytelling.

This lens is equipped with a precision STM stepping motor that ensures smooth and quiet autofocus, enhancing its usability for video creators. The T1.8 ultra-fast aperture allows for superior low-light performance, making it an excellent choice for capturing nighttime scenes or achieving a soft bokeh effect. The SIRUI lens weighs 480g, making it compact and suitable for handheld and gimbal shooting.

Image Quality Comparison

In terms of image quality, the Canon RF28mm F2.8 STM Lens excels with its three aspheric elements and Canon Super Spectra Coating. These features work together to minimize ghosting and flare, providing sharp and vibrant images suitable for both stills and video. The lens's ability to maintain clarity even at a wide aperture further enhances its overall quality.

On the other hand, the SIRUI 20mm T1.8 lens boasts its anamorphic design, which is specifically crafted for cinematic use. The 1.33x squeeze factor allows filmmakers to create expansive visuals that are otherwise difficult to achieve with standard lenses. While the Canon lens focuses on versatility for everyday photography, the SIRUI lens is tailored towards producing unique cinematic shots, making them suitable for different use cases.

Autofocus Performance

The autofocus performance of these lenses varies significantly. The Canon RF28mm F2.8 STM Lens features a leadscrew type STM focus drive, which is particularly suited for smooth and quiet video autofocus operations. This makes it an excellent choice for videography where noise reduction is crucial.

Conversely, the SIRUI 20mm T1.8 lens is equipped with a precision STM stepping motor that not only provides smooth and quiet autofocus but also includes advanced features like eye-tracking capabilities and an AF/MF switch. This level of control is particularly beneficial for filmmakers, as it allows for greater precision in capturing moving subjects, further elevating the lens's performance in dynamic shooting situations.

Use Cases

The Canon RF28mm F2.8 STM Lens is ideal for photographers who prioritize portability and everyday versatility. Its compact size and lightweight design make it perfect for street photography, travel, and casual videography. The lens's ability to function well on both full-frame and APS-C cameras expands its usability across various Canon EOS R series models.

In contrast, the SIRUI 20mm T1.8 lens is specifically aimed at filmmakers and video creators looking to achieve a cinematic look. With its anamorphic design and ultra-fast T1.8 aperture, it excels in low-light conditions and is excellent for capturing expansive landscapes or tight indoor spaces. The SIRUI lens is best suited for those who want to create professional-quality video content, making it a more specialized option compared to the Canon lens.

Price Comparison

The Canon RF28mm F2.8 STM Lens is priced at $299.00, making it about 50% cheaper than the SIRUI 20mm T1.8 lens, which retails for $599.00. This significant price difference is a crucial factor for many photographers and videographers. The affordability of the Canon lens makes it accessible to a broader audience, especially those just starting or on a budget.

While the SIRUI lens offers advanced features and a unique design that justifies its higher price, the Canon lens provides excellent value for those who need a reliable and versatile wide-angle option without breaking the bank. The decision between these two lenses may ultimately hinge on budget considerations and specific use-case requirements.

Portability and Build Quality

When it comes to portability, the Canon RF28mm F2.8 STM Lens stands out due to its pancake design, weighing significantly less than the SIRUI lens. Its lightweight nature makes it easy to carry around during long shooting sessions, making it an excellent companion for travel photography.

In contrast, the SIRUI 20mm T1.8 lens, while still compact at 480g, is bulkier compared to the Canon option. However, it is designed for durability and professional use, which may be more important for filmmakers who prioritize build quality over weight. The choice between the two may depend on whether the user values extreme portability or is willing to carry slightly more weight for enhanced performance and features.

Which should you buy?

Choosing between the Canon RF28mm F2.8 STM Lens and the SIRUI 20mm T1.8 Anamorphic Lens ultimately depends on your specific needs. If you are looking for a lightweight, versatile lens primarily for photography and casual videography, the Canon lens is an excellent choice, especially at its price of $299.00. However, if you are a filmmaker seeking to create cinematic visuals with advanced features and a unique anamorphic design, the SIRUI lens, despite its higher price of $599.00, offers capabilities that may well be worth the investment.
