Design and Build Quality
The Canon RF15-35mm features a robust design with weather-sealing to protect against dust and moisture, making it reliable for outdoor shooting. The lens is compact and lightweight, designed for comfortable handling during extended periods. On the other hand, the Sony FE 400-800mm boasts an internal zoom design, which enhances stability while shooting, reducing the center-of-gravity shift.

Image Quality
In terms of image quality, the Canon RF15-35mm is equipped with a bright f/2.8 maximum aperture, offering high image quality and excellent performance in low-light conditions. Its optical image stabilization allows for up to five stops of shake correction, which is crucial for handheld shooting. Conversely, the Sony FE 400-800mm delivers high resolution and natural bokeh throughout its zoom range. The choice between these lenses largely depends on your focus: Canon excels in wide-angle clarity and low-light performance, while Sony shines with its telephoto capabilities and bokeh quality.
Autofocus Performance
The Canon RF15-35mm utilizes Nano USM technology for fast, smooth, and quiet autofocus, making it ideal for capturing spontaneous moments without disturbing the environment. The minimum focusing distance of 0.92 ft. allows for versatility in close-up shots.
