Overview of the Lenses
The BENOISON Telephoto Lens for Nikon is priced at $67.99, while the VILTROX 9mm F2.8 E comes at $199.00. This price difference of about 67% highlights the significant disparity between these two lenses, which cater to different photography needs and styles. The BENOISON lens targets those looking for a super telephoto option, while the VILTROX lens is designed for wide-angle photography, especially for users of Sony E-mount cameras.
Target Audience
The BENOISON Telephoto Lens is ideal for wildlife and astrophotography enthusiasts, thanks to its impressive focal length of 420-800mm. This lens is particularly suitable for Nikon DSLR users, requiring manual focus, which could appeal to photographers who enjoy hands-on control over their shots. On the other hand, the VILTROX 9mm F2.8 E is targeted towards vloggers and landscape photographers who need a wide field of view of 113.8°. This lens is perfect for Sony E-mount camera users, offering a lightweight and portable option for creatives on the go.
Build Quality and Design
BENOISON's telephoto lens boasts robust construction, designed to withstand the rigors of outdoor photography. It features a filter size of 62mm and is built with high-quality materials, ensuring durability and longevity. In contrast, the VILTROX lens is lightweight at just 175 grams, making it easy to carry during lengthy shoots. It also includes thoughtful design details, such as a lotus-shaped lens hood to reduce stray light, which enhances its functionality for various shooting conditions.
Focusing Mechanism
The focusing mechanism is a crucial differentiator between these two lenses. The BENOISON Telephoto Lens operates solely in manual focus mode, requiring users to set their cameras to manual mode and adjust the focus ring to achieve clarity in their shots. This may not suit everyone, especially those who prefer the convenience of autofocus. Conversely, the VILTROX 9mm F2.8 E features a reliable autofocus system powered by an STM motor, allowing for fast and accurate focusing. This makes it more user-friendly for casual photographers and vloggers who need quick adjustments.
Optical Performance
Optical performance is a key aspect of any lens. The BENOISON lens offers a fixed aperture of F/8.3-16, which, while effective for telephoto photography, limits versatility in low-light conditions. In comparison, the VILTROX lens features a wider aperture of F2.8, enabling greater light capture and better performance in dim environments. Additionally, the VILTROX lens incorporates 13 elements in 11 groups, including specialized glass elements that enhance image sharpness and reduce distortion. This optical design is beneficial for producing high-quality images, especially in wide-angle photography.
Versatility and Use Cases
When it comes to versatility, each lens serves distinct purposes. The BENOISON Telephoto Lens is perfect for specific use cases like wildlife and moon photography, where distance and zoom capabilities are essential. However, its manual focus can limit its versatility for spontaneous shots. On the other hand, the VILTROX lens excels in various scenarios, from landscape photography to vlogging. Its close focusing distance of just 0.13 meters allows for stunning detail in close-up shots, making it a more adaptable option for a range of shooting situations.
Price Comparison
The BENOISON Telephoto Lens is significantly more affordable at $67.99, making it a compelling option for budget-conscious photographers looking for a telephoto lens. In contrast, the VILTROX 9mm F2.8 E, priced at $199.00, is about 67% more expensive. While the VILTROX lens offers advanced features such as autofocus and a wider aperture, potential buyers need to consider whether the increased cost aligns with their specific photography needs.
Which should you buy?
The decision between the BENOISON Telephoto Lens and the VILTROX 9mm F2.8 E ultimately depends on your photography style and requirements. If you're a Nikon DSLR user focused on wildlife or astrophotography and comfortable with manual adjustments, the BENOISON lens offers an excellent value for its price, especially at $67.99. However, for Sony E-mount users who prioritize versatility, ease of use, and superior optical performance, the VILTROX lens, despite its higher price of $199.00, could be the better investment.
