SIRUI vs Viltrox

Overview of the Products

The SIRUI 20mm T1.8 1.33X Anamorphic Lens is designed for a cinematic experience, while the Viltrox 35mm F1.7 E lens focuses on versatility and portability. Priced at $599.00, the SIRUI lens aims to deliver high-quality cinematic visuals, whereas the Viltrox lens is more budget-friendly at $179.00, making it about 70% cheaper than the SIRUI option. This significant price difference indicates that each lens caters to different audiences and needs in photography and videography.

Intended Use and Target Audience

The SIRUI 20mm T1.8 lens is tailored for cinematographers and video creators seeking an immersive 2.35:1 widescreen ratio through its 1.33x squeeze factor. This lens is perfect for capturing expansive landscapes and dynamic scenes, making it ideal for film production. On the other hand, the Viltrox 35mm F1.7 E lens is designed for photographers who value versatility, excelling in portrait, landscape, and street photography. Its prime portrait-length focal length makes it a fantastic choice for everyday shooting, reflecting its suitability for both budding and experienced photographers.

Aperture and Light Performance

The SIRUI lens boasts an ultra-fast T1.8 aperture, allowing more light to enter, which is beneficial for low-light conditions and achieving a shallow depth of field. This feature is crucial for filmmakers who want to create soft bokeh and enhance the clarity of their subject in challenging lighting. Conversely, the Viltrox lens offers a bright f/1.7 maximum aperture, which also supports low-light performance but lacks the cinematic flair of the SIRUI's anamorphic capabilities. While both lenses perform well in low light, the SIRUI lens provides a more specialized solution for cinematic projects.

Autofocus Capabilities

The SIRUI 20mm T1.8 lens features selectable manual and autofocus, enhanced by a precision STM stepping motor. This setup ensures smooth, quiet focus transitions, which is essential for video production. Additionally, its eye-tracking capabilities allow for more accurate focusing on moving subjects. In contrast, the Viltrox 35mm F1.7 E lens also supports autofocus, designed for near-silent operation, making it suitable for candid shots. However, it does not provide the same level of advanced tracking features as the SIRUI lens, indicating that while both lenses offer autofocus, the SIRUI is tailored for more complex shooting scenarios.

Build and Weight

The SIRUI 20mm T1.8 lens weighs about 480 grams, which, while slightly heavier, is still manageable for filmmakers using handheld setups or gimbals. Its compact design allows it to maintain high visual quality without being overly cumbersome. The Viltrox 35mm F1.7 E lens, on the other hand, is significantly lighter at only 170 grams, making it an excellent choice for travel and everyday use. This substantial difference in weight makes the Viltrox more appealing for those who prioritize portability without sacrificing performance.

Image Circle and Coverage

The SIRUI lens features a 37mm image circle, optimized for APS-C or Super 35 sensors, which is crucial for delivering excellent coverage and image clarity in video production. This capability is particularly advantageous for filmmakers aiming for high-quality visuals. In contrast, the Viltrox lens is similarly designed for APS-C-format E-mount cameras, providing a 35mm equivalent focal length. While both lenses cater to similar sensor formats, the SIRUI’s optimized coverage may give it an edge in delivering cinematic quality.

Price Comparison

With a price tag of $599.00 for the SIRUI lens and $179.00 for the Viltrox lens, the SIRUI is about 70% more expensive. This price difference reflects the specialized features and quality of the SIRUI lens, aimed at serious filmmakers, while the Viltrox lens offers a more accessible option for casual photographers and those on a budget. The lower price of the Viltrox does not compromise its performance, making it an excellent value for users who need a reliable, versatile lens without breaking the bank.

Which should you buy?

Choosing between the SIRUI 20mm T1.8 1.33X Anamorphic Lens and the Viltrox 35mm F1.7 E lens ultimately depends on your specific needs. If you are a filmmaker looking for advanced features such as an ultra-fast aperture and a cinematic experience, the SIRUI lens is worth the higher investment. However, if you are a photographer seeking versatility, lightweight design, and affordability for everyday use, the Viltrox lens is an excellent choice. Each lens excels in its respective category, making the decision largely dependent on whether you prioritize cinematic capabilities or general photographic versatility.
