Rokinon vs YONGNUO YN50mm F1.8C Lens, Large Aperture Auto Focus Lens,

Overview

The Rokinon 14mm f/2.8 IF ED Super Lens for Canon EF and the YONGNUO YN50mm F1.8C Lens cater to different photography needs, showcasing distinct strengths in their respective categories. The Rokinon lens is priced at $231.25, while the YONGNUO lens offers a more budget-friendly option at $132.29, making it about 43% cheaper than the Rokinon. Choosing between these lenses depends largely on the type of photography you intend to pursue.

Image Quality

The Rokinon 14mm lens emphasizes superior image quality with its advanced optical design, featuring 14 elements in 10 groups. This configuration is specifically crafted for exceptional sharpness and clarity, making it ideal for landscape and astrophotography. The lens also incorporates aspherical elements to minimize distortion, ensuring images maintain accurate color rendition and sharpness from edge to edge. In contrast, the YONGNUO lens, while offering good edge-to-edge sharpness, is primarily designed for low-light performance with its larger maximum aperture of f/1.8. It supports both manual and autofocus functions, making it versatile for everyday photography.

Focal Length and Perspective

The Rokinon lens provides an ultra-wide focal length of 14mm, offering a remarkable 115.7° angle of view, which is perfect for capturing expansive scenes like landscapes and real estate. This lens is particularly advantageous in scenarios requiring a broader perspective. On the other hand, the YONGNUO lens features a 50mm focal length, which is more suitable for portrait photography, delivering a natural perspective that closely resembles human vision. The difference in focal lengths caters to distinct photographic needs, allowing photographers to select a lens that best fits their shooting style.

Low-Light Performance

Low-light performance is a critical factor for many photographers, and here the YONGNUO lens shines with its f/1.8 maximum aperture. This feature allows for brighter images in dim conditions, making it an excellent choice for indoor or evening shoots. The Rokinon lens, although it has a respectable f/2.8 aperture, does not quite match the YONGNUO's capability in low-light situations. Thus, if low-light versatility is a priority, the YONGNUO lens offers a clear advantage.

Build Quality

The Rokinon lens is constructed with a robust and reliable build, weighing 31.7oz (900g) and designed for professional use in various conditions. Its durable design suggests it can withstand the rigors of outdoor photography. Conversely, the YONGNUO lens is significantly lighter and more compact at roughly 2 inches in length, making it easily portable. While the Rokinon is suited for more demanding environments, the YONGNUO's lightweight design may appeal to those who prioritize convenience and ease of use.

Manual Focus vs. Autofocus

The Rokinon lens features a precision manual focus option, which allows for fine-tuning and creative effects, especially useful for professional photographers who prefer complete control over their shots. The YONGNUO lens, however, supports both autofocus and manual focus, offering more versatility for users who may not want to spend time adjusting focus manually. This dual functionality makes the YONGNUO lens user-friendly, especially for beginners or those looking for a quick shooting experience.

Compatibility

Both lenses are designed for Canon EF mount cameras, ensuring compatibility with a broad range of Canon DSLRs. However, the Rokinon lens is also adaptable to various other camera mounts with different versions available, enhancing its usability across different systems. In contrast, the YONGNUO lens is primarily tailored for Canon EF mounts but works seamlessly with numerous Canon models, including the 5D and 7D series. If you anticipate switching systems in the future, the Rokinon lens may provide more flexibility.

Which should you buy?

Ultimately, the decision between the Rokinon 14mm f/2.8 IF ED Super Lens and the YONGNUO YN50mm F1.8C Lens boils down to your specific photographic needs. If you are focused on landscape or astrophotography and require an ultra-wide perspective with superior image quality, the Rokinon lens is worth the investment at $231.25. However, for those seeking a versatile, budget-friendly option that excels in low-light conditions and provides a natural perspective, the YONGNUO lens at $132.29 presents a compelling choice. Each lens has its unique advantages, making it essential to consider how you plan to use them before making a final decision.
