Both lenses cater to different photography needs, and understanding their features can help you make an informed decision. The Sigma lens is priced at $679.00, while the VILTROX lens is significantly cheaper at $179.00, making it about 74% less expensive.
Design and Build Quality
When it comes to design, the Sigma 10-18mm F2.8 DC DN is noted for being the world's smallest and lightest ultra-wide-angle zoom lens for APS-C cameras. This makes it particularly appealing for travel and landscape photography. In contrast, the VILTROX 35mm F1.7 is also lightweight, weighing only 170 grams. This compact design allows for easy handling and shooting in various environments. Although both lenses are lightweight, the Sigma lens offers the versatility of a zoom range, while the VILTROX provides a fixed focal length with a wider aperture.
Aperture Performance
The Sigma 10-18mm features a large aperture of F2.8 across its zoom range, allowing for expressive imaging capabilities, especially in low-light conditions. On the other hand, the VILTROX 35mm boasts a larger maximum aperture of F1.7, which is ideal for creating beautiful bokeh effects and achieving a dreamy blur that highlights subjects. While both lenses excel in aperture performance, the VILTROX provides a slight edge for portraiture and artistic photography due to its wider aperture.
Autofocus System
In terms of autofocus, the Sigma lens is designed for versatility, making it suitable for landscapes, travel, and video content creation. It does not specify advanced autofocus features. Conversely, the VILTROX 35mm F1.7 incorporates an efficient and reliable autofocus system powered by a built-in STM stepping motor. This allows for precise tracking and supports eye and face autofocus, enhancing the shooting experience for dynamic subjects. For photographers who prioritize autofocus technology, the VILTROX lens is a compelling option.
Optical Quality
The Sigma 10-18mm lens is engineered for expressive imaging, but specific optical details are not disclosed. The VILTROX, however, features an optical structure of 11 elements in 9 groups, including 1 ED lens and 1 aspherical lens. This optical arrangement, coupled with high-definition multi-layer coating, contributes to enhanced image clarity and reduced distortion. While both lenses promise quality, the detailed optical construction of the VILTROX suggests a well-thought-out design for sharp and vibrant images.
Versatility in Shooting
The Sigma 10-18mm is particularly versatile for various photography styles, including landscapes, travel, and video content creation, thanks to its wide zoom range. This makes it ideal for capturing expansive scenes and dynamic video footage. Conversely, the VILTROX 35mm is tailored more for portraiture and general photography, offering a focal length that is favored for its natural perspective. Depending on your shooting style, the Sigma lens may be more suitable for those who need versatility, while the VILTROX excels in more controlled, focused shooting scenarios.
Price Comparison
The Sigma 10-18mm F2.8 DC DN is priced at $679.00, whereas the VILTROX 35mm F1.7 is available for $179.00. This price difference of $500 highlights a significant disparity, with the VILTROX being about 74% cheaper. For budget-conscious photographers or those just starting, the VILTROX presents a strong value proposition without compromising on essential features like large aperture and autofocus capabilities.
User Experience
The Sigma lens is favored for its lightweight design and versatility, appealing to photographers who capture a wide range of subjects. It is well-suited for both video and photography, making it a reliable choice for content creators. The VILTROX lens, with its lightweight build and advanced autofocus, is ideal for spontaneous shooting, allowing users to capture moments effortlessly. While both lenses offer a great user experience, the choice ultimately hinges on the specific needs of the photographer.

Ultimately, your decision will hinge on whether you prioritize versatility or specialized features at a lower cost.
