Meanwhile, the VILTROX 25mm f1.7 weighs only 170 g, making it lightweight and easy to carry around, which is advantageous for spontaneous shooting. Both lenses boast compact designs, but Sigma's ultra-wide format offers broader applicability in various shooting scenarios, while VILTROX’s compactness is ideal for everyday carry.

Optical Performance

Optical performance is a key differentiator. The Sigma 10-18mm features a large aperture that enhances its capability to create expressive images, particularly in challenging lighting conditions.

Both lenses are compatible with a range of Sony E-mount cameras, including popular models like the A7C, A7RII, and A6400. This compatibility means that users can seamlessly integrate either lens into their existing kit. However, the Sigma 10-18mm is particularly suited for users looking to expand their wide-angle capabilities, while VILTROX is a great addition for those focused on portraiture and low-light shooting.
