Overview of the Lenses
The EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens is priced at $67.99, while the VILTROX 56mm f/1.7 E Lens costs $180.00. This makes the EF/EF-S lens about 62% cheaper than the VILTROX lens. Each lens serves different photography needs, with the former being a super telephoto option suited for long-distance shots and the latter designed for portrait photography with a wide aperture.
Design and Build Quality
The EF/EF-S 420-800mm lens features a fully manual focus design, promoting a hands-on approach that appeals to photographers seeking precision in their work. It is built for compatibility with a wide range of Canon cameras, ensuring its utility for various models, including the EOS Rebel series and the 5D Mark IV. In contrast, the VILTROX 56mm f/1.7 E Lens is compact and lightweight at just 170 grams, making it easy to carry for extended shoots. Its autofocus capabilities and modern design cater to those who prefer a more automated experience.
Focusing Mechanism
The EF/EF-S 420-800mm lens is entirely manual, requiring photographers to adjust focus manually. This promotes a deeper understanding of photographic techniques but may not suit everyone, particularly beginners. On the other hand, the VILTROX lens employs an STM silent motor for efficient and reliable autofocus, making it more user-friendly for novices or anyone looking to capture spontaneous moments without manual adjustments.
Image Quality
The EF/EF-S lens boasts UMC technology to minimize aberrations and flare, which can lead to sharp images with beautiful background bokeh. Its design allows for a range of aperture settings, from f/8.3 at 420mm to f/16 at 800mm, providing versatility in various lighting conditions. The VILTROX 56mm lens offers a fast f/1.7 aperture, ideal for low-light situations and creating a soft background blur that enhances portrait photography. With its nine groups of 11 optical structures, including four ED lenses, it promises excellent image quality with low distortion.
Intended Use Cases
The EF/EF-S lens is tailored for professional photographers who need a long-range telephoto option for wildlife, sports, or landscape photography. Its manual focus design encourages users to engage with their craft more deeply. Conversely, the VILTROX lens is perfect for portrait photographers looking to achieve a flattering perspective, with a full-frame equivalent focal length of about 85mm. This makes it suitable for capturing human subjects with a pleasing depth of field.
Compatibility
The EF/EF-S 420-800mm lens is compatible with a wide range of Canon cameras, making it an excellent choice for those already invested in the Canon ecosystem. It is designed to work seamlessly without any additional adapters for most models. Meanwhile, the VILTROX 56mm lens is specifically engineered for Sony APS-C E mount cameras, including popular models like the a7IV and a6400. This focus on compatibility means that users must consider their existing camera systems when deciding between these lenses.
Price Comparison
The EF/EF-S 420-800mm lens is priced at $67.99, making it a budget-friendly option for photographers who need a telephoto lens without breaking the bank. In contrast, the VILTROX 56mm lens is priced at $180.00, which is about 2.65 times more expensive than the EF/EF-S lens. This significant price difference reflects the varying capabilities and design philosophies of the two products, with the VILTROX lens offering modern features like autofocus and a wider aperture.
Which should you buy?
Choosing between the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens and the VILTROX 56mm f/1.7 E Lens ultimately depends on your photography needs. If you seek a budget-friendly, manual-focus option for long-distance photography, the EF/EF-S lens is a solid choice at $67.99. However, if you require a versatile, fast autofocus lens for portrait work and are willing to invest $180.00, the VILTROX lens is superior in functionality and image quality.
