Ultra-wide and stabilized, the Canon RF 14-35mm f/4 L IS USM is a uniquely versatile zoom characterize by its broad range, constant f/4 maximum aperture, and advanced optical design. Gaining a bit on the wide end, this zoom offers a broader field of view to suit landscape, nature, and architectural applications, and its modest maximum aperture also contributes to a sleek, highly portable design for walkaround shooting.

In terms of optics, the lens is befitting of its L-series designation and features three aspherical elements and three UD elements that produce a highly corrected image with high sharpness and accurate color rendering. A trio of unique coatings have also been applied to suppress flare and ghosting throughout the zoom rang. The L-series designation is also indicative of a robust physical design, and this 14-35mm is weather-sealed and features a fluorine coating on the exposed elements for further protection against trying weather conditions.

Unique among ultra-wides, this lens is also distinguished by its Optical Image Stabilizer that compensates for up to 5.5 stops of camera shake, or up to 7 stops when paired with cameras featuring IBIS. Additionally, there is also an apt Nano USM that yields fast and quiet autofocus performance and there is a minimum focusing distance of just 7.9″ throughout the entire zoom range for creative wide-angle close-up shooting.
