Overview of the BENOISON Telephoto Lens for Nikon

The BENOISON Telephoto Lens for Nikon is priced at $67.99, making it a budget-friendly option for photographers looking for a super telephoto lens. This manual focus lens offers a focal length of 420-800mm, providing versatility for wildlife and astronomical photography. With a fixed aperture ranging from F/8.3 to F/16, users will need to manage exposure manually, which can appeal to those who enjoy hands-on photography.

Overview of the YONGNUO YN50mm F1.8 Lens

The YONGNUO YN50mm F1.8 Lens is available at $82.00, making it about 21% more expensive than the BENOISON lens. This lens features a large aperture of F1.8, allowing for beautiful depth of field effects and excellent low-light performance. It supports both auto focus and manual focus modes, making it a versatile choice for Canon EF mount cameras. Its multi-coated lens structure enhances light transmittance, appealing to those who prioritize image quality.

Compatibility and Use Cases

The BENOISON Telephoto Lens is specifically designed for Nikon DSLR cameras, compatible with a wide range of models including the D3500 and D850. Its manual focus operation requires photographers to set their camera mode to M (Manual), which can be an obstacle for those accustomed to automatic settings. In contrast, the YONGNUO YN50mm lens is compatible with Canon EF mount cameras and supports multiple shooting modes like M/AV/TV/P, making it user-friendly for various photography styles.

Focus Mechanism

A key distinction between these two lenses is their focusing mechanism. The BENOISON lens is a manual focus lens, which means users must manually adjust the focus ring to achieve clarity in their shots. This can provide a more engaged shooting experience but may deter those looking for convenience. On the other hand, the YONGNUO lens supports auto focus, making it easier for photographers who prefer quick adjustments without manual intervention.

Aperture and Exposure Control

The BENOISON lens offers a fixed aperture ranging from F/8.3 at 420mm to F/16 at 800mm. This non-adjustable aperture may limit creativity in exposure settings, especially in varying lighting conditions. In contrast, the YONGNUO lens boasts a large F1.8 aperture that allows for more creative depth of field and better performance in low-light situations. This difference in aperture capabilities makes the YONGNUO more versatile for various shooting environments.

Build Quality and Durability

The BENOISON Telephoto Lens is built with high-quality materials, promising durability and long-lasting use. Its robust construction is ideal for outdoor photography, particularly for capturing wildlife or celestial events. The YONGNUO lens also features a solid build, with gold plating on the metal contacts to improve signal conductivity and corrosion resistance. While both lenses are designed for longevity, the BENOISON's super telephoto capability may appeal to users who need a lens that can withstand the rigors of outdoor shooting.

Price Comparison

At $67.99, the BENOISON lens is an economical option for photographers who need a telephoto solution without breaking the bank. In contrast, the YONGNUO lens is priced at $82.00, making it approximately 21% more expensive. While the YONGNUO offers features like auto focus and a larger aperture, the BENOISON’s price point may be more suitable for hobbyists or those just starting in photography.

Which should you buy?

Choosing between the BENOISON Telephoto Lens and the YONGNUO YN50mm F1.8 lens ultimately depends on your needs and camera compatibility. If you own a Nikon DSLR and are interested in capturing distant subjects like wildlife or the moon, the BENOISON lens offers a compelling price point and a long focal range. However, if you prefer a versatile lens that supports auto focus and excels in low-light conditions, the YONGNUO would be a better investment despite its higher price. Consider your photography style and which features matter most to you before making a decision.
