Price Comparison
The EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens is priced at $67.99, making it significantly more budget-friendly than the VILTROX 85mm F2 EVO FE Lens, which costs $275.00. This means the VILTROX lens is about 304% more expensive than the Lightdow lens. For photographers who are just starting out or those who need a telephoto option without breaking the bank, the Lightdow lens presents an attractive financial choice. However, the higher price of the VILTROX lens may reflect its advanced features and autofocus capabilities, which could justify the investment for professionals looking for quality and performance.
Build Quality and Design
The build quality of the VILTROX 85mm F2 EVO FE Lens is engineered for both durability and usability, featuring a compact and lightweight design at just 340g. This makes it a portable option ideal for handheld shooting over long periods. In contrast, the EF/EF-S 420-800mm F8.3 lens is designed for professional use, with a focus on manual adjustments and a robust build. However, it does not include electronic contacts for focusing, which may require users to switch to manual mode on their cameras. While the Lightdow lens offers adaptability for various Canon models, the VILTROX lens’s ergonomic design enhances user experience, particularly for those who prioritize ease of use.
Focusing Mechanism
The VILTROX 85mm F2 EVO FE Lens features an enhanced autofocus performance powered by a Stepping Motor (STM), which ensures smooth, quiet, and precise focusing. This is particularly beneficial for both photography and video applications. On the other hand, the EF/EF-S 420-800mm F8.3 lens is a fully manual focus lens, emphasizing creative control and skill development. While this manual focus can provide excellent results in the hands of experienced photographers, it may not be suitable for those who prefer the convenience of autofocus, especially in fast-paced shooting environments.
Image Quality
Image quality is a key differentiator between these two lenses. The VILTROX 85mm F2 EVO FE Lens is designed with 10 elements in 8 groups, incorporating Extra-low Dispersion (ED) elements to reduce chromatic aberration, resulting in crisp and vivid images. The Lightdow lens also promises sharp images but focuses on the manual photography experience, which may require more skill to achieve optimal results. While both lenses aim for high-quality output, the VILTROX lens appears to offer superior optical performance that meets professional standards, particularly for portrait photography.
Aperture and Bokeh
The VILTROX lens boasts a wide aperture of F2.0, allowing for excellent light control and creating stunning background bokeh, ideal for portraiture. This feature enables photographers to achieve professional-looking images with a soft background that emphasizes the subject. In comparison, the EF/EF-S 420-800mm lens has an aperture range from F8.3 to F16, which may not provide the same level of creative control over depth of field. Photographers focusing on portrait work will likely find the VILTROX lens more suited to their needs due to its superior ability to create beautiful bokeh effects.
Compatibility
The Lightdow EF/EF-S 420-800mm F8.3 lens is designed specifically for Canon EOS cameras, offering wide compatibility with various models. This makes it a versatile choice for Canon users looking for a telephoto lens. Conversely, the VILTROX 85mm F2 EVO FE Lens is tailored for Sony E-Mount cameras, limiting its use to those within the Sony ecosystem. This difference in compatibility can significantly influence a photographer's decision, depending on the camera system they are using.
Target Audience
The EF/EF-S 420-800mm F8.3 lens is tailored for photographers who enjoy manual control and are looking for an affordable telephoto option for their Canon camera. Its manual focus design can appeal to those who want to enhance their photographic skills. In contrast, the VILTROX 85mm F2 EVO FE Lens is aimed at professionals and enthusiasts who prioritize high-quality portraits and require fast, accurate autofocus. The target audience for each lens is distinct, which can guide potential buyers based on their photographic preferences and needs.
Which should you buy?
When deciding between the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens and the VILTROX 85mm F2 EVO FE Lens, consider your specific photography needs. The Lightdow lens is a budget-friendly choice ideal for Canon users who prefer manual focusing and a versatile zoom range. However, if you're a Sony user seeking a lens that excels in portrait photography with quick autofocus and superior image quality, the VILTROX lens may be worth the higher investment. Ultimately, each lens has its strengths, and your decision should align with your camera system and photographic style.
