Build Quality and Design

In terms of build quality, the Canon EF 50mm f/1.4 USM is constructed with a focus on portability and ease of use, featuring a compact design that weighs just 10.2 ounces. Its 58mm filter size is versatile for various photographic applications.

Both lenses are user-friendly, but the RF100-400mm's design caters specifically to those needing a longer zoom range without the bulk typically associated with telephoto lenses.

Optical Performance

The optical performance of the Canon EF 50mm f/1.4 USM is enhanced by its unique lens elements, including two high-refraction elements and Gaussian optics that minimize astigmatism. This lens excels in low-light conditions, producing clear and vibrant images. Meanwhile, the RF100-400mm F5.6-8 IS USM utilizes an Ultra Low Dispersion lens element to correct chromatic aberration, ensuring crisp and colorful images across its zoom range. While both lenses offer impressive optical quality, the choice between them largely depends on the shooting scenarios—standard vs. telephoto.

Autofocus Capabilities

When it comes to autofocus capabilities, both lenses are equipped with advanced technologies. The Canon EF 50mm f/1.4 USM features a fast and virtually silent ultrasonic motor, making it an excellent choice for still-life and portrait photography where quiet operation is crucial.
