Both lenses cater to different shooting styles and camera systems, offering unique features that can enhance your photography experience.
Price Comparison
The EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens is priced at $65.69, while the VILTROX AF 50mm F2.0 Air Z Lens comes in at $199.00. This makes the EF/EF-S lens about 67% cheaper than the VILTROX lens. If you're on a budget, the EF/EF-S lens provides an economical option for those looking to experiment with telephoto photography. However, the higher price of the VILTROX lens reflects its advanced features, such as autofocus capabilities and a larger aperture.
Compatibility and Mounting
The EF/EF-S 420-800mm lens is designed specifically for Canon cameras, compatible with a wide range of models including the EOS Rebel series and various 5D models. In contrast, the VILTROX AF 50mm lens is tailored for Nikon Z mount cameras, including popular models like the Z6 and Z7. If you are a Canon user, the EF/EF-S lens is a clear choice, while Nikon photographers will find the VILTROX lens to be a better fit for their gear.
Focus Mechanism
The EF/EF-S 420-800mm lens features a fully manual focus design, which may appeal to photographers seeking total control over their settings. This lens requires users to adjust parameters such as shutter speed and aperture manually, enhancing the learning experience. On the other hand, the VILTROX AF 50mm lens boasts an autofocus system powered by a stepping motor, which ensures precise and efficient focusing. This makes it ideal for quick shots and dynamic scenes, particularly in portrait and street photography.
Aperture and Depth of Field
The EF/EF-S 420-800mm lens has a variable aperture range of f/8.3 to f/16, which is adequate for capturing distant subjects. However, the VILTROX AF 50mm lens offers a larger maximum aperture of f/2.0, allowing for impressive depth of field control and beautiful bokeh effects. This wider aperture is particularly useful for low-light conditions and portrait photography, where subject isolation is desired. The larger aperture of the VILTROX lens enhances its versatility, making it suitable for various photography styles.
Weight and Portability
The EF/EF-S 420-800mm lens is notably heavier than the VILTROX AF 50mm lens, which weighs only 220 grams. This difference in weight can be significant for photographers who prioritize portability and ease of handling. The lightweight design of the VILTROX lens makes it an attractive option for travel and street photography, where carrying additional weight can be a burden. Conversely, the EF/EF-S lens, while bulkier, offers extensive focal range capabilities ideal for wildlife and distant subject photography.
Image Quality and Optical Design
The VILTROX AF 50mm lens is designed with an optical structure that includes 13 elements in 9 groups, featuring three ED lenses and a high-refractive element. This advanced design contributes to vivid, distortion-free images that are ideal for a range of shooting scenarios. The EF/EF-S 420-800mm lens, although it employs UMC technology to minimize aberrations and flare, may not match the optical sophistication of the VILTROX lens. Photographers looking for high-quality image performance will appreciate the superior optical design of the VILTROX lens.
Use Cases and Versatility
The EF/EF-S 420-800mm lens excels in capturing distant subjects, making it perfect for wildlife and landscape photography. Its telephoto range allows photographers to frame shots of far-off subjects with clarity. In contrast, the VILTROX AF 50mm lens is more versatile, suitable for portraits, street photography, and everyday documentation. Its wide aperture and fast autofocus capabilities make it a great all-rounder for various shooting situations.
Which should you buy?
Ultimately, the choice between the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens and the VILTROX AF 50mm F2.0 Air Z Lens depends on your specific photography needs and the camera system you use. If you're a Canon user seeking an affordable lens for capturing distant subjects, the EF/EF-S lens is a solid choice. However, if you're a Nikon photographer looking for a versatile lens that excels in low-light conditions and offers excellent image quality, the VILTROX lens is worth the investment. Consider your shooting style, budget, and camera compatibility to make the best decision for your photography journey.
