Optical Performance Comparison
In optical performance, both lenses have competitive maximum apertures, with the Viltrox providing a marginal advantage at f/1.7 compared to the Canon's f/1.8. This difference allows the Viltrox to potentially gather slightly more light, which can be beneficial in challenging lighting conditions. However, the Canon lens is known for its sharpness and color accuracy, thanks to its Super Spectra coating. Both lenses aim to minimize flare and ghosting, but the Canon's reputation in this area might give it an edge for photographers looking for reliability in various shooting scenarios.
Autofocus Capabilities
When it comes to autofocus, both the Canon EF 50mm f/1.8 STM and the Viltrox 25mm F1.7 E utilize STM technology for quiet and efficient focusing.

The Viltrox lens also features quiet autofocus, along with face and eye recognition, which is particularly useful in portrait photography. This additional capability may appeal to videographers and portrait photographers who prioritize accurate focusing on subjects.
Weight and Portability
The Viltrox 25mm F1.7 E has a significant advantage in terms of weight, weighing only 170g, whereas the weight of the Canon lens is not specified but is generally heavier due to its construction. This makes the Viltrox more suitable for on-the-go photographers or those who prefer a lightweight kit for travel. If portability is a priority, the Viltrox could be the more appealing choice, especially for those who carry their gear for extended periods.
