Introduction

Product Description The RF10-20mm F4 L IS STM is the world's first 10mm ultra-wide-angle full-frame autofocus lens1. In addition to providing an ultra-wide-angle zoom range of 10mm-20mm, it maintains a compact lens design, measuring only approximately 112 mm in length and weighing just approximately 570 g. The lens features a built-in optical image stabilizer, providing 5 stops of image stabilization2. It also introduces Peripheral Coordinated Control for the first time4. When used together with in-body image stabilization, it effectively corrects peripheral shake blur that commonly occurs with wide-angle lenses, delivering higher image quality across the edges of photos. It can also reduce slight peripheral image shake when shooting videos5.
