Overview of the Products
When comparing the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens and the YONGNUO YN35mm F2 Lens, a clear distinction arises in their intended use and target audience. The EF/EF-S 420-800mm F8.3 is priced at $67.99, making it about 36% cheaper than the YONGNUO YN35mm F2, which retails for $106.00. This price difference reflects the versatility offered by the telephoto lens, while the wide-angle lens caters to a different set of needs for photographers.
Design and Build Quality
The design and build quality of these lenses differ significantly, reflecting their respective functions. The EF/EF-S 420-800mm features a professional manual focus design that emphasizes stability and durability, catering to serious photographers who value precise control over their shots. In contrast, the YONGNUO YN35mm F2 is designed for ease of use, offering both auto focus and manual focus modes. This design flexibility makes it suitable for a broader audience, especially beginners looking for an affordable option without sacrificing quality.
Optical Performance
In terms of optical performance, the EF/EF-S 420-800mm excels with its super telephoto capabilities, allowing for remarkable background bokeh and sharp images, thanks to its UMC technology that minimizes aberrations and flare. It operates at an aperture range of f/8.3 to f/16 depending on the focal length, which is ideal for distant subjects. Conversely, the YONGNUO YN35mm F2 provides a fast aperture of F/2, making it better suited for low-light conditions. This lens has a minimum focusing distance of only 0.25m, enabling close-ups that capture wide-angle perspectives effectively.
Compatibility
Compatibility is another critical factor in this comparison. The EF/EF-S 420-800mm is designed specifically for Canon EOS cameras, with wide compatibility across various models, including the Rebel series and the professional 5D Mark IV. On the other hand, the YONGNUO YN35mm F2 also supports Canon EF mount cameras, making it versatile for both full-frame and APS-C formats. However, the extensive compatibility of the EF/EF-S 420-800mm with numerous Canon models gives it an edge for users with a range of Canon gear.
Usability and Focus Mechanism
Usability is a key point of differentiation. The EF/EF-S 420-800mm is fully manual, requiring photographers to switch their cameras to manual mode after installation, which may pose a learning curve for some users. This manual focus design encourages skill development but may not suit everyone. In contrast, the YONGNUO YN35mm offers both AF and MF modes, allowing for a more straightforward shooting experience, particularly beneficial for those unfamiliar with manual focusing techniques.
Price and Value
In terms of price and value, the EF/EF-S 420-800mm is priced at $67.99, making it a more budget-friendly option compared to the YONGNUO YN35mm, which costs $106.00. This represents a significant price difference of about 36%. While the YONGNUO lens offers a fast aperture and versatile shooting modes, the EF/EF-S lens provides a unique telephoto range that can be invaluable for specific photographic situations, such as wildlife or sports photography.
Target Audience
The target audience for each lens is distinct. The EF/EF-S 420-800mm is aimed at professional photographers or serious hobbyists who seek to explore manual photography and require a lens that can handle long-range shots with precision. Meanwhile, the YONGNUO YN35mm F2 is designed for beginners and enthusiasts looking for an affordable lens that can deliver excellent optical performance in a variety of settings, including low-light situations.
Which should you buy?

If you prioritize versatility and are comfortable with manual controls, the EF/EF-S lens is an excellent choice at a lower price of $67.99. However, if you prefer a user-friendly lens that excels in low-light conditions and offers both auto and manual focus options, the YONGNUO YN35mm at $106.00 might be the better fit. Each lens serves its purpose well, catering to different types of photography enthusiasts.
