Dimension comparison
Overview of the VILTROX 35mm f1.7 E and YONGNUO YN50mm F1.8
The VILTROX 35mm f1.7 E is priced at $179.00, while the YONGNUO YN50mm F1.8 comes in significantly cheaper at $82.00, making it about 54% less expensive. This price difference is a crucial factor for budget-conscious photographers. Both lenses offer distinct advantages, appealing to different types of photography and camera systems.
Target Audience and Compatibility
The VILTROX 35mm f1.7 E is designed for Sony E-mount cameras, making it an excellent choice for users of models like the ZV-E10 II and a6600. In contrast, the YONGNUO YN50mm F1.8 is compatible with Canon EF mount cameras, catering to EOS camera users. Therefore, the choice between these lenses largely depends on the camera system you own, as neither lens can be used with the other's mount.
Aperture and Low-Light Performance
The VILTROX 35mm f1.7 E features a f/1.7 maximum aperture, providing excellent low-light performance and beautiful bokeh. This is particularly beneficial for portrait and street photography, where capturing detail in challenging lighting conditions is essential. Meanwhile, the YONGNUO YN50mm F1.8, with its f/1.8 aperture, also offers good low-light capabilities but may not achieve the same level of background blur as the VILTROX. The slight difference in aperture size may influence photographers who prioritize low-light performance and aesthetic blur.
Autofocus Capabilities
The VILTROX 35mm f1.7 E boasts fast, precise, and near-silent autofocus, thanks to its STM motor. This feature is advantageous for both still photography and video recording, as it minimizes focus breathing during transitions. On the other hand, the YONGNUO YN50mm F1.8 supports both auto and manual focus modes, offering versatility but may not match the speed of the VILTROX in fast-paced shooting scenarios. For users prioritizing quick autofocus, the VILTROX may be the preferable option.
Build Quality and Design
The VILTROX 35mm f1.7 E is built with a sleek and durable metal body, weighing only 170g, making it highly portable for on-the-go photographers. It also includes thoughtful design details like an extended lens hood and a USB-C upgrade port for firmware updates. In contrast, the YONGNUO YN50mm F1.8, while functional, does not emphasize build quality to the same extent and lacks advanced features like firmware updates. For those who prioritize durability and modern design, the VILTROX stands out.
Optical Performance
The VILTROX 35mm f1.7 E features an optimized optical design with 11 elements in 9 groups, including high refractive and extra-low dispersion elements, which help minimize chromatic aberrations and distortion. This level of optical engineering ensures exceptional image quality across various photography styles. While the YONGNUO YN50mm F1.8 has a simpler lens structure, it is still capable of delivering decent image quality for its price. However, serious photographers may prefer the superior optical performance of the VILTROX.
Price and Value Proposition
With a current price of $179.00, the VILTROX 35mm f1.7 E is a more significant investment compared to the YONGNUO YN50mm F1.8, priced at $82.00. This makes the YONGNUO about 54% cheaper, appealing to beginner photographers or those on a tighter budget. However, the VILTROX offers advanced features, superior optics, and build quality that may justify its higher cost for more serious enthusiasts or professionals. Ultimately, the choice hinges on how much value you place on performance versus budget.
Which should you buy?
Choosing between the VILTROX 35mm f1.7 E and YONGNUO YN50mm F1.8 largely depends on your camera system, budget, and photography needs. If you own a Sony E-mount camera and are looking for superior optical performance, fast autofocus, and a robust build, the VILTROX 35mm f1.7 E is worth the investment. However, if you are using a Canon EF mount camera and need a more budget-friendly option for casual photography, the YONGNUO YN50mm F1.8 serves as a solid choice. Consider your preferences and requirements carefully before making a decision.
