The lens also includes optical image stabilisation with up to 5.5 stops for handheld shooting.
Who It Is Best For
This lens suits photographers who want long reach without carrying larger telephoto equipment. It is a practical choice for people who shoot outdoors, travel often, or spend time walking with a camera and want a lens that stays manageable.
What To Know Before You Buy
The variable maximum aperture means it is not the same as a faster professional telephoto lens, so it is worth checking whether the available light and your shooting style fit what you need. It is built for reach and portability rather than the brightest aperture.
Pros: Long telephoto reach in a lens that is easier to carry, with optical image stabilisation that supports handheld shooting.
Cons: The variable aperture means less light at the long end than a faster telephoto lens.
