Overview of the Products
The EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens is primarily designed for Canon cameras, while the VILTROX 35mm F1.7 E-Mount is tailored for Sony E-Mount cameras. The first lens is priced at $65.69, making it about 63% cheaper than the VILTROX lens, which retails for $179.00. This significant price difference indicates that the two products cater to different user segments and photography needs.
Design and Build Quality
The EF/EF-S 420-800mm lens features a fully manual focus design, emphasizing a hands-on approach for photographers. This design is complemented by a large focus ring and internal focus mechanism, allowing for precise adjustments. In contrast, the VILTROX 35mm lens boasts a lightweight design at just 170 grams, making it portable for spontaneous shoots. While the EF/EF-S lens leans towards a more traditional, robust construction, the VILTROX lens is designed for modern convenience and ease of use.
Autofocus vs. Manual Focus
The VILTROX 35mm features efficient and reliable autofocus, equipped with a built-in STM stepping motor. This allows for precise tracking focus and supports eye/face autofocus, making it ideal for dynamic shooting situations. Conversely, the EF/EF-S 420-800mm lens requires full manual focus, which can be challenging for beginners but provides a unique opportunity for photographers to develop their skills. The choice between these focusing systems largely depends on the user’s experience level and shooting style.
Aperture and Light Performance
With a maximum aperture of F1.7, the VILTROX 35mm lens excels in low-light conditions and offers beautiful natural bokeh, thanks to its nine aperture blades. This feature is particularly beneficial for portrait and street photography, where background blur enhances the subject's prominence. On the other hand, the EF/EF-S 420-800mm lens has an aperture range of F8.3 to F16, making it less suited for low-light scenarios but effective for capturing distant subjects, such as wildlife and landscapes, with clarity.
Compatibility and Versatility
The EF/EF-S 420-800mm lens is compatible with a wide range of Canon cameras, including models from the Rebel series to the 5D Mark IV. This extensive compatibility enhances its versatility for Canon users. Meanwhile, the VILTROX 35mm lens is designed for Sony E-Mount cameras, which include popular models like the A7 series and ZV-E10. While both lenses are versatile within their respective ecosystems, the choice will depend on the camera system already in use.
Photography Use Cases
The EF/EF-S 420-800mm lens is ideal for capturing distant subjects and excels in scenarios like wildlife photography, moon shots, and sports events. Its long focal length allows photographers to bring faraway subjects closer with remarkable detail. In contrast, the VILTROX 35mm lens is suited for everyday photography, including street, portrait, and event photography, thanks to its wide aperture and effective autofocus. Each lens serves its niche, catering to different photography styles and needs.
Price Comparison and Value
At $65.69, the EF/EF-S 420-800mm lens is significantly less expensive than the VILTROX 35mm lens, which is priced at $179.00. This makes the EF/EF-S lens about 63% cheaper, offering a budget-friendly option for photographers who require long-range capabilities without breaking the bank. However, the VILTROX lens provides advanced features such as autofocus and a larger aperture, which may justify its price for those seeking quality in everyday photography.
Which should you buy?
Choosing between the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens and the VILTROX 35mm F1.7 E-Mount lens ultimately depends on your specific needs and camera system. If you are a Canon user looking for a budget-friendly telephoto option focused on distant subjects, the EF/EF-S lens is an excellent choice. However, if you prioritize autofocus capabilities, low-light performance, and a lightweight design for versatile photography, the VILTROX lens is worth the investment. Both lenses offer unique advantages, so consider your shooting style and preferences before making a decision.
