Compact and lightweight RF-S ultra-wide-angle zoom lens equipped with anti-shake function This is the first ultra-wide-angle zoom lens in the RF-S series of lenses. This RF-S ultra-wide-angle lens has a focal length of 10-18mm, equivalent to a viewing angle of approximately 16-29mm*1, and can capture impactful ultra-wide-angle images. The lens design is very compact, very similar to the kit lens RF-S18-45mm F4.5-6.3 IS STM in body shape, and weighs only about 150 grams. Although it is an ultra-wide-angle zoom lens, it is also equipped with optical image stabilization and supports collaborative image stabilization, making it clear and stable even if you are holding it while walking. It is very convenient to use for landscape, travel, daily street photography, Vlog, live broadcast, or shooting with drone or stabilizer. It is a lens worth buying in addition to the kit lens.
