VILTROXYONGNUO YN50mm F1.8 Lens Large Aperture Auto Focus

Overview of the VILTROX 35mm F1.7 and YONGNUO YN50mm F1.8

The VILTROX 35mm F1.7 is priced at $179.00, while the YONGNUO YN50mm F1.8 is significantly more affordable at $82.00, making it about 54% cheaper. This price difference may influence buyers looking for a budget-friendly option. Each lens caters to different camera systems — the VILTROX is designed for Sony E-Mount cameras, whereas the YONGNUO is compatible with Canon EF mount cameras.

Aperture and Optical Performance

Both lenses feature large apertures, allowing for creative photography and effective low-light performance. The VILTROX boasts an F1.7 aperture, providing a slight advantage over the YONGNUO's F1.8, which can create beautiful bokeh effects. The VILTROX achieves this with 9 aperture blades, enhancing the aesthetic quality of blurred backgrounds. On the other hand, the YONGNUO's aperture, while slightly larger, still supports a virtual background effect, making it enjoyable for photographers.

Autofocus Capabilities

The VILTROX lens is equipped with a built-in STM stepping motor, which allows for efficient and reliable autofocus, including support for eye and face detection. This advanced autofocus system enhances tracking focus with reduced latency and vibration. In contrast, the YONGNUO supports both auto and manual focus modes, providing versatility for different shooting styles, but lacks the advanced features found in the VILTROX. This difference may be critical for users who prioritize fast and precise autofocus in dynamic shooting situations.

Construction and Design

The VILTROX 35mm F1.7 is designed with an optical structure comprising 11 elements in 9 groups, including specialized lenses for improved image quality. Its lightweight design at 170 g makes it portable and suitable for spontaneous shooting. Conversely, the YONGNUO features a 5 groups 6 slices lens structure, which is adequate but not as complex as the VILTROX. The use of multi-coated lenses in the YONGNUO helps improve transmittance, but overall, the VILTROX's advanced optical design may yield sharper images.

Portability and Usability

Portability is a strong point for the VILTROX due to its compact and lightweight nature, allowing photographers to carry it easily on the go. This makes it an excellent choice for street photography or travel. While the YONGNUO is also manageable, its slightly heavier design may not appeal as much to those prioritizing portability. The VILTROX also includes a micro USB interface for firmware upgrades, ensuring that users can keep their lens updated with the latest performance enhancements.

Price Comparison

The VILTROX 35mm F1.7 is priced at $179.00, whereas the YONGNUO YN50mm F1.8 is available for $82.00. This substantial price gap of $97.00 may deter budget-conscious photographers from opting for the VILTROX unless they require specific features it offers. The YONGNUO's affordability allows it to cater to beginners or those looking for a cost-effective solution without sacrificing essential functionalities.

Compatibility with Camera Systems

Compatibility is a crucial factor when choosing between these two lenses. The VILTROX is specifically designed for Sony E-Mount cameras, making it an excellent option for users of models like the FX3, A7C, and A6400. In contrast, the YONGNUO is compatible with Canon EF mount cameras, making it suitable for a different audience. This distinction means that potential buyers must consider their existing camera systems when deciding which lens to purchase.

Which should you buy?

Ultimately, the decision between the VILTROX 35mm F1.7 and the YONGNUO YN50mm F1.8 hinges on your specific needs and budget. If you are a Sony user looking for advanced autofocus capabilities and superior optical performance, the VILTROX may be worth the investment at $179. However, if you are a Canon user or a beginner seeking a budget-friendly option that still offers quality features, the YONGNUO at $82 is an excellent choice.
