The Canon RF100-400mm F5.6-8 is USM is priced at $699.00, while the VILTROX 15mm F1.7 E-Mount Lens for Sony is significantly cheaper at $239.00.

When considering budget constraints, the lower price of the VILTROX lens may appeal to photographers looking for quality without breaking the bank. However, the Canon lens offers a versatile zoom range that may justify its higher price for those who need greater focal length and advanced features.

In contrast, the VILTROX 15mm F1.7 offers an 84.9° wide angle of view, making it suitable for landscapes and indoor photography. However, while it excels in producing a dreamy background blur thanks to its large aperture, it may not achieve the same level of detail in distant subjects as the Canon lens.

Autofocus Capabilities

The Canon RF100-400mm features high-speed, smooth, and quiet autofocus powered by Nano USM technology, making it ideal for capturing fast-moving subjects like wildlife or sports. On the other hand, the VILTROX 15mm F1.7 is equipped with an STM motor that enables precise and fast automatic focusing, which is particularly beneficial for portrait photography and VLOGs.
