Priced at $67.99, it offers a significant focal range, making it ideal for wildlife and sports photography. This lens is fully manual, requiring users to adjust focus and exposure settings manually, which can enhance learning and creative control. In contrast, the YONGNUO YN50mm F1.8N Standard Prime Lens, priced at $102.00, serves as a more traditional option for Nikon DSLR users, focusing on portrait and general photography with its large aperture for low-light situations.

Price Comparison

When comparing prices, the EF/EF-S 420-800mm lens comes in about 33% cheaper at $67.99 compared to the YONGNUO YN50mm, which retails for $102.00. This pricing difference may be a crucial factor for budget-conscious photographers who need a telephoto option without breaking the bank. While both lenses offer unique features, the significant price gap could influence purchasing decisions, especially for those entering the photography field or those who primarily shoot in specific conditions.

Compatibility and Versatility

The EF/EF-S 420-800mm lens is designed specifically for Canon cameras, including models like the T8i, T7i, and 90D. Its compatibility with a wide range of Canon DSLRs makes it a versatile choice for users who already own or plan to acquire Canon equipment. On the other hand, the YONGNUO YN50mm F1.8N lens is tailored for Nikon DSLRs and supports APS-C and full-frame formats, making it a solid choice for Nikon users looking for a reliable prime lens. While both lenses cater to different camera brands, the user’s existing gear will heavily influence which lens is the better fit.

Autofocus vs. Manual Focus

One of the standout features of the YONGNUO YN50mm lens is its dual-focus capability; it supports both autofocus (AF) and manual focus (MF) modes, providing flexibility for users who want ease of use and precision. In contrast, the EF/EF-S 420-800mm lens is fully manual, which can be challenging for some but also offers creative freedom and precise control over adjustments. This manual operation is particularly appealing to photographers looking to refine their skills. However, beginners may find the YONGNUO’s autofocus feature more user-friendly.

Optical Performance

The EF/EF-S 420-800mm lens is engineered for professional photographers, featuring UMC technology that minimizes aberrations and flare, resulting in sharp images with excellent background bokeh. It also has a unique aperture range that adjusts based on focal length, achieving f/8.3 at 420mm and f/16 at 800mm. In comparison, the YONGNUO YN50mm F1.8N boasts a large f/1.8 aperture, making it particularly effective in low-light conditions while also delivering a pleasing depth of field for portraiture. Each lens excels in different photographic contexts, highlighting the importance of selecting based on specific needs.

Build Quality and Design

The EF/EF-S 420-800mm lens is built for durability, featuring a robust design that ensures stability during extensive use. Its fully manual operation encourages a hands-on approach, allowing photographers to engage more deeply with their craft. Meanwhile, the YONGNUO YN50mm lens features gold-plated metal contacts that enhance signal conductivity and corrosion resistance, indicating a focus on reliability and longevity. While both lenses are designed with quality in mind, the choice may come down to whether a photographer prioritizes manual creativity or the convenience of autofocus.

User Experience

Photographers using the EF/EF-S 420-800mm lens can expect a learning experience that emphasizes manual control, enhancing their photography skills over time. This lens encourages users to adjust settings like shutter speed and ISO manually, fostering a deeper understanding of photography. Conversely, the YONGNUO YN50mm lens offers a more straightforward user experience with its autofocus capabilities, making it suitable for novice photographers who may prefer simplicity while developing their skills. Each lens caters to different user preferences, emphasizing the importance of understanding personal photography goals.

Which should you buy?

Choosing between the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens and the YONGNUO YN50mm F1.8N comes down to your specific photography needs and camera system. If you are a Canon user looking for a budget-friendly option with a broad focal range and are comfortable with manual focus, the EF/EF-S 420-800mm lens is a compelling choice. However, if you are a Nikon user seeking a lens that offers both autofocus convenience and low-light performance for portraits, the YONGNUO YN50mm lens is worth the investment. Ultimately, your decision should reflect your camera compatibility and the type of photography you wish to pursue.
