Overview

The Canon RF 75-300mm f/4-5.6 is an entry-level telephoto zoom based on an old optical design, resulting in soft image quality and strong color fringing at the long end. Its slow, noisy DC AF motor and restricted focus area limit performance, and manual focus causes extension and front element rotation. However, it is lightweight and affordable, making it suitable for budget-constrained users or high-risk scenarios like use by children. It covers a useful 75-300mm range for portraits, sports, and general telephoto needs.
