Factors to Consider Before Purchasing a 50mm Prime Lens
50mm prime lenses, like the Yongnuo YN50mm F1.8S, are a popular choice for photographers because they offer a versatile focal length ideal for portraits, street photography, and even some landscape shots. They generally excel in image quality due to their simple design. The ideal customer for a 50mm prime lens is someone looking for a relatively inexpensive lens that offers excellent image quality and a shallow depth of field for creative blurring. However, this lens type is not for everyone. If you need a zoom lens for varied perspectives, or require a lens with image stabilization, a 50mm prime lens might not be suitable. In those cases, you’d be better off considering a zoom lens with image stabilization features.
Before buying any 50mm lens, consider your budget, desired image quality, autofocus needs (AF vs. MF), and compatibility with your camera body. Research different brands and read reviews before making a decision. Understanding your shooting style and needs will help you select the perfect lens for you.

Introducing the Yongnuo YN50mm F1.8S Lens
The Yongnuo YN50mm F1.8S is a 50mm prime lens designed for Sony E-mount cameras. It boasts a large F1.8 aperture, which allows for excellent low-light performance and beautiful background blur (bokeh). The lens promises sharp images and reliable autofocus, all at a fraction of the cost of comparable lenses from major brands. This lens aims to deliver professional-quality results without the professional price tag, particularly for enthusiasts and intermediate users. Unlike its higher-priced counterparts, the Yongnuo 50mm lens lacks in-body image stabilization.
- Pros:
- Affordable price
- Fast and relatively quiet autofocus
- Excellent image quality for the price
- Lightweight and compact design
- Good low-light performance
- Cons:
- All-plastic construction can feel less robust.
- Some chromatic aberration in high-contrast scenes
- Autofocus can hunt in very low light or challenging conditions.
Exploring the Features and Benefits of the YN50mm F1.8S
Autofocus Performance
One of the YN50mm F1.8S‘s most surprising strengths is its autofocus. While not as lightning-fast as Sony’s top-tier lenses, it’s remarkably quick and accurate for its price point. The DSM (Digital Stepping Motor) is impressively quiet, making it suitable for video recording. In most shooting scenarios, the autofocus is responsive and reliable, providing a smooth and efficient focusing experience.
Image Quality and Sharpness
The image quality produced by the Yongnuo YN50mm F1.8S is truly impressive. Sharpness is excellent in the center of the frame, and even the edges maintain impressive detail, especially when shooting at f/2.8 and beyond. While it’s not entirely free from chromatic aberration (especially in high-contrast areas), it’s easily manageable in post-processing. The F1.8 aperture allows for shallow depth of field effects, producing beautiful background blur. Overall, the image quality surpasses what you’d expect from a budget lens, delivering vibrant, detailed photos and videos.
Build Quality and Design
The lens is entirely constructed of plastic, which is its most significant drawback. While it’s lightweight and portable, the plastic feels less durable than metal construction. However, it feels surprisingly sturdy and has held up well even after extensive use. The lens mount is also made of plastic, which occasionally feels slightly less secure than the metal mounts you will find on other more expensive lenses, but this has not proven a significant issue. The included lens hood provides essential protection from stray light.
Low-Light Capabilities
The F1.8 maximum aperture is a game-changer in low-light photography. The lens allows you to shoot at faster shutter speeds and lower ISO settings, reducing noise and maintaining image quality even in dim lighting. This has been incredibly helpful for shooting in various indoor and nighttime scenarios, dramatically improving my low-light shooting capabilities.
Firmware Updates
The ability to update the YN50mm F1.8S lens firmware through the camera body is another welcome feature. This means you can easily get the latest updates to enhance performance and address any potential bugs. While not as seamless as using a dedicated USB connection, the in-camera update functionality is a significant upgrade over lenses that require external upgrades. This ensures that the lens remains compatible and updated with the latest camera technology.
Real User Experiences with the YN50mm F1.8S
Many online reviews echo my positive experience. Users consistently praise the lens’s surprisingly good autofocus, excellent image quality considering the price, and lightweight design. While some users note the all-plastic construction, few report it negatively impacting the lens’s durability. The overwhelmingly positive sentiment towards the YN50mm F1.8S confirms its value for money and overall performance.
Final Verdict: A Budget-Friendly Lens Worth Considering
The Yongnuo YN50mm F1.8S solves the problem of needing a high-quality, versatile lens without breaking the bank. Its fast and quiet autofocus, coupled with its impressive image quality, makes it an excellent choice for both photos and videos. While the all-plastic construction may not appeal to everyone, the lens’s affordability and exceptional performance more than compensate for that minor drawback. If you’re looking for a budget-friendly lens for your Sony E-mount camera, I highly recommend checking this one out. To purchase your own YN50mm F1.8S Lens, click here.
