Overview

The Canon RF-S 18-45mm f/4.5-6.3 IS STM is a compact, lightweight kit lens for APS-C EOS R cameras. Optically, it delivers good sharpness, especially in the center, and produces detailed images in good light. However, it has a slow maximum aperture and a limited 2.5x zoom range, with the wide end starting at 18mm (29mm equivalent) rather than a wider angle. Build quality is typical for a kit lens: plastic construction but lightweight at 125g. Handling is aided by effective lens-based image stabilization, beneficial for cameras without IBIS. Autofocus is quick and quiet thanks to STM. This lens suits budget-conscious beginners or those wanting a small, affordable walk-around zoom for casual photography in good lighting.
