Price Comparison

The EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens is priced at $67.99, while the YONGNUO 35MM F1.8 Art Auto Focus Lens is priced at $128.00. This makes the telephoto zoom lens about 47% cheaper than the prime lens. For photographers on a budget, the lower price point of the EF/EF-S lens may be more appealing, especially for those looking to explore telephoto photography without a substantial investment. However, the price difference also reflects the distinct functionalities and target users of each lens, where the YONGNUO lens is designed for a different type of photography.

Build Quality and Design

The build quality of both lenses reflects their intended use, but they cater to different photographer needs. The YONGNUO 35MM lens features a metal bayonet and outer shell, which adds to its durability and lends a premium feel typical of high-quality lenses. In contrast, while the EF/EF-S 420-800mm lens does not specify its material composition, it is designed for manual focus, which may imply a simpler build for ease of use. Both lenses are equipped with features that enhance usability, such as a dustproof and waterproof rubber ring on the YONGNUO lens, making it suitable for various environments.

Compatibility

The EF/EF-S 420-800mm lens boasts wide compatibility with Canon's extensive range of DSLR cameras, including models like the Rebel T8i, T7i, and 90D, among others. This versatility allows photographers to use it across multiple camera bodies, making it a great option for Canon users. On the other hand, the YONGNUO 35MM lens is specifically designed for Sony E-mount mirrorless cameras, supporting models such as the A7RIII and A9. This focused compatibility could be a deciding factor for those already invested in either Canon or Sony ecosystems.

Focusing Mechanism

The EF/EF-S 420-800mm lens features a fully manual focus design that provides photographers with precise control over their shots. This can be highly beneficial for experienced users who appreciate the ability to fine-tune focus settings according to their creative vision. In contrast, the YONGNUO 35MM lens features a quiet auto-focus system, making it suitable for both photography and video recording. This difference in focusing mechanisms highlights the varied user experiences each lens offers, appealing to different levels of expertise and shooting styles.

Aperture and Image Quality

The YONGNUO 35MM lens has a wide maximum aperture of F1.8, allowing for excellent low-light performance and beautiful background bokeh, which is ideal for portrait photography and creative shooting. The EF/EF-S 420-800mm lens, while offering a maximum aperture of F8.3 at 420mm and F16 at 800mm, is designed primarily for telephoto photography, emphasizing long-distance shooting over low-light capabilities. Therefore, the choice between the two will largely depend on the photographer's specific needs—whether they prioritize low-light versatility or long-range capture.

Target Audience

Each lens targets different segments of photographers. The EF/EF-S 420-800mm lens is aimed at those who enjoy landscape, wildlife, or sports photography, where long focal lengths are essential. Its manual focus might attract enthusiasts who wish to refine their skills and have greater control over their images. Conversely, the YONGNUO 35MM lens is tailored for more general photography and videography, with features that cater to beginners and intermediate users looking for quality without extensive manual adjustments.

Performance in Use

Both lenses provide distinct photography experiences. The EF/EF-S 420-800mm lens allows for a unique photographic journey through manual adjustments, which not only enhances the skills of the photographer but also supports artistic creativity. The YONGNUO 35MM lens, however, stands out with its advanced optical design, featuring 10 elements in 9 groups and 9 aperture blades, ensuring high image quality and effective aberration compensation. This design enables photographers to capture sharp images with pleasing depth-of-field effects, making it an excellent choice for those who prioritize image quality.

Which should you buy?

Ultimately, the choice between the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens and the YONGNUO 35MM F1.8 Art Auto Focus Lens will depend on your specific photography needs and equipment compatibility. If you're a Canon user looking for a budget-friendly option that excels in telephoto photography, the EF/EF-S lens is a compelling choice at $67.99. However, if you're invested in the Sony mirrorless system and seek a versatile, high-quality lens for a variety of shooting scenarios, the YONGNUO lens, priced at $128.00, offers excellent performance and ease of use.
