Price Comparison

The VILTROX 56mm f/1.7 E Lens for Sony is priced at $180.00, while the YONGNUO YN50mm 50mm f/1.8 Lens for Nikon is available for $102.00. This makes the YONGNUO about 43% cheaper than the VILTROX. If budget is a primary concern, the YONGNUO offers a significant savings opportunity, allowing photographers to allocate funds elsewhere or invest in other equipment. Despite the price difference, both lenses are designed to deliver quality performance in their respective categories, making them appealing options for different users.

Build Quality and Design

Both lenses feature compact designs, but the VILTROX weighs in at 170g, making it slightly lighter than the YONGNUO, which weighs about 203g. This difference of 33g may seem minor, but it can influence the comfort during extended shooting sessions. The VILTROX's lightweight nature may encourage users to carry it more frequently. However, the YONGNUO utilizes a high-precision metal bayonet and gold-plated contacts, which enhance durability. Therefore, while the VILTROX is more portable, the YONGNUO may provide a more robust build quality.

Optical Performance

The VILTROX lens features a focal length equivalent to approximately 85mm, along with a fast aperture of f/1.7, which is excellent for portrait photography. It includes 9 groups of 11 optical structures, including 4 ED lenses, ensuring minimized distortion and exceptional image quality. In contrast, the YONGNUO boasts a 50mm focal length with a maximum aperture of f/1.8, designed to create creamy background blur and capture stunning low-light images. Both lenses excel in optical performance, but the VILTROX may have an edge with its slightly wider aperture and advanced optical design.

Autofocus Capability

The VILTROX lens employs an STM silent motor that guarantees efficient and reliable autofocus. This feature allows even novice photographers to achieve precise focus quickly. On the other hand, the YONGNUO lens includes a face and eye recognition function that automatically adjusts focus and exposure. While both lenses provide autofocus capabilities, the VILTROX may be more suitable for those who prioritize fast and accurate focusing, particularly in dynamic shooting environments.

Versatility

The VILTROX lens is designed for Sony cameras, including models such as the a7IV, a7RV, and a6400, making it an excellent option for users within the Sony ecosystem. The YONGNUO, compatible with a wide range of Nikon F-Mount cameras, including the D3000 and D5000 series, provides versatility for Nikon users. The choice between the two largely depends on the user's camera system, as neither lens can be used interchangeably across brands.

Intended Use

The VILTROX is positioned as a portrait lens, with features that enhance character depth and background perspective. Its capabilities make it ideal for portrait photographers seeking to create a three-dimensional effect. Conversely, the YONGNUO lens is marketed as a standard prime lens suitable for various photography styles, including street photography and food blogging. If your primary focus is portrait photography, the VILTROX may be the better choice, while the YONGNUO offers broader usability for different photographic needs.
