Introduction to the VILTROX 35mm f1.7 Fuji and YONGNUO YN50mm F1.8
The VILTROX 35mm f1.7 Fuji and YONGNUO YN50mm F1.8 are two popular camera lenses designed for different camera mounts. The VILTROX is tailored for Fujifilm X-Mount cameras, while the YONGNUO is compatible with Canon EF mount cameras. Both lenses offer unique features catering to various photography needs, but they also differ significantly in terms of price and specifications.
Pricing Comparison
When it comes to pricing, the VILTROX 35mm f1.7 Fuji retails for $179.00, while the YONGNUO YN50mm F1.8 is priced at $82.00. This makes the YONGNUO about 54% cheaper than the VILTROX. The lower price point of the YONGNUO could appeal to budget-conscious photographers, especially those who are just starting out or looking for a cost-effective lens for their Canon cameras. However, the VILTROX's higher price may reflect its advanced features and optical design.
Aperture and Low-Light Performance
Both lenses offer large maximum apertures, which enhance their performance in low-light conditions. The VILTROX boasts a bright f/1.7 aperture, allowing for exceptional low-light performance and beautiful background blur (bokeh), making it ideal for portraits and street photography. In contrast, the YONGNUO features a slightly smaller f/1.8 aperture, which still provides a good level of low-light capability but may not achieve the same level of bokeh as the VILTROX. The difference in aperture size may influence your choice depending on your photography style and lighting conditions.
Autofocus Systems
The VILTROX 35mm f1.7 Fuji is equipped with a new STM motor that delivers fast, precise, and near-silent autofocus performance. This feature is especially beneficial for video recording, as it minimizes focus breathing. On the other hand, the YONGNUO YN50mm F1.8 supports both auto focus and manual focus modes, offering flexibility for photographers who prefer manual control. However, it does not specify the same level of advanced autofocus technology as the VILTROX, which could affect the overall shooting experience.
Optical Design and Image Quality
In terms of optical quality, the VILTROX lens consists of 11 elements in 9 groups, including 2 High Refractive (HR) elements and 1 Extra-low Dispersion (ED) element. This optimized design reduces chromatic aberrations and flare, contributing to outstanding image quality. The YONGNUO, while offering a solid performance, has a simpler structure of 5 groups and 6 elements. The more complex optical design of the VILTROX may result in sharper images and better color accuracy, particularly in challenging lighting conditions.
Focal Length Versatility
The VILTROX has a 35mm focal length, which is ideal for capturing a natural perspective similar to the human eye. This makes it versatile for various photography styles, including landscapes and portraits. Conversely, the YONGNUO offers a 50mm focal length, which is often favored for portrait photography due to its ability to create flattering images with a pleasing perspective. Depending on your preferred shooting style, either lens could serve you well, but the choice between 35mm and 50mm may determine which is more suitable for your specific needs.
Minimum Focusing Distance
The minimum focusing distance is an important specification for close-up photography. The VILTROX 35mm f1.7 Fuji allows for a close focusing distance of just 0.33 meters (33cm), enabling stunning detail in macro shots. In comparison, the YONGNUO YN50mm F1.8 has a minimum focusing distance of 0.45 meters, which offers less flexibility for close-up photography. For photographers who enjoy capturing intricate details, the VILTROX provides a clear advantage in this regard.
Design and Build Quality
The VILTROX lens features thoughtful design details, including an extended lens hood that improves image contrast and protects against stray light. Additionally, it includes a USB-C upgrade port for firmware updates, enhancing its longevity and compatibility with future camera models. The YONGNUO, while well-built, lacks some of these advanced features, such as firmware upgrade capabilities. For users who prioritize durability and future-proofing their equipment, the VILTROX may be the better option.
Which should you buy?
Ultimately, the choice between the VILTROX 35mm f1.7 Fuji and the YONGNUO YN50mm F1.8 largely depends on your specific needs and budget. If you are a Fujifilm user seeking a high-quality lens with superior optical performance, fast autofocus, and advanced features, the VILTROX is worth the investment. However, if you are looking for a more budget-friendly option with solid performance for Canon cameras, the YONGNUO is a commendable choice. Consider your photography style, budget, and the type of subjects you plan to shoot to make the best decision for your needs.
