The handling of the lens is further improved by its small and lightweight construction, which also reduces the amount of tiredness experienced during lengthy shooting sessions. When using a tripod for photography, the installation of a tripod collar gives additional stability and support for the camera. The XF 100-400mm lens, in general, features an ergonomic design that makes taking pictures with it a more pleasurable experience for photographers.

Image Stabilization

The XF 100-400mm lens has efficient optical image stabilization (OIS) technology built into it, which helps to mitigate the negative effects of camera shake to a large extent. Even while shooting handheld, optical image stabilization technology (OIS) prevents blurry photos by correcting for both angle and shift motions that may occur.

While photographing in low-light circumstances or while utilizing a longer lens length, this function is especially helpful. Because of the image stabilization capabilities of the lens, photographers are able to take handheld photos with longer exposures without compromising image quality. It enables photographers to take clear photos even in adverse lighting settings or when utilizing slower shutter speeds, which boosts the lens’ adaptability in a variety of shooting situations.
