  "account": "Fujifilm has unveiled the Fujinon XF400mm F4.5 R LM OIS WR lens for its X series of mirrorless cameras. This lens, which is equivalent to 600mm in 35mm, boasts a bright f/4.5 maximum aperture. Remarkably lightweight at just 1,245g (excluding lens hood and cap), it is perfect for handheld shooting of distant subjects like wildlife, sports and action. The lens features enhanced shake detection and an optimised stabilisation mechanism that delivers up to 5.5 stops of image stabilisation.\n\nUsing the Fujinon Teleconverter XF1.4X TC WR boosts the focal length to 560mm, improving to 800mm or 1,200mm equivalent with the Fujinon Teleconverter XF2X TC WR. Despite its long focal length, the 400mm lens is surprisingly compact. In terms of construction, the lens has a 21-element, 14-group configuration with 2 Super ED elements and 4 ED elements, aimed at minimising chromatic aberration.\n\nThe reviewer had the opportunity to test the lens pre-release while photographing birds of prey. Although it was raining during the session, the photographer noted that the lens performed well under such conditions. Despite its huge focal length, the 400mm lens is surprisingly light and balanced, offering a centre of gravity closer to the camera body. It comes with a lens foot to help with the feeling of fatigue while holding it steady for long periods. The XF400mm can be used handheld surprisingly well, even in challenging weather conditions. The lens has 20 sealed points for both dust and water resistance, with a fluorine coating on the front lens element to prevent water and smudges. In tests, the stabilisation systems helped keep shake minimal.",
