Design and Build Quality

In terms of design, the Viltrox 25mm F1.7 E weighs only 170 grams, which makes it highly portable and suitable for travel and everyday use. This lightweight design does not compromise the lens's functionality, providing a good balance between sturdiness and ease of handling.

Both lenses are made for comfortable handling, yet the Viltrox's weight advantage is notable for those on the go.

Aperture and Low-Light Performance

The Viltrox 25mm F1.7 E features a bright maximum aperture of f/1.7, which excels in low-light conditions and offers great control over depth of field. On the contrary, the Yongnuo YN50mm F1.8C has a slightly larger aperture at f/1.8, which also benefits low-light photography and provides sharp images. While both lenses perform well in dim settings, the Viltrox's f/1.7 aperture provides a marginally better advantage in controlling depth of field, making it ideal for portraiture and creative photography.

Autofocus Capabilities

Autofocus performance is essential for any modern lens, and both the Viltrox 25mm F1.7 E and the Yongnuo YN50mm F1.8C feature autofocus systems. The Viltrox uses an STM stepper motor, which provides a quiet autofocus experience, minimizing disruption during photo and video shooting. The Yongnuo, on the other hand, supports both autofocus and manual focus, making it versatile for various shooting styles. While both lenses excel in autofocus, the Viltrox's quieter operation may be preferable for videographers.

Compatibility and Versatility

The Viltrox 25mm F1.7 E is specifically designed for Sony E-mount cameras, such as the ZV-E10 II and a6700, allowing seamless integration with these devices. The Yongnuo YN50mm F1.8C is compatible with a range of Canon EF mount cameras, including popular models like the 5D and 7D, making it a versatile choice for Canon users. Therefore, the choice between these two lenses will largely depend on the camera system you own.

Image Quality

Both lenses promise good image quality, but their unique designs cater to slightly different photographic styles. The Viltrox 25mm F1.7 E’s f/1.7 aperture offers superior depth of field control, making it advantageous for portrait photography. The Yongnuo YN50mm F1.8C, with its f/1.8 aperture, provides excellent edge-to-edge sharpness, which is beneficial for landscape photography. Depending on your photography preference, either lens could serve you well.

This makes the Yongnuo about 25% cheaper, which may appeal to budget-conscious photographers. However, the additional features and performance of the Viltrox may justify its higher price for some users.

Which should you buy?

Choosing between the Viltrox 25mm F1.7 E and the Yongnuo YN50mm F1.8C ultimately depends on your specific needs and camera system. If you own a Sony E-mount camera and prioritize features like low-light performance and quiet autofocus, the Viltrox is the better choice.
