VILTROXYONGNUO YN50mm F1.8 Lens Large Aperture Auto Focus

Price Comparison

The VILTROX 85mm F2 EVO FE Lens is priced at $275.00, while the YONGNUO YN50mm F1.8 Lens comes in significantly lower at $82.00. This makes the YONGNUO lens approximately 70% cheaper than the VILTROX lens. For photographers on a budget or those just starting with portrait photography, the YONGNUO offers an accessible entry point without sacrificing essential features. However, the higher price of the VILTROX lens may be justified by its advanced specifications and capabilities, especially for serious photographers looking for higher-quality results.

Aperture and Image Quality

The VILTROX 85mm boasts a wide F2.0 aperture, which allows for stunning background bokeh and precise light control, making it ideal for professional-looking portraits. In contrast, the YONGNUO features a slightly wider F1.8 aperture, which also helps to create a virtual background effect, adding a different dimension to photography. While the difference in aperture size is minimal, it can affect the depth of field and overall aesthetic of the images produced. Photographers may prefer the VILTROX for its enhanced sharpness and color accuracy due to its advanced optical design, which includes 10 elements in 8 groups, helping to reduce chromatic aberration.

Autofocus Performance

The autofocus capabilities of the VILTROX lens are driven by a Stepping Motor (STM), which ensures smooth, quiet, and precise autofocus, suitable for both photography and video. This can be particularly beneficial for videographers or those shooting in environments where noise is a concern. Conversely, the YONGNUO lens supports both auto focus and manual focus modes, catering to a wider range of shooting styles. This versatility can be appealing for users who want more control over their focus settings. However, the VILTROX's more advanced autofocus technology may provide a noticeable advantage in fast-paced shooting scenarios.

Build Quality and Design

The VILTROX lens is designed to be compact and lightweight, weighing only 340 grams and measuring φ69mm x 76mm. This portability makes it an excellent choice for photographers who need to carry their equipment for extended periods. The lens is also built to endure challenging conditions, ensuring reliable performance even in adverse weather. On the other hand, the YONGNUO, while not specified for weight or dimensions, is designed to be compatible with full-frame and APS-C format cameras, appealing to a broad range of users. Both lenses are engineered to be user-friendly, but VILTROX’s robust design could be a significant factor for those who shoot in less than ideal conditions.

Focusing Distance

The VILTROX lens offers a close-up focusing distance of just 0.74 meters, allowing for detailed close-up shots. This feature is particularly advantageous for portrait photographers looking to capture intricate details in their subjects. The YONGNUO lens, with a focus distance of 0.45 meters, provides a slightly closer range, making it versatile for various shooting scenarios. However, the difference in minimum focusing distance may not be as critical for all photographers. Those who often shoot portraits may find the VILTROX lens more appealing due to its superior optical performance at closer distances.

Compatibility

Compatibility is an essential consideration for photographers when choosing a lens. The VILTROX 85mm is specifically designed for Sony E-Mount cameras, including models like the a7IV and a7C II. This specialization means that it may not be suitable for users of other camera brands. In contrast, the YONGNUO YN50mm is compatible with Canon EF mount cameras, providing flexibility for Canon users. If you already own a camera, the choice of lens will be largely dictated by compatibility, which may limit options for some photographers.

User Experience and Features

Photographers will appreciate the user experience offered by both lenses. The VILTROX lens features advanced optical design elements, such as Extra-low Dispersion (ED) elements, which enhance color accuracy and sharpness. This attention to detail can result in higher-quality images that stand out. The YONGNUO lens includes useful features like a focus distance indicator, which helps photographers measure shooting distance and depth of field effectively. Both lenses have their unique advantages, but the advanced features of the VILTROX may cater more to professionals seeking superior image quality.

Which should you buy?

Choosing between the VILTROX 85mm F2 EVO FE Lens and the YONGNUO YN50mm F1.8 Lens ultimately depends on your specific needs and budget. If you are a professional photographer who prioritizes image quality, autofocus performance, and build quality, the VILTROX lens may be worth the investment at $275.00. However, if you are a hobbyist or starting out in photography, the YONGNUO lens offers an excellent value at $82.00 and provides decent performance with its large aperture and versatile features. Consider your camera compatibility, shooting style, and the importance of advanced features when making your decision.
