The Sigma 17-40mm F1.8 DC is priced at $919.00, while the VILTROX 85mm F2.0 Z Lens is significantly cheaper at $275.00, making it about 70% less expensive. This stark price difference reflects the distinct purposes and features of each lens, catering to different types of photographers. The Sigma lens is a versatile zoom lens ideal for Sony E-mount APS-C cameras, whereas the VILTROX lens is a prime lens designed for Nikon full-frame cameras, particularly suited for portrait photography.
Design and Build Quality
The Sigma 17-40mm F1.8 DC features a robust design typical of Sigma's Art series, which is known for its professional build quality and aesthetic appeal. This lens is optimized for low-light conditions with its bright F1.8 aperture. In contrast, the VILTROX 85mm F2.0 Z Lens is compact and lightweight, weighing only 360g, which enhances its portability for on-the-go shooting. Both lenses are engineered for reliable performance, but the Sigma may appeal more to those who prioritize a premium feel, while the VILTROX offers a more ergonomic experience for extended handheld use.
Optical Performance
The Sigma 17-40mm F1.8 DC is designed to deliver sharp detail and professional image quality, particularly in low-light situations thanks to its constant aperture. The VILTROX 85mm F2.0 Z Lens, on the other hand, boasts a sophisticated optical design with 10 elements in 8 groups, including Extra-low Dispersion (ED) elements. This design minimizes chromatic aberration, resulting in crisp and vivid images. Both lenses aim for high optical quality, but the Sigma offers a broader focal range, which may be more versatile for various photography types, while the VILTROX excels in portraiture with its bokeh capabilities.
Autofocus Capabilities
The Sigma 17-40mm F1.8 DC is tailored for smooth autofocus performance, crucial for capturing fast-moving subjects or video content. However, specific autofocus speed details aren’t mentioned. In contrast, the VILTROX 85mm F2.0 Z Lens is equipped with a Stepping Motor (STM), which allows for smooth, quiet, and precise autofocus, making it ideal for both photography and video, particularly for portrait work. This difference highlights that while both lenses are capable, the VILTROX may be more advantageous for videographers and portrait photographers who require silent and accurate focusing.
Versatility in Usage
The Sigma 17-40mm F1.8 DC is a versatile zoom lens, making it suitable for a wide range of scenarios such as travel, landscapes, and video production. Its wide zoom range allows photographers to easily switch between different compositions without changing lenses. Conversely, the VILTROX 85mm F2.0 Z Lens is a prime lens that excels in portrait photography, providing a flattering compression and beautiful background blur. While the Sigma lens is ideal for those who need flexibility, the VILTROX is tailored specifically for portrait enthusiasts, offering a narrower focus but superior bokeh effects.
Low-Light Performance
The Sigma 17-40mm F1.8 DC stands out in low-light conditions with its bright F1.8 constant aperture, allowing photographers to shoot in dim environments without compromising image quality. This is particularly beneficial for indoor events or evening shoots. On the other hand, the VILTROX 85mm F2.0 Z Lens, with its F2.0 aperture, still performs well in low-light situations but may not match the Sigma’s capability. Thus, for those prioritizing low-light performance, the Sigma lens may be the preferable choice.
Price and Value Proposition
The Sigma 17-40mm F1.8 DC is priced at $919.00, reflecting its premium features and build quality. In contrast, the VILTROX 85mm F2.0 Z Lens is priced at $275.00, offering about 70% savings. While the Sigma lens may justify its higher price with its versatility and professional-grade optics, the VILTROX provides excellent value for portrait photographers who need a reliable lens without breaking the bank. For budget-conscious consumers, the VILTROX represents a compelling option without significant sacrifices in quality.
Which should you buy?
Choosing between the Sigma 17-40mm F1.8 DC and the VILTROX 85mm F2.0 Z Lens ultimately depends on your photography needs. If you are looking for a versatile zoom lens with exceptional low-light performance for a variety of shooting scenarios, the Sigma is worth the investment. However, if you specialize in portrait photography and seek a more affordable option with great bokeh and sharpness, the VILTROX is an excellent choice. Each lens has its strengths, so the decision should align with your specific photographic style and budget.
