Canon RF75-VILTROX

Price Comparison

The Canon RF75-300mm F4-5.6 Zoom Lens is priced at $239.00, while the VILTROX 35mm F1.7 E-Mount Prime Lens is available for $179.00. This makes the VILTROX lens about 25% cheaper than the Canon lens, offering a more budget-friendly option for photographers. The price difference may influence buyers on a budget or those just starting in photography, as savings can be redirected towards additional accessories or gear.

Lens Type and Versatility

The Canon RF75-300mm is a zoom lens, providing a focal length range of 75mm to 300mm, making it versatile for various photography styles, from landscapes to wildlife. In contrast, the VILTROX 35mm is a prime lens with a fixed focal length, which promotes sharper images and better low-light performance due to its F1.7 aperture. While the zoom lens allows for different compositions without changing lenses, the prime lens excels in creating beautiful bokeh and artistic effects, which can appeal to portrait photographers.

Autofocus Performance

Autofocus capabilities differ significantly between the two lenses. The Canon RF75-300mm features Servo AF technology, which allows for eye detection even at the full 300mm zoom, ensuring precise focus on moving subjects. On the other hand, the VILTROX 35mm lens uses a built-in STM stepping motor for efficient autofocus, which supports eye/face AF to enhance tracking accuracy. While both lenses provide reliable autofocus, the Canon lens may be more suitable for dynamic shooting scenarios, whereas the VILTROX lens is particularly beneficial for stationary subjects in creative portraiture.

Build Quality and Weight

The Canon RF75-300mm is designed to be compact and lightweight, making it portable and easy to carry, similar to a 500ml water bottle. This is a significant consideration for photographers who prioritize mobility. Conversely, the VILTROX 35mm weighs only 170g, further enhancing its portability and making it ideal for casual shooting or travel photography. Both lenses emphasize portability, but the VILTROX lens has a slight edge in weight, making it easier to handle for extended periods.

Optical Quality

Optical performance varies between the two lenses based on their designs. The Canon RF75-300mm offers a versatile zoom range, allowing for dynamic framing options, but may not achieve the same sharpness as a prime lens. In contrast, the VILTROX 35mm boasts 11 elements in 9 groups, including an ED lens and high refractive index elements, contributing to its high-quality images with minimal distortion. Photographers looking for superior optical quality may prefer the VILTROX lens for its potential to produce sharper images with beautiful background blur.

Compatibility

Compatibility is crucial for potential buyers to consider. The Canon RF75-300mm is designed exclusively for Canon EOS R series cameras, such as the R100, R50, and R6, limiting its use to specific models. In contrast, the VILTROX 35mm is compatible with a wide range of Sony E-Mount cameras, including popular models like the A7C, A7RII, and FX3. This broader compatibility makes the VILTROX lens a more versatile option for Sony users looking to expand their lens collection.

Included Accessories

When considering the value of each lens, the included accessories can make a difference. The Canon RF75-300mm comes with a UV filter, lens cap keeper, and a cleaning kit, which adds to its value by providing essential items for lens maintenance and protection. In comparison, the VILTROX 35mm lens does not specify included accessories, which could lead to additional costs for necessary items. The added accessories with the Canon lens may appeal to those who want a more complete package right out of the box.

Which should you buy?

Choosing between the Canon RF75-300mm F4-5.6 Zoom Lens and the VILTROX 35mm F1.7 E-Mount Prime Lens ultimately depends on your specific needs as a photographer. If you require a versatile zoom lens for various photography styles and appreciate the additional included accessories, the Canon lens is a solid choice. However, if you prioritize a budget-friendly option with superior optical quality and portability for capturing stunning portraits, the VILTROX lens stands out. Consider your camera compatibility and shooting preferences to make the best decision for your photography journey.
