Build Quality and Design
In terms of build quality, the VILTROX 20mm f2.8 FE weighs a compact 157g, making it a lightweight option for photographers on the go. Its sleek design is particularly appealing for those who prefer to travel light. On the other hand, the YONGNUO YN50mm 50mm f/1.8 is slightly heavier at 203g but still maintains a portable design, thanks to its high-precision metal bayonet and gold-plated contacts. Both lenses are crafted for durability, but the VILTROX edges out in terms of sheer portability.
Autofocus Performance
The VILTROX 20mm f2.8 FE boasts fast autofocus capabilities, which enhance its performance in capturing fast-moving subjects. This feature is particularly beneficial for street photography or dynamic environments. In contrast, the YONGNUO YN50mm 50mm f/1.8 includes an automatic/manual switching function for intuitive aperture control, allowing for accurate depth of field and exposure adjustments. While both lenses excel in autofocus, the VILTROX might have an edge in speed, making it suitable for action shots.
Aperture and Low Light Performance
When it comes to aperture, the YONGNUO YN50mm 50mm f/1.8 shines with its large f/1.8 aperture, perfect for creating beautifully blurred backgrounds and performing well in low-light scenarios. This lens is ideal for portraiture and artistic shots. In contrast, the VILTROX 20mm f2.8 FE has a maximum aperture of f/2.8, which is still effective but does not provide the same level of background separation or low-light advantage. If low-light performance is a priority, the YONGNUO lens stands out in this category.
Focal Length and Versatility
The VILTROX 20mm f2.8 FE features a wide-angle focal length of 20mm, suitable for expansive landscapes and architectural photography. Its minimum focus distance of 0.62 feet allows for versatile shooting options. The YONGNUO YN50mm 50mm f/1.8, with a focal length of 50mm, offers a standard perspective that closely resembles the human eye, making it versatile for various photography styles, including street and portrait photography. This difference in focal length influences the types of shots each lens excels at, appealing to different user preferences.
Optical Quality
Both lenses promise optical excellence, but they achieve it through different designs. The VILTROX 20mm f2.8 FE comprises 10 elements in 8 groups, including two ED lenses and two aspherical lenses, which contribute to its sharpness and clarity. Meanwhile, the YONGNUO YN50mm 50mm f/1.8 has a simpler optical structure of 6 elements in 5 groups, still providing high-definition results through its nano-coating technology. While both lenses are designed to minimize distortion, the VILTROX may offer slightly superior sharpness due to its more complex design.
Suitable Camera Compatibility
Camera compatibility is a crucial factor when choosing a lens. The VILTROX 20mm f2.8 FE is specifically designed for Sony e-Mount cameras, including models like the a7CR and a6600. In contrast, the YONGNUO YN50mm 50mm f/1.8 is compatible with a wide range of Nikon F-Mount cameras, including popular models such as the D3000 and D5000 series. Thus, your choice may depend heavily on the camera system you are using, as both lenses cater to different brands.
Pricing and Value for Money
Price-wise, the YONGNUO YN50mm 50mm f/1.8 is significantly cheaper at $102.00, making it a great option for those on a budget. The VILTROX 20mm f2.8 FE, while more expensive at $176.00, offers features that may justify the price for professional photographers. The price difference of approximately $74 reflects the varying target audiences, with VILTROX appealing to serious enthusiasts and professionals willing to invest in high-quality glass, while YONGNUO offers an accessible entry point for beginners.
Which should you buy?
Choosing between the VILTROX 20mm f2.8 FE and the YONGNUO YN50mm 50mm f/1.8 largely depends on your specific photography needs and camera compatibility. If you prioritize wide-angle shots and compact design, the VILTROX is an excellent choice. However, if you focus on portrait photography, low-light performance, and budget-friendliness, the YONGNUO offers significant advantages. Ultimately, your decision should align with the type of photography you plan to pursue, ensuring you select the lens that best fits your creative vision.
