SIRUI vs VILTROX

Overview of the SIRUI 20mm T1.8 and VILTROX 35mm F1.7

The SIRUI 20mm T1.8 Anamorphic Lens is priced at $599.00, while the VILTROX 35mm F1.7 comes in at $179.00, making it about 70% more affordable than the SIRUI lens. Both lenses cater to E-Mount cameras, but they serve different purposes and offer distinct features tailored to varying shooting needs.

Intended Use and Target Audience

The SIRUI 20mm T1.8 is designed primarily for cinematographers and video creators who seek to create cinematic visuals with a 1.33x squeeze factor for a wider aspect ratio. In contrast, the VILTROX 35mm F1.7 is geared towards photographers looking for a versatile prime lens with a large aperture for beautiful bokeh effects. This distinction means that while the SIRUI is ideal for video work, the VILTROX is better suited for general photography.

Autofocus Capabilities

Both lenses utilize advanced autofocus systems, but the SIRUI offers selectable manual and autofocus features powered by a precision STM stepping motor, ensuring smooth and quiet operation. It also includes eye-tracking capabilities, making it particularly advantageous for video creators who require fast and accurate focusing. The VILTROX, while also featuring an STM motor, emphasizes reliable autofocus for photography, including support for eye and face detection, enhancing its usability for portrait photography.

Aperture and Low-Light Performance

The SIRUI 20mm features an ultra-fast T1.8 aperture, allowing for excellent low-light performance and depth of field control. This is crucial for filmmakers who need to shoot in various lighting conditions. The VILTROX 35mm, with its F1.7 aperture, also excels in low-light environments but offers a slightly narrower light entry compared to the SIRUI. Both lenses produce captivating bokeh, but the SIRUI’s wider aperture provides an edge for more dramatic effects in cinematic applications.

Build Quality and Portability

Weighing in at 480g, the SIRUI lens is compact yet robust, making it suitable for handheld and gimbal shooting. Its design prioritizes portability without compromising on optical quality. The VILTROX, at just 170g, is even lighter, which can be a significant advantage for spontaneous shooting situations. This lightweight design allows photographers to carry it effortlessly, making it a favorite for street photography and travel.

Optical Performance

The SIRUI 20mm is optimized for Super 35 sensors, providing excellent coverage and image clarity that filmmakers demand. It is designed to deliver a stunning cinematic view and expansive landscapes without cropping. The VILTROX, with its optical structure of 11 elements in 9 groups, including ED and aspherical lenses, ensures high-definition images with minimal distortion. This makes it a reliable choice for photographers who desire sharp and clear images.

Price Comparison

The SIRUI 20mm T1.8 is priced at $599.00, while the VILTROX 35mm F1.7 is significantly less at $179.00. This makes the VILTROX about 70% cheaper than the SIRUI lens. For those on a budget or looking for a reliable lens for everyday use, the VILTROX offers a compelling value proposition without sacrificing essential features. The price difference is substantial, indicating that the choice between them will heavily depend on the user's specific needs and budget.

Which should you buy?

Your choice between the SIRUI 20mm T1.8 and the VILTROX 35mm F1.7 will largely depend on your intended use. If you are a filmmaker seeking to create cinematic visuals with high-quality anamorphic effects, the SIRUI is the clear winner despite its higher price. However, if you are a photographer looking for a versatile, lightweight option for everyday shooting, the VILTROX offers excellent value at a significantly lower price. Ultimately, both lenses excel in their niches, making your specific requirements the determining factor in your decision.
