Experience Using the Product

During testing, the Fujifilm XF 100-400mm lens performed admirably in various scenarios. In wildlife photography, the lens’s impressive reach allowed for capturing detailed images of birds and other animals from a distance. The autofocus system was quick and accurate, making it easy to track moving subjects. The image stabilization technology proved effective, allowing for handheld shooting at slower shutter speeds, which is crucial for longer focal lengths.

In landscape photography, the lens delivered stunning detail and clarity, especially when stopped down to f/8 or f/11. The color rendition was rich and vibrant, showcasing Fujifilm’s renowned film simulation profiles beautifully. However, in low light conditions, the maximum aperture of f/4.5 to f/5.6 may limit performance, requiring higher ISO settings or careful consideration of lighting.

Moreover, the weather-resistant feature was a significant advantage during outdoor shoots in less-than-ideal conditions, providing peace of mind against moisture and dust.
