Overview of the BENOISON Telephoto Lens and YONGNUO 50mm Lens
The BENOISON Telephoto Lens is priced at $67.99, making it a budget-friendly option for photographers seeking a manual focus lens with a super telephoto range. In contrast, the YONGNUO 50mm lens is priced at $102.00, which is approximately 50% higher. This comparison will explore the unique features and benefits of each lens, helping you determine which may be the better fit for your photography needs.
Lens Type and Focus Mechanism
The BENOISON Telephoto Lens is exclusively a manual focus lens, requiring users to adjust the focus ring manually. This can be a disadvantage for those used to autofocus systems, as it necessitates switching the camera to manual mode to avoid errors. The YONGNUO 50mm lens, however, provides both automatic and manual focus options, giving users more flexibility and ease, especially in dynamic shooting situations. The presence of autofocus may appeal to those who prioritize convenience and speed in capturing images.
Aperture and Low Light Performance
With a fixed aperture of F/8.3-16, the BENOISON Telephoto Lens is suitable for bright conditions but may struggle in low-light scenarios. In contrast, the YONGNUO 50mm lens features a large aperture of F/1.8, allowing for superior low-light performance. This makes the YONGNUO a better choice for indoor photography or evening shoots, as it can effectively capture images with minimal light and create beautiful background blur. The difference in aperture size is significant, as the YONGNUO lens can generate a creamy bokeh that enhances portrait photography.
Focal Length and Versatility
The BENOISON Telephoto Lens offers an impressive focal length range of 420-800mm, making it ideal for wildlife or distant landscape photography. This extensive zoom capability allows photographers to capture subjects from a significant distance without sacrificing detail. Conversely, the YONGNUO 50mm lens is a standard prime lens that excels in versatility for various photography styles, including portraits and street photography. While the BENOISON lens is highly specialized for long-range shooting, the YONGNUO caters to a broader range of everyday photography needs.
Build Quality and Portability
The construction of the BENOISON Telephoto Lens emphasizes durability, with high-quality materials designed to withstand the rigors of outdoor shooting. However, it does not provide specific weight information. The YONGNUO 50mm lens, on the other hand, is lightweight at around 203g, making it an excellent choice for travel and everyday use. Its compact design, combined with a high-precision metal bayonet, enhances its portability. For photographers who prioritize carrying a lightweight kit, the YONGNUO lens stands out as a practical option.
Compatibility with Camera Models
Both lenses boast compatibility with a wide range of Nikon DSLR cameras, but their specific use cases differ. The BENOISON Telephoto Lens is designed for various models, including the D3500, D850, and D7500, while focusing exclusively on the F mount. The YONGNUO 50mm lens also supports a broad array of Nikon F mount cameras, including the D3000, D5000, and D80 series. This extensive compatibility makes both lenses suitable choices for Nikon users, but the BENOISON lens is particularly advantageous for those seeking telephoto capabilities.
Price Comparison and Value for Money
The BENOISON Telephoto Lens, at $67.99, is significantly more affordable compared to the YONGNUO 50mm lens, which retails for $102.00. This price difference of about $34.01 translates to a 50% increase in cost for the YONGNUO lens. While the BENOISON offers excellent value for those needing a telephoto option, the YONGNUO lens justifies its price with superior features, such as a larger aperture and dual focus capabilities. Depending on your photographic needs, the value proposition varies greatly between these two options.
Which should you buy?
Choosing between the BENOISON Telephoto Lens and the YONGNUO 50mm lens ultimately depends on your photography style and requirements. If you are focused on capturing distant subjects and have experience with manual focus, the BENOISON lens provides excellent value and versatility at a lower price point. However, if you prioritize low-light performance, ease of use with autofocus, and a lens that can handle a variety of photographic scenarios, the YONGNUO 50mm lens is worth the additional investment. Each lens has its strengths, and the best choice will align with your specific photography goals.
