Sigma 18- vs VILTROX

Introduction to the Sigma 18-50mm and VILTROX 35mm

In this article, we will compare the Sigma 18-50mm F2.8 DC DN Contemporary lens with the VILTROX 35mm f1.7 E lens. Both lenses are designed for Sony E-mount cameras but cater to different photography needs. The Sigma lens is priced at $587.00, while the VILTROX lens is significantly cheaper at $179.00, making it about 69% less expensive. Understanding their features and capabilities can help photographers decide which lens suits their style better.

Price Comparison

When it comes to pricing, the VILTROX 35mm f1.7 E stands out as the more budget-friendly option at $179.00, compared to the Sigma 18-50mm, which retails for $587.00. This price difference of $408 signifies a substantial cost-saving for photographers who are looking for an effective lens without breaking the bank. While the Sigma lens offers a versatile zoom range, the VILTROX lens provides a bright aperture, making it an attractive option for those who prioritize low-light performance and background blur in their photography.

Optical Performance

Optical performance is a critical factor in choosing a lens. The Sigma 18-50mm boasts superb optical quality and features in-camera aberration correction, ensuring excellent image clarity and detail across its versatile 18-50mm focal range. In contrast, the VILTROX 35mm f1.7 E lens features an optimized optical design with 11 elements in 9 groups, including high refractive and aspherical elements. This design allows the VILTROX lens to minimize chromatic aberrations and distortion, providing sharp and vivid images ideal for a variety of photography styles.

Aperture and Low-Light Capability

The VILTROX 35mm f1.7 E lens shines when it comes to low-light performance due to its large maximum aperture of f/1.7. This feature allows photographers to capture stunning images in dimly lit environments and achieve beautiful background blur (bokeh). On the other hand, the Sigma 18-50mm has a constant aperture of f/2.8, which, while still good, does not perform as well in low-light situations compared to the VILTROX lens. For photographers who frequently shoot in challenging lighting, the VILTROX lens offers a distinct advantage.

Focal Length Versatility

The Sigma 18-50mm offers a versatile focal length range that makes it suitable for various photography genres, including landscapes, portraits, and street photography. Its zoom capability allows photographers to quickly adjust their framing without changing lenses. Conversely, the VILTROX 35mm lens has a fixed focal length of 35mm, which provides a natural perspective akin to the human eye. While it may not offer the same versatility as the Sigma, its specific focal length is perfect for portrait and street photography, making it a strong contender for those focused on these styles.

Autofocus Performance

When it comes to autofocus, both lenses have their strengths. The VILTROX 35mm f1.7 E is equipped with a new STM motor, which provides fast, precise, and near-silent autofocus performance, making it ideal for both stills and video recording. It also minimizes focus breathing, ensuring smooth transitions during video captures. The Sigma 18-50mm does not specifically mention its autofocus features, but its reputation suggests reliable performance. For users who prioritize fast and effective autofocus, especially in video scenarios, the VILTROX lens may be the better choice.

Build Quality and Design

In terms of design, the VILTROX 35mm f1.7 E is compact and lightweight, weighing only 170g, making it highly portable for photographers on the go. Its durable metal body ensures longevity and resilience against wear. The Sigma 18-50mm, while also designed for portability, may be slightly bulkier due to its zoom mechanism. However, it still maintains a relatively small and light profile for a zoom lens. Photographers who value a lightweight setup may find the VILTROX more appealing, especially for extended shooting sessions.

Which should you buy?

Choosing between the Sigma 18-50mm F2.8 DC DN Contemporary and the VILTROX 35mm f1.7 E largely depends on individual photography needs. If versatility and zoom functionality are paramount, the Sigma lens is the optimal choice despite its higher price. However, if you are looking for a budget-friendly option that excels in low-light situations and offers excellent portrait capabilities, the VILTROX lens is a fantastic investment. Ultimately, both lenses have unique strengths, making them suitable for different types of photographers.
