Overview of the Products
The EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens is priced at $65.69, making it a budget-friendly option for Canon DSLR users. In contrast, the VILTROX 35mm f1.7 Fuji lens commands a higher price of $179.00, appealing to Fujifilm X Mount users who prioritize advanced features. While the Lightdow lens is significantly cheaper, the VILTROX offers more sophisticated technology and a brighter aperture.
Target Audience
The EF/EF-S 420-800mm lens is geared towards photographers who prefer manual focus, allowing them to exercise their skills and creativity. This lens is ideal for those interested in wildlife, moon, and landscape photography. Conversely, the VILTROX 35mm lens targets photographers who require speed and precision, particularly in portrait and street photography. Its autofocus capability caters to users looking for convenience and efficiency in their shooting experience.
Aperture and Low-Light Performance
The VILTROX 35mm f1.7 excels in low-light conditions with its bright f/1.7 aperture, which allows for stunning background blur and bokeh. This makes it particularly suitable for portrait and street photography. In comparison, the EF/EF-S 420-800mm lens features an aperture range of f/8.3 to f/16, making it less ideal for low-light situations. While the Lightdow lens is capable of capturing distant subjects, it lacks the low-light performance that the VILTROX offers.
Focal Length and Versatility
With a focal length of 420-800mm, the EF/EF-S 420-800mm lens provides exceptional telephoto capabilities, enabling photographers to capture detailed images of distant subjects. This makes it an excellent choice for wildlife and landscape photography. On the other hand, the VILTROX 35mm lens offers a more versatile focal length of 35mm, which is comparable to the human eye. This makes it suitable for a broader range of photography styles, from landscapes to portraits, enhancing its versatility.
Autofocus vs. Manual Focus
The VILTROX 35mm f1.7 features fast and precise autofocus, making it a prime choice for those who prefer quick and efficient shooting. The autofocus system minimizes focus breathing, which is beneficial for video recording as well. In contrast, the EF/EF-S 420-800mm lens is a fully manual focus lens, which requires photographers to manually adjust settings. While this provides greater control over focus, it may not appeal to those who favor the convenience of autofocus.
Build Quality and Design
Both lenses have thoughtful design elements. The VILTROX 35mm has an extended lens hood for better protection against stray light, while the EF/EF-S 420-800mm features a large focus ring for precision adjustments. However, the VILTROX's optical design includes 11 elements in 9 groups, optimized for quality, including high-refractive and aspherical elements. This potentially provides better image quality than the EF/EF-S, which focuses on manual operation rather than advanced optical performance.
Price Comparison
The EF/EF-S 420-800mm lens is priced at $65.69, which is about 63% less expensive than the VILTROX 35mm, retailing at $179.00. This significant price difference makes the Lightdow lens a compelling option for those on a budget or those who are just beginning their photography journey. However, the higher cost of the VILTROX is justified by its advanced features and capabilities, making it an investment for serious photographers.
Which should you buy?
Choosing between the EF/EF-S 420-800mm and the VILTROX 35mm f1.7 ultimately depends on your photography style and needs. If you are a Canon DSLR user looking for a budget-friendly lens that excels in capturing distant subjects, the EF/EF-S 420-800mm is a solid choice. However, if you are a Fujifilm user seeking versatility, low-light performance, and fast autofocus, the VILTROX 35mm f1.7 is worth the investment. The decision hinges on whether you prioritize price and manual control or advanced features and convenience.
