The SIRUI lens is priced at $599.00, while the Sony lens costs $698.00, making the SIRUI about 14% cheaper. Each lens offers unique features tailored to different shooting styles and scenarios.
Design and Build Quality
In terms of design, the SIRUI 20mm T1.8 boasts a compact and lightweight build, weighing only 480g (1.06 lbs). This makes it an ideal choice for handheld and run-and-gun shooting. On the other hand, the Sony E 11mm F1.8 is also designed to be compact and lightweight, making it a great match for APS-C and Super35 E-mount cameras. Both lenses are built for durability and ease of handling, but the SIRUI's specific design elements for film production, such as its focus mechanism, may appeal more to videographers.
Aperture and Low-Light Performance
The SIRUI 20mm T1.8 offers an ultra-fast T1.8 aperture, allowing more light to enter for enhanced low-light performance and improved bokeh. This feature is particularly beneficial for capturing night scenes and achieving a shallow depth of field. Conversely, the Sony E 11mm F1.8 also features a large F1.8 aperture, supporting dynamic backgrounds and beautiful bokeh. While both lenses excel in low-light conditions, the SIRUI's T1.8 rating gives it a slight edge in terms of light-gathering capabilities.
Autofocus Features
The SIRUI 20mm T1.8 is equipped with a precision STM stepping motor, providing smooth and quiet autofocus with eye-tracking capabilities. This feature, along with an AF/MF switch and autofocus lock, caters to filmmakers who need precision and control during shoots. The Sony E 11mm F1.8 features two linear motors that deliver fast and precise autofocus, which is essential for capturing both stills and video content smoothly. While both lenses excel in autofocus, the SIRUI's additional features may be more appealing for dedicated video creators.
Field of View and Versatility
The SIRUI 20mm T1.8 offers a horizontal field of view equivalent to a 22mm full-frame lens, making it well-suited for various shooting scenarios, including landscapes and indoor spaces. The Sony E 11mm F1.8, with an 11mm field of view, excels in ultra-wide-angle photography, making it ideal for vlogging and capturing expansive scenes. While the SIRUI lens is more versatile for different types of shots, the Sony lens is specifically designed for ultra-wide perspectives, which can be advantageous for certain creatives.
Image Quality and Clarity
Both the SIRUI 20mm T1.8 and Sony E 11mm F1.8 are designed to deliver outstanding image quality. The SIRUI lens features a 37mm image circle optimized for Super 35 sensors, ensuring excellent coverage and clarity. The Sony lens is also engineered for remarkable sharpness and naturally rendered images. While both lenses promise high-quality results, the SIRUI's focus on cinematic visuals may make it the preferred choice for filmmakers.
Price Comparison
The SIRUI 20mm T1.8 is currently priced at $599.00, making it a more budget-friendly option compared to the Sony E 11mm F1.8, which is priced at $698.00. This price difference of about $99 indicates that the SIRUI lens offers excellent value for its feature set, particularly for those focused on video production. While the Sony lens also provides strong capabilities, the SIRUI might appeal more to those looking to maximize their investment without sacrificing quality.
Which should you buy?
Ultimately, the choice between the SIRUI 20mm T1.8 and Sony E 11mm F1.8 depends on your specific needs as a creator. If you prioritize a cinematic look, precise autofocus control, and a slightly lower price point, the SIRUI lens is a fantastic option. However, if you require an ultra-wide-angle lens for vlogging or capturing expansive scenes, the Sony lens offers excellent performance and versatility. Consider your shooting style and intended use to make the best decision for your photography or videography needs.
