The Canon EF-S 18-135mm f/3.5-5.6 IS STM is a versatile zoom lens priced at $329.95. It is designed for both video and still photography, making it an ideal choice for a range of shooting scenarios. This lens features a refined Image Stabilization system that provides up to four stops of shake correction, enhancing image quality throughout its zoom range. With a maximum magnification of 0.28x at the telephoto end, it excels in capturing detailed subjects.
The lens incorporates an inner focusing system and a stepping motor, allowing for high-speed autofocus, which is particularly beneficial for video shooting. The use of one UD and one PMO aspheric lens contributes to the overall optical quality, minimizing chromatic aberration and ensuring high resolution and contrast.
Overview of the VILTROX 35mm F1.7 E-Mount
The VILTROX 35mm F1.7 E-Mount lens is a prime lens priced at $179.00, making it about 45% cheaper than the Canon lens. Its large aperture of F1.7 allows for beautiful natural bokeh, making it an excellent choice for portrait and artistic photography. The lens features nine aperture blades that create a dreamy blur effect, effectively highlighting the subject in focus.
Designed for Sony E-Mount cameras, this lens boasts an optical structure of 11 elements in 9 groups, including specialized lenses that enhance image quality. The built-in STM stepping motor provides efficient and reliable autofocus, supporting advanced features like eye and face detection, which are essential for modern photography and videography.
Image Quality Comparison
When it comes to image quality, both lenses offer unique advantages. The Canon EF-S 18-135mm f/3.5-5.6 IS STM is equipped with advanced optical technology, including a refined Image Stabilization system and specialized elements that work together to minimize aberrations and distortion. This results in high-resolution images with excellent contrast.
In contrast, the VILTROX 35mm F1.7 excels in low-light conditions due to its larger aperture. This allows for more light to enter the lens, making it an ideal choice for capturing sharp images in darker environments. The artistic blur produced by the VILTROX lens can elevate the aesthetic quality of portraits and creative shots, providing a different but equally compelling image quality.
Autofocus and Performance
Autofocus performance varies significantly between the two lenses. The Canon EF-S 18-135mm includes a sophisticated inner focusing system and a stepping motor designed for fast and quiet autofocus, particularly useful for video shooting. This lens is optimized for continuous autofocus, making it suitable for dynamic scenes.
The VILTROX 35mm F1.7 also features a built-in STM motor that provides precise and efficient autofocus, with added support for eye and face detection. This feature is particularly beneficial for portrait photography, allowing for better focus tracking of subjects. While both lenses perform well, the Canon lens is slightly more versatile due to its zoom capabilities.
Convenience and Portability
The VILTROX 35mm F1.7 is notably lightweight at 170 grams, making it an excellent option for photographers who prioritize portability for impromptu shoots. Its compact design allows for easy handling and travel, making it a favorite for photographers on the go.
In contrast, the Canon EF-S 18-135mm weighs about 480 grams, which may be less convenient for extended use without support. However, the zoom range it offers provides greater versatility, allowing users to switch between wide-angle and telephoto without changing lenses. This added convenience can be advantageous in dynamic shooting environments.
Brand Reputation and Market Position
Canon is a well-established brand in the photography industry, known for its high-quality lenses and cameras. The Canon EF-S 18-135mm f/3.5-5.6 IS STM is designed for compatibility with a range of Canon DSLR cameras, making it a reliable choice for existing Canon users.
VILTROX, while less renowned than Canon, has been gaining traction with photographers seeking affordable and high-quality alternatives.

If you require a versatile zoom lens with advanced stabilization and excellent autofocus for both video and still photography, the Canon lens is the better option despite its higher price of $329.95.
However, if you prioritize a lightweight, compact design with a larger aperture for artistic effects and lower-light performance, the VILTROX lens at $179.00 offers significant savings and solid performance. Each lens has its strengths, making them suitable for different shooting styles and preferences.
