Overview of the Products
The BENOISON Telephoto Lens for Nikon is priced at $67.99, while the EF/EF-S 420-800mm Telephoto Zoom Lens for Canon is slightly cheaper at $65.69. Both lenses are manual focus and designed for specific DSLR camera models, with each targeting different brands—Nikon and Canon respectively. This price difference of about $2.30 makes the Canon lens about 3.4% less expensive than its Nikon counterpart.
Build Quality and Design
Both lenses exhibit robust construction, designed to withstand regular use. The BENOISON lens has been upgraded to an F mount, allowing it to be mounted directly on Nikon DSLR cameras without the need for a T adapter ring. In contrast, the Lightdow lens also emphasizes durability but highlights its fully manual focus experience that encourages photographers to engage deeply with their craft. Both lenses feature a precision manual focus, but the BENOISON is specifically built for Nikon, while the Lightdow lens is compatible with an extensive range of Canon cameras.
Compatibility
Compatibility is a differentiating factor between the two lenses. The BENOISON lens supports a wide range of Nikon DSLR models, including the D850, D7500, and D3500, among others, making it versatile for Nikon users. On the other hand, the Lightdow lens is compatible with numerous Canon models, including the EOS Rebel series and 5D Mark IV, among others. This extensive compatibility makes the Lightdow lens appealing for Canon users who own various models, while Nikon users will find the BENOISON lens to be a suitable option for their specific camera systems.
Aperture and Focal Length
The focal length range for both lenses is identical, spanning from 420mm to 800mm, making them suitable for similar photographic applications like wildlife and moon photography. However, the BENOISON lens has a fixed aperture of F8.3 at 420mm and F16 at 800mm, while the Lightdow lens similarly operates at F8.3 at 420mm and F16 at 800mm. This parity in aperture specifications ensures that both lenses provide comparable performance in terms of light gathering and depth of field, making either lens a solid choice for telephoto photography.
Manual Focus Experience
Both lenses are designed for manual focus, requiring users to operate the focus ring manually to achieve the desired sharpness. The BENOISON lens necessitates that users set their cameras to Manual mode to avoid errors like "Lens not attached." Similarly, the Lightdow lens also requires a switch to Manual mode, and it advises enabling the "Release shutter without lens" option if errors occur. This shared emphasis on manual focus means that both lenses may appeal to photographers looking to enhance their focus skills and artistic creativity through manual control.
Use Cases
The intended use cases for both lenses align closely. The BENOISON lens is particularly suited for wildlife and moon photography, making it an excellent option for hobbyists who enjoy capturing distant subjects. Similarly, the Lightdow lens is touted for its capabilities in capturing detailed images of wildlife, landscapes, and even the moon. Both lenses excel at bringing remote objects closer, making them ideal for enthusiasts looking to explore telephoto photography.

Over a 90-day average, the BENOISON lens has an average price of $64.48, indicating it may be slightly more stable in pricing compared to the Lightdow lens, which has an average price of $62.03.
