Price Comparison
The Canon RF 50mm F1.8 STM lens is priced at $219.00, while the VILTROX 35mm F1.7 E-Mount lens is slightly cheaper at $179.00. This makes the VILTROX lens approximately 17% cheaper than the Canon lens. When considering budget constraints, the price difference may influence buyers who are looking for a quality lens without stretching their finances too much. Ultimately, the lower cost of the VILTROX can provide significant savings, especially for those just starting to build their lens collection.
Aperture and Bokeh Quality
The Canon RF 50mm F1.8 STM lens features a wide f/1.8 aperture, which is well-suited for portraits and creates beautiful background blur. In contrast, the VILTROX 35mm F1.7 lens offers an even larger aperture of f/1.7, allowing for even more pronounced bokeh effects. This difference in aperture size means that the VILTROX lens can produce a more artistic blur, making it a strong option for photographers who prioritize depth of field and subject isolation in their work. Both lenses excel in low-light conditions, but the VILTROX provides a slight edge in achieving that coveted dreamy background.
Autofocus Performance
Autofocus capabilities are crucial for many photographers, and both lenses boast impressive features. The Canon RF 50mm F1.8 STM utilizes an STM motor that ensures smooth, fast, and near-silent autofocus. This is particularly beneficial for video work and capturing spontaneous moments. On the other hand, the VILTROX 35mm F1.7 also employs a built-in STM stepping motor, which not only provides precise autofocus but supports advanced features like eye and face detection. This added functionality makes the VILTROX lens particularly appealing for portrait photographers who need reliable focus on their subjects.
Optical Design and Quality
The optical design of the lenses plays an important role in image quality. The Canon RF 50mm F1.8 STM lens includes an aspheric lens element, which helps reduce distortion and improve overall sharpness. Meanwhile, the VILTROX 35mm F1.7 lens has a more complex structure with 11 elements in 9 groups, including 1 ED lens and 1 aspherical lens. This sophisticated design, coupled with high-definition multi-layer coating, suggests that the VILTROX may deliver superior image quality, especially in challenging lighting conditions. Photographers looking for the best optical performance may find the VILTROX lens to be a compelling option.
Weight and Portability
Portability is a key factor for many photographers, especially those who frequently shoot on location. The Canon RF 50mm F1.8 STM lens is lightweight and compact, though the VILTROX 35mm F1.7 takes portability to the next level with a weight of just 170 grams. This lightweight construction makes it easier to carry around during long shoots or while traveling. For photographers who prioritize mobility without sacrificing performance, the VILTROX lens is particularly appealing, as it allows for spontaneous shooting opportunities in various environments.
Compatibility and Use Cases
The Canon RF 50mm F1.8 STM lens is designed specifically for EOS R-Series cameras, making it an excellent choice for Canon users. Conversely, the VILTROX 35mm F1.7 lens is compatible with a wide range of Sony E-mount cameras, including popular models like the A7 series and FX3. This broad compatibility means that the VILTROX can cater to a larger audience, especially those who own different Sony cameras. Photographers must consider their existing equipment when choosing between these two lenses, as compatibility can significantly impact their shooting experience.
Brand Reputation and Trust
Canon is a well-established brand with a long history of producing reliable and high-quality lenses, which may instill confidence in potential buyers. VILTROX, while newer, has gained a positive reputation for offering innovative and affordable alternatives. Both brands have their strengths, but the choice may ultimately depend on personal preference and previous experiences. For those who value brand legacy and reliability, Canon may be the preferred choice, while budget-conscious photographers may lean towards the VILTROX for its cost-effectiveness and robust performance.
Which should you buy?
Choosing between the Canon RF 50mm F1.8 STM lens and the VILTROX 35mm F1.7 E-Mount lens boils down to your specific needs and preferences. If you prioritize a wider aperture for beautiful bokeh, the VILTROX is the better option at $179.00. However, if you are a Canon user looking for a reliable, well-regarded lens, the Canon RF 50mm F1.8 STM at $219.00 is a solid choice. Ultimately, both lenses offer excellent performance, but your camera system compatibility and budget will guide your final decision.
