The lens construction consists of 6 elements in 5 groups, which contributes to its excellent image quality. Additionally, the lightweight design (approximately 5.6 oz) enhances its portability for everyday use.
Overview of the VILTROX 35mm F1.7 E-Mount Lens
The VILTROX 35mm F1.7 E-Mount lens is slightly more expensive at $179.00, positioning it about 6% higher in price than the Canon lens. This lens is tailored for Sony E-Mount cameras and offers a larger aperture of f/1.7, which not only enhances low-light performance but also creates a striking bokeh effect with its 9 aperture blades. Weighing only 170g, it remains compact and easy to carry, making it ideal for spontaneous shooting scenarios. With a construction of 11 elements in 9 groups, including special lenses for improved quality, it holds significant appeal for serious photographers.
Autofocus Capabilities
The Canon EF 50mm f/1.8 STM features a stepping motor (STM) that provides near-silent autofocus, making it an excellent choice for both still photography and video. This technology ensures smooth and quick focus adjustments, which can be crucial for capturing fleeting moments, especially in dynamic settings. It supports full-time manual focus, allowing for precise control when needed.
In contrast, the VILTROX 35mm F1.7 also boasts a built-in STM for efficient autofocus. This lens is specifically designed for face and eye detection, providing enhanced tracking capabilities. The VILTROX lens focuses quickly and reliably, minimizing latency during use. Both lenses provide solid autofocus performance, but the VILTROX offers additional features beneficial for portrait photographers.
Image Quality and Performance
The Canon EF 50mm f/1.8 STM is praised for its sharp image quality and excellent color balance, thanks to its updated lens arrangement and coatings that reduce ghosting and flare. The lens performs well in various lighting conditions, making it suitable for a range of photography styles including portraits, action shots, and night photography.
Similarly, the VILTROX 35mm F1.7 aims for high-quality image production, with its optical structure designed to minimize distortion and enhance clarity. The inclusion of one ED lens and one aspherical lens improves the overall image quality, making it a strong contender for those seeking crisp, detailed photos. Both lenses excel in their respective categories, but the choice may ultimately come down to the specific needs of the photographer.
Design and Build Quality
The Canon EF 50mm f/1.8 STM is designed with a rugged metal mount, which adds to its durability while maintaining a lightweight form factor. Its compact size makes it easy to carry, allowing photographers to have it on hand for various shooting opportunities.

Its portability is a significant advantage for photographers who often find themselves on the go. Additionally, the lens includes a micro USB interface for future firmware upgrades, ensuring it remains relevant as technology evolves. This feature underscores the VILTROX's commitment to adaptability and longevity.
Compatibility with Camera Systems
The Canon EF 50mm f/1.8 STM is compatible with Canon’s EOS series cameras, functioning effectively on both full-frame and APS-C models. The 50mm focal length translates to an 80mm effective length on APS-C cameras, making it a versatile option for a variety of shooting situations.
Conversely, the VILTROX 35mm F1.7 is designed exclusively for Sony E-Mount cameras, which may limit its appeal to users of other brands. However, it supports a wide range of Sony models, including popular choices like the A7 series and the FX3, making it a solid option for Sony enthusiasts. The choice of lens may depend significantly on the camera system in use.
Price Comparison
The Canon EF 50mm f/1.8 STM is priced at $169.00, while the VILTROX 35mm F1.7 comes in at $179.00. This makes the Canon lens about $10 cheaper, or approximately 6% more affordable than the VILTROX lens. While both lenses are reasonably priced for their respective features, the slight price advantage of the Canon model may appeal to budget-conscious buyers. However, the additional features of the VILTROX, including the larger aperture and advanced autofocus capabilities, may justify the higher price for some users.
Which should you buy?
Choosing between the Canon EF 50mm f/1.8 STM and the VILTROX 35mm F1.7 ultimately depends on your specific needs and camera system. The Canon lens is an excellent all-rounder that provides great value for money, particularly for those using Canon cameras. It excels in low-light conditions and offers reliable performance for stills and video alike. Conversely, the VILTROX lens is designed with Sony E-Mount users in mind, offering advanced autofocus features and a slightly larger aperture for artistic photography. If you are a Sony user looking for a lens that provides modern features and excellent image quality, the VILTROX may be the better choice. However, if you prioritize affordability and versatility, the Canon remains a strong contender.
