Priced at $179.00, the VILTROX lens provides an attractive option for budget-conscious photographers. In contrast, the SIGMA lens comes in at $599.99, making it about 234% more expensive than the VILTROX lens. This price difference can influence purchasing decisions, especially for those who are just starting out or looking for a reliable lens without a hefty investment.

Build Quality and Design

Both lenses are designed with portability and ease of use in mind. The SIGMA 18-50mm boasts a lightweight and compact design, weighing just 300g, making it the smallest in its class with a maximum diameter of 69.2mm and a length of 74.5mm. The rubber-sealed mount adds a level of durability for use in various environments. On the other hand, the VILTROX 35mm is even lighter at 170g, which enhances its portability for spontaneous shooting. This lightweight design, combined with a compact build, makes the VILTROX a favorite for photographers on the go.

Aperture and Image Quality

When it comes to aperture, the VILTROX 35mm F1.7 has a larger maximum aperture of F1.7 compared to SIGMA's F2.8. This means the VILTROX lens can create a more pronounced bokeh effect and better low-light performance. With 9 aperture blades, it produces a beautiful blur that highlights the subject effectively. Conversely, the SIGMA lens delivers high performance as a versatile zoom lens, allowing for a range of focal lengths from 18mm to 50mm. While the VILTROX excels in creating artistic effects, the SIGMA is designed for more general photography needs.

Autofocus Performance

The VILTROX 35mm lens features efficient and reliable autofocus thanks to its built-in STM stepping motor, which supports eye and face autofocus. This ensures precise tracking and reduces latency, making it suitable for fast-paced shooting scenarios. In contrast, the SIGMA 18-50mm's autofocus capabilities are not explicitly detailed but are designed to complement the Canon RF mount system, promising high performance and quality. However, the specific advantages of the VILTROX's autofocus system may appeal more to those focused on portrait and action photography.

Minimum Focusing Distance

The minimum focusing distance is an important factor for photographers who want to capture close-up shots. The SIGMA 18-50mm has a minimum focusing distance of 12.1cm, allowing for a maximum magnification of 1:2.8. This capability enables photographers to take advantage of its zoom functionality for detailed close-ups. In comparison, the VILTROX 35mm does not specify its minimum focusing distance, which may limit its versatility for macro photography. For those who prioritize close-up capabilities, the SIGMA lens holds a distinct advantage.

Versatility and Use Cases

The SIGMA 18-50mm lens is highly versatile, making it suitable for a wide range of photography styles, from landscapes to portraits. Its zoom range allows for quick adjustments without needing to change the lens, which is particularly beneficial in dynamic shooting scenarios. The VILTROX 35mm, while offering a fantastic aperture for artistic shots, is more specialized. It is ideal for portraiture and low-light scenarios but may not provide the same flexibility in various shooting conditions. Photographers must consider their specific needs when choosing between these two lenses.

Compatibility

Compatibility is a vital consideration when selecting a lens. The SIGMA 18-50mm is specifically designed for Canon RF mount mirrorless cameras, making it a perfect match for users of that system. On the other hand, the VILTROX 35mm is compatible with a wide range of Sony E-mount cameras, including popular models like the FX3, A7C, A7RII, and A9. This broad compatibility may attract Sony users looking for high-quality prime lenses. Therefore, the choice of lens may ultimately depend on the camera system you own.

Which should you buy?

In conclusion, the decision between the SIGMA 18-50mm F2.8 and the VILTROX 35mm F1.7 largely depends on your specific needs and budget. The VILTROX offers a more affordable option with its impressive aperture and lightweight design, making it suitable for those focused on portraits and low-light photography. Conversely, the SIGMA lens provides versatility and a compact design, making it ideal for a broader range of photography styles. Consider your shooting preferences, camera compatibility, and budget when making your choice.
