Price Comparison
The Canon RF 75-300mm f/4-5.6 Lens is priced at $253.95, while the Viltrox 35mm F1.7 E is considerably more affordable at $179.00, making it about 30% cheaper. This price difference could be a significant factor for photographers on a budget. While both lenses offer unique features tailored to different photography styles, the cost-effectiveness of the Viltrox lens might appeal to beginners or casual photographers who do not want to invest heavily in their equipment. Ultimately, the choice may hinge on the specific needs of the photographer in relation to their budget.
Focal Length and Versatility
The Canon RF 75-300mm lens offers a versatile focal range of 75-300mm, which is ideal for sports, wildlife, and portraits. In contrast, the Viltrox 35mm lens provides a fixed focal length equivalent to 35mm on APS-C cameras, making it more suited for portraits and street photography. Photographers looking for flexibility in their shots may find the Canon lens more appealing due to its extensive zoom capabilities. On the other hand, the Viltrox's prime lens design promotes sharpness and high-quality images, which can also be advantageous for specific creative needs.
Aperture and Low-Light Performance
The Viltrox 35mm F1.7 boasts a bright maximum aperture of f/1.7, allowing for excellent low-light performance and control over depth of field. This feature facilitates capturing images in dim conditions while producing a pleasing bokeh effect. In comparison, the Canon RF 75-300mm has a variable aperture range of f/4-5.6, which is less effective in low-light situations. While the Canon lens is versatile for various environments, the Viltrox stands out for its ability to handle challenging lighting, which can be crucial for portrait and street photographers.
Autofocus Capabilities
The Canon RF 75-300mm lens utilizes a DC motor for autofocus, ensuring responsive and accurate focusing suitable for both stills and video. The Viltrox 35mm lens is designed with near-silent autofocus, enhancing the shooting experience, especially for video. Both lenses are compatible with their respective camera systems, but the near-silent operation of the Viltrox may provide an edge for videographers looking to avoid distracting sounds during filming. Each lens thus caters to different needs in terms of focusing technology, depending on whether the user prioritizes stills or video content.
Build Quality and Weight
Weighing in at just over 1 lb (approximately 454 grams), the Canon RF 75-300mm lens is lightweight for a telephoto zoom lens, making it a practical choice for travel and everyday use. The Viltrox 35mm lens is even lighter at only 170g, which emphasizes its portability. While both lenses are designed for ease of use, the significantly lighter weight of the Viltrox lens makes it an attractive option for those who prioritize carrying comfort on longer shoots or while traveling.
Image Quality and Sharpness
The Canon RF 75-300mm lens features an optical design optimized for sharpness and clarity, enhanced by Canon's Super Spectra Coating to minimize lens flare and ghosting. This ensures high contrast and color fidelity, especially in challenging lighting conditions. Meanwhile, the Viltrox 35mm lens is a prime lens, inherently designed to deliver superior sharpness and clarity, particularly at its designated focal length. Photographers focused on achieving the best image quality may lean towards the Viltrox, while those requiring a broader range may appreciate the Canon's versatility alongside its commendable optical performance.
User Experience and Compatibility
The Canon RF 75-300mm lens is specifically made for Canon RF-mount cameras, ensuring a seamless integration with Canon's mirrorless system. In contrast, the Viltrox 35mm lens is compatible with a range of Sony E-mount mirrorless cameras, including popular models like the a6400 and a7iii. Both lenses support advanced features such as EXIF information transmission, enhancing the user experience. However, the choice of lens will ultimately depend on the user's camera system and how well each lens complements their specific setup and shooting style.
Which should you buy?
When deciding between the Canon RF 75-300mm f/4-5.6 Lens and the Viltrox 35mm F1.7 E, the choice largely depends on your specific photography needs and budget. The Canon lens offers a versatile zoom range and is perfect for sports and wildlife photography, making it a strong candidate for those who require flexibility. On the other hand, the Viltrox lens shines in low-light conditions and is significantly lighter, making it ideal for street and portrait photography. If budget is a primary concern, the Viltrox is about 30% cheaper, providing an excellent entry point for photographers. Ultimately, both lenses have their distinct advantages, and your decision should be guided by your unique shooting style and requirements.
