Price Comparison

The VILTROX 35mm f1.7 Fuji is priced at $179.00, while the YONGNUO YN50mm 50mm f/1.8 is about 43% cheaper at $102.00. This significant price difference may appeal to budget-conscious photographers or those just starting with prime lenses. While the VILTROX offers advanced features and a larger aperture for low-light performance, the YONGNUO provides an economical option without sacrificing too much on quality. For photographers prioritizing cost, the YONGNUO emerges as a compelling choice.

Aperture and Low-Light Performance

The VILTROX 35mm f1.7 Fuji shines with a larger maximum aperture of f/1.7, enabling exceptional low-light performance and beautiful background blur. This makes it ideal for portraits and street photography. On the other hand, the YONGNUO YN50mm 50mm f/1.8 also boasts a large aperture but at f/1.8. While it produces impressive bokeh and performs well in low-light conditions, it slightly lags behind the VILTROX in terms of light-gathering capability. The difference in aperture can influence the creative possibilities for photographers working in challenging lighting environments.

Lens Construction and Optical Quality

When it comes to optical design, the VILTROX features 11 elements in 9 groups, including high refractive and extra-low dispersion elements, which work together to minimize chromatic aberrations and distortion. The YONGNUO, while also well-constructed, has an optical structure of 6 elements in 5 groups. Although both lenses aim to deliver crisp, clear images, the VILTROX's more complex design suggests a potential edge in optical performance, especially for critical applications demanding high image quality.

Autofocus Performance

The VILTROX 35mm f1.7 Fuji is equipped with a new STM motor, offering fast and precise autofocus with minimal focus breathing, which is beneficial for video recording. The YONGNUO YN50mm 50mm f/1.8 also features an autofocus system, but the description does not highlight the same level of sophistication as the VILTROX. This could affect the overall shooting experience, particularly for videographers who require smooth focus transitions. For those who prioritize speedy and accurate autofocus, the VILTROX may be the more attractive option.

Focal Length and Versatility

The VILTROX has a focal length of 35mm, which provides a perspective similar to the human eye, making it suitable for a wide range of photography styles from landscapes to portraits. In contrast, the YONGNUO offers a classic 50mm focal length, often considered a standard for portrait photography. While both lenses are versatile, the choice between 35mm and 50mm can significantly influence the type of photography one can effectively pursue. The VILTROX may be preferable for those looking for a more general-purpose lens, while the YONGNUO could excel in portrait-specific applications.

Minimum Focusing Distance

The VILTROX features a minimum focusing distance of just 0.33 meters (33cm), allowing for stunning close-up shots with incredible detail. The YONGNUO, with a minimum focus distance of 0.45m (1.5ft), also offers good close-up capabilities but is not quite as close-focusing as the VILTROX. This difference can be crucial for photographers interested in macro-style shots or detailed product photography. The VILTROX's closer focusing distance enhances its versatility, making it suitable for a wider range of shooting scenarios.

Build and Design

Both lenses offer thoughtful design features, but they cater to slightly different needs. The VILTROX lens includes an extended lens hood for improved image contrast and stray light protection, along with a USB-C upgrade port for firmware updates. This level of design consideration may appeal to tech-savvy photographers who want to stay current with their equipment. The YONGNUO lens, while compact and lightweight at around 203g, emphasizes portability, making it an excellent choice for travel. Each lens has its strengths: the VILTROX for tech features and image quality, and the YONGNUO for ease of use on the go.

Which should you buy?

Choosing between the VILTROX 35mm f1.7 Fuji and the YONGNUO YN50mm 50mm f/1.8 ultimately depends on your specific needs and budget. If low-light performance, advanced autofocus, and optical quality are your top priorities, the VILTROX is worth the investment at $179.00. However, if you're looking for an economical option that still delivers solid performance for portrait photography, the YONGNUO at $102.00 is a strong contender. Both lenses have unique advantages, making them suitable for different photographers based on their shooting styles and budget constraints.
