Overview of VILTROX AF 28mm F4.5 and YONGNUO 35MM F1.8
The VILTROX AF 28mm F4.5 is priced at $99.00, while the YONGNUO 35MM F1.8 comes in at $128.00, making the VILTROX about 23% cheaper. Both lenses cater to different camera mounts and types, targeting Fujifilm and Sony users respectively. The VILTROX lens is designed for wide-angle photography, while the YONGNUO offers a standard focal length with a larger aperture, making them appealing for various photographic styles.
Design and Build Quality
In terms of design, the VILTROX AF 28mm F4.5 is exceptionally lightweight, weighing only 60g and measuring just 15.3mm in thickness. This makes it highly portable and ideal for on-the-go shooting. The Yongnuo 35MM F1.8, on the other hand, has a robust build with a metal bayonet and outer shell, ensuring durability. While the VILTROX lens features an innovative slide cap design that transforms into a lens cap, the YONGNUO lens is equipped with a dustproof and waterproof rubber ring, making it suitable for various environments.
Optical Performance
Both lenses promise impressive optical performance, but they cater to different user needs. The VILTROX features six elements in six groups, including two ED and two aspherical lenses, which help deliver sharp images and vibrant colors. Additionally, it creates beautiful starburst effects, adding a unique touch to photography. The YONGNUO lens utilizes ten elements in nine groups, including ultra-low dispersion glass lenses, enabling it to effectively suppress chromatic aberration. It also supports human eye recognition, enhancing its utility for portrait photography.
Autofocus Capabilities
Autofocus performance varies between the two lenses. The VILTROX AF 28mm is equipped with a built-in VCM motor that ensures quick and precise autofocus, supporting face and eye recognition, which is particularly useful for portrait and candid photography. In contrast, the YONGNUO 35MM F1.8 boasts a very quiet autofocus system, making it suitable for video recording without the distraction of noise. Both lenses excel in their autofocus capabilities, but the choice may depend on whether users prioritize speed or silence.
Aperture and Low-Light Performance
The VILTROX AF 28mm F4.5 offers a maximum aperture of f/4.5, which is adequate for general shooting but may limit low-light performance compared to the YONGNUO. The YONGNUO 35MM F1.8, with its maximum aperture of f/1.8, allows for significantly more light to enter, making it a better choice for low-light environments and for achieving a shallow depth of field. This substantial difference in aperture size could be a deciding factor for photographers who frequently shoot in challenging lighting conditions.
Compatibility and Versatility
Compatibility is crucial when selecting a lens, and both lenses serve different camera systems. The VILTROX AF 28mm is specifically designed for Fuji X-mount cameras, including models like the X-T5 and X-H2. In contrast, the YONGNUO 35MM F1.8 is compatible with a broader range of Sony E-mount mirrorless cameras, including the popular A7 series and ZV-E1. This wider compatibility makes the YONGNUO a more versatile option for Sony users looking to expand their lens collection.
Price and Value Proposition
When comparing price points, the VILTROX AF 28mm F4.5 is currently priced at $99.00, which is a significant savings compared to the YONGNUO 35MM F1.8, which retails for $128.00. This price difference of $29.00 makes the VILTROX a more budget-friendly option for photographers, especially beginners or those looking for a lightweight travel lens. However, the YONGNUO’s features, such as a larger maximum aperture and compatibility with a wider range of cameras, may justify its higher price for serious enthusiasts and professionals.
Which should you buy?
Choosing between the VILTROX AF 28mm F4.5 and the YONGNUO 35MM F1.8 largely depends on your specific photography needs and camera system. If you're a Fujifilm user looking for a lightweight, wide-angle lens with unique optical effects, the VILTROX is an excellent choice at $99.00. Conversely, if you’re a Sony user who prioritizes low-light performance and versatility with a broader range of compatible cameras, the YONGNUO is worth the extra investment at $128.00. Ultimately, both lenses offer compelling features, but your camera system and shooting style will guide the best choice for you.
