Overview

The BENOISON Telephoto Lens for Nikon and the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens for Canon are both manual focus lenses priced at $67.99. They target photographers looking for versatile telephoto capabilities without the complexity of autofocus systems. While both lenses offer similar focal lengths, their compatibility and features reflect the needs of different camera systems.

Compatibility

The BENOISON Telephoto Lens is designed for Nikon DSLR cameras, boasting compatibility with a wide range of models, including the D3500, D850, and D7500. This makes it an excellent choice for Nikon users who want to capture distant subjects like wildlife or celestial bodies. On the other hand, the EF/EF-S 420-800mm lens caters specifically to Canon users, compatible with models such as the EOS Rebel T8i, T7i, and 90D. Both lenses require manual focus, but the BENOISON lens stands out with its upgraded F mount, which allows for direct attachment to Nikon DSLRs without needing a T adapter ring.

Manual Focus Experience

Both lenses offer a fully manual focus experience, enhancing the photographer's control over their images. The BENOISON lens requires users to manually adjust the focus ring, while the EF/EF-S lens encourages photographers to engage with manual settings for shutter speed, ISO, and aperture. This hands-on approach not only fosters skill development but also promotes artistic creativity. The BENOISON lens emphasizes that it does not support autofocus, meaning users must operate their cameras in manual mode to avoid errors, while the EF/EF-S lens provides warm tips for ensuring proper setup to avoid "no lens" errors.

Optical Performance

In terms of optical performance, both lenses feature a focal length range of 420-800mm with a similar maximum aperture of F8.3 at 420mm and F16 at 800mm. The BENOISON lens, however, is built with high-quality materials that promise durability, making it a robust option for outdoor photography. The EF/EF-S lens incorporates UMC technology, which minimizes aberrations and flare, resulting in sharper images and enhanced background bokeh. While both lenses aim for excellent image quality, the EF/EF-S lens's advanced optical technology may provide a slight edge in clarity and detail.

Build Quality

Both lenses are constructed with durability in mind, but the BENOISON lens highlights its robust build as a significant feature. This aspect is particularly beneficial for photographers who frequently shoot in challenging outdoor environments. The EF/EF-S lens also offers good build quality but focuses more on the user experience with features like a large focus ring and internal focusing mechanism, enhancing ease of use during manual adjustments. Ultimately, while both lenses are designed to withstand regular use, the BENOISON lens may appeal more to those prioritizing ruggedness in their gear.

Price and Value

Both lenses are priced identically at $67.99, offering an attractive entry point for photographers seeking telephoto capabilities. However, the EF/EF-S lens shows a slightly better average price over the past 90 days at $61.92, which could suggest it may be more routinely available at a lower cost. This price parity means that while the initial investment is the same, potential savings might tilt slightly towards the Canon lens if you consider its average pricing trend.

Target Audience

The BENOISON Telephoto Lens is tailored for Nikon DSLR users, particularly those interested in wildlife and astrophotography. Its manual focus design may appeal to photographers looking to refine their skills and control over their shots. Conversely, the EF/EF-S lens is geared towards Canon users who appreciate the creative freedom of manual focusing while having the benefit of a lens that is compatible with a broader range of Canon cameras. Each lens effectively serves its brand's user base, making them both suitable for their respective audiences.

Which should you buy?

Choosing between the BENOISON Telephoto Lens for Nikon and the EF/EF-S 420-800mm Telephoto Zoom Lens for Canon ultimately boils down to your camera system and personal preferences. If you are a Nikon user looking for a robust manual focus lens with an upgraded F mount, the BENOISON lens is an excellent option. However, if you shoot with Canon and seek a lens that may offer better optical performance and potentially lower average pricing, the EF/EF-S lens could be the right choice. Both lenses deliver exceptional value at their price point, making them worthwhile investments for manual focus photography enthusiasts.
