Dimension comparison
Overview
In the realm of camera lenses, the VILTROX 56mm f/1.7 E Lens for Sony and the YONGNUO YN50mm F1.8C Lens for Canon present two distinct choices for photographers. The VILTROX lens comes with a price tag of $180.00, while the YONGNUO is significantly cheaper at $132.29, making it about 26% less expensive. However, price isn't the only factor to consider when choosing between these two lenses.
Focal Length and Aperture
The VILTROX features a focal length of 56mm with a maximum aperture of f/1.7, providing a full-frame equivalent of approximately 85mm, ideal for portrait photography. In contrast, the YONGNUO has a 50mm focal length and also boasts a fast maximum aperture of f/1.8. The slight difference in focal length and aperture can affect how each lens performs in low-light situations and its ability to achieve a shallow depth of field. The VILTROX may offer a slight edge for portrait work due to its wider aperture, delivering a more pronounced background blur.
Autofocus Performance
Both lenses are designed with autofocus capabilities, but they utilize different technologies. The VILTROX employs a STM silent motor for efficient and reliable autofocus, promising a quick and precise experience for users, including beginners. The YONGNUO also supports both autofocus and manual focus but does not specify the technology used for its autofocus system. Given that the VILTROX emphasizes its advanced autofocus, it may be the better option for those prioritizing speed and accuracy in their shooting.
Weight and Portability
When it comes to weight, the VILTROX is notably compact at just 170 grams. This lightweight design makes it convenient for photographers who are always on the go. The YONGNUO, while also portable at 2 inches in length, does not specify its weight. However, the compactness of the VILTROX can be a decisive factor for travel photographers looking to minimize their gear load without sacrificing quality.
Build Quality and Optical Features
The optical construction of each lens differs significantly, impacting image quality and performance. The VILTROX features 9 groups of 11 optical structures, including 4 ED lenses and 3 high refractive index lenses, which contribute to low distortion and high-quality imagery. Meanwhile, the YONGNUO has a simpler construction of 6 elements in 5 groups. This difference may result in the VILTROX producing superior image quality, particularly in challenging lighting conditions or when shooting at wider apertures.
Compatibility with Camera Systems
The VILTROX is designed specifically for Sony's E-mount cameras, including popular models like the a7IV and a6400. Conversely, the YONGNUO is compatible with Canon EF mount cameras, making it an excellent choice for users of Canon DSLR systems. Your choice may depend heavily on the camera system you own, as neither lens is cross-compatible without an adapter.
Value for Money
In terms of value, the YONGNUO offers a lower price point at $132.29 compared to the VILTROX's $180.00, which translates to a savings of about $47.71. For those on a budget, the YONGNUO provides an excellent entry-level option with decent performance for everyday photography. However, the increased price of the VILTROX may be justified by its advanced features and higher optical quality, making it a worthwhile investment for serious photographers.
User Experience and Application
The VILTROX lens is tailored for portrait photography, providing a golden perspective that nicely separates the subject from the background, enhancing the three-dimensional quality of images. The YONGNUO, while versatile, serves as a solid addition to standard lens kits, making it ideal for beginners or casual shooters. Depending on your level of expertise and specific photographic needs, one lens may resonate more than the other in terms of user experience.
Which should you buy?
Choosing between the VILTROX 56mm f/1.7 E Lens and the YONGNUO YN50mm F1.8C Lens ultimately boils down to your camera system and specific photography needs. If you are a Sony user looking for superior image quality and advanced autofocus technology, the VILTROX is likely the better choice despite its higher price. On the other hand, if you are a Canon user and need a budget-friendly lens that still delivers solid performance, the YONGNUO presents an attractive option.
