BENOISON 420-800mm Telephoto Lens - F Lens for Nikon DSLR vs 420-800mm Telephoto Lens - F Mount for Nikon SLR

Price Comparison

BENOISON 420-800mm is £5.77 cheaper than JINTU 420-800mm, representing a saving of about 7.5%. At £71.22, the BENOISON model is priced at 93% of the JINTU’s current cost of £76.99. While both lenses are in a similar price bracket, this difference makes the BENOISON a more economical option without any indication of reduced functionality.

Compatibility and Mount Type

The BENOISON lens features an upgraded F mount that allows direct mounting on Nikon DSLR cameras without requiring a T adapter ring. This eliminates the need for additional accessories and ensures a more secure fit. The JINTU lens also uses an F mount and supports the same range of Nikon SLR models, including D850, D750, D500, and D3500 series. Both lenses are compatible with the full list of Nikon F-mount DSLRs listed in their descriptions, offering identical camera support despite differing brand claims.

Focus System and Operation

Both lenses are fully manual focus with no autofocus motor or electronic contacts. This means photographers must use Manual (M) mode on their camera to operate either lens. The focus ring is located near the front of the barrel, and users must manually rotate it slowly until the subject appears sharp. Neither lens displays aperture values correctly on the camera—both will show F-- or F00 due to missing electronic communication. The operational experience is therefore identical across both products.

Aperture and Zoom Range

Each lens offers a fixed focal length range of 420–800mm and an aperture that automatically adjusts based on zoom position: f/8.3 at 420mm and f/16 at 800mm. The aperture range is non-adjustable and consistent between the two models. This means neither lens allows manual control over aperture settings, which affects exposure management and depth of field. Photographers must compensate using shutter speed and ISO to achieve correct exposure, a factor common to both.

Build Quality and Design

Both lenses are described as built with high-quality materials and robust construction, designed to be durable and long-lasting. They share the same filter size—62mm—and are noted as being full frame compatible. The BENOISON model specifically highlights its sturdy build, while the JINTU description emphasises adaptability and creative freedom. Despite different phrasing, both imply similar physical durability and design intent, with no differences evident in material quality or structural details from the provided data.

User Experience and Practical Tips

Both products require careful handling due to the lack of electronic contacts. Users are advised to switch the camera to Manual (M) mode immediately after attaching the lens to avoid errors. If issues persist, enabling “Release shutter w/o lens” in the camera menu is recommended for both models. The JINTU lens explicitly warns about potential error messages and includes guidance on how to resolve them. The BENOISON description mentions the camera may display F-- but does not provide troubleshooting steps beyond switching to M mode. This suggests slightly more detailed user guidance from JINTU, though both ultimately rely on the same operational workflow.

Which should you buy?

Choose the BENOISON 420-800mm if you want a reliable, F-mount telephoto lens for Nikon DSLRs at a lower price point—£71.22 versus £76.99. It offers identical compatibility, zoom range, aperture characteristics, and manual focus operation as the JINTU model. Its upgraded F mount allows direct attachment without extra adapters, matching the JINTU’s core functionality. While the JINTU provides slightly more detailed usage tips, the BENOISON delivers better value for money and performs identically in every measurable way. For photographers seeking a cost-effective, durable telephoto solution for wildlife, moon, or distant landscape photography, the BENOISON is the superior choice.
