The VILTROX 35mm f1.7 Fuji and YONGNUO YN50mm F1.8C Lens cater to different photography needs with distinct features and price points. The VILTROX lens is priced at $179.00, while the YONGNUO lens is available for $132.29, making the latter about 26% cheaper. Each lens has specific strengths that appeal to photographers depending on their camera systems and shooting preferences.
Design and Build Quality
The VILTROX 35mm f1.7 Fuji is designed specifically for Fujifilm X mount cameras, featuring a thoughtful design that includes an extended lens hood for improved image contrast and protection against stray light. It weighs in at a compact size, making it portable for various shooting conditions. On the other hand, the YONGNUO YN50mm F1.8C Lens, designed for Canon EF mount cameras, is also lightweight and compact, measuring just 2 inches in length. Both lenses are user-friendly and well-suited for amateur and professional photographers alike.
Optical Performance
In terms of optical quality, the VILTROX 35mm f1.7 Fuji stands out with its optimized optical design, comprising 11 elements in 9 groups, including special elements that minimize aberrations and distortions. This design helps to deliver sharp, vivid images across various photography styles. The YONGNUO YN50mm F1.8C, while also providing good optical performance, features 6 elements in 5 groups. While it offers a decent level of sharpness, it may not match the image quality provided by the VILTROX lens under challenging conditions.
Aperture and Low-Light Performance
The VILTROX 35mm f1.7 boasts a bright f/1.7 aperture that enhances low-light performance and creates beautiful background blur, making it ideal for portraits and street photography. This lens excels in situations where light is limited. Conversely, the YONGNUO YN50mm F1.8C features a f/1.8 aperture, which is also suitable for low-light conditions but slightly less effective than the f/1.7 aperture of the VILTROX. Both lenses are capable of producing pleasing bokeh, but the VILTROX may provide a slight advantage in depth-of-field control.
Autofocus Capabilities
The VILTROX 35mm f1.7 is equipped with a new STM motor that offers fast, precise, and near-silent autofocus performance. This feature is particularly beneficial for video recording, where focus transitions need to be smooth and unobtrusive. The YONGNUO YN50mm F1.8C also supports autofocus, but it may not be as swift or silent as the VILTROX lens. For photographers who prioritize fast and quiet focusing, the VILTROX is likely the better choice.
Versatility in Shooting Scenarios
The VILTROX 35mm f1.7 features a minimum focusing distance of just 0.33 meters, allowing photographers to capture stunning close-up shots with incredible detail. This versatility makes it suitable for a range of applications, from portraits to macro photography. In comparison, the YONGNUO YN50mm F1.8C has a magnification of 0.15, which is decent but does not offer the same close-focusing capabilities as the VILTROX lens. For users looking to explore various photography styles, the VILTROX lens provides greater flexibility.
Compatibility and Updates
The VILTROX 35mm f1.7 is compatible with a wide range of Fujifilm cameras, including popular models like the X-T1, X-T3, and X-PRO02. Additionally, it features a USB-C upgrade port that allows users to update the lens firmware, ensuring optimal performance and compatibility with new camera models. The YONGNUO YN50mm F1.8C is designed for Canon EOS cameras, offering compatibility with numerous models. However, it lacks the firmware update feature found in the VILTROX lens, which may limit its longevity regarding compatibility with future camera releases.
Which should you buy?
Deciding between the VILTROX 35mm f1.7 Fuji and the YONGNUO YN50mm F1.8C lens ultimately depends on your specific needs and camera system. If you own a Fujifilm camera and prioritize optical performance, low-light capabilities, and fast autofocus, the VILTROX is a worthwhile investment at $179.00. However, if you're looking for a more budget-friendly option for your Canon camera, the YONGNUO, priced at $132.29, offers solid performance for its price.
