Fujifilm is following its plan to expand the XF camera system with high-quality lenses. Recently, the wide-angle zoom XF 10-24 mm was added. This lens will please especially landscape and architectural photographers. The widest aperture (f/4) is constant along the zoom range and adequate for typical applications of a wide-angle lens. The smallest aperture (f/22) will provide great depth-of-field without showing too much diffraction softness. The zoom ring has no marking for 16 mm (24 mm full-frame equivalent) but carries one for 20 mm (30 mm ffe), which is a little odd. Built quality is good and the lens feels solid. All rings operate smoothly without shaking. However, except for some parts (like the camera flange) this lens is mostly not made of metal. The provided lens hood is also plastic but feels sturdy and is nicely shaped. The front element and the filter thread do not rotate when zooming or focusing, which is important for a wide-angle lens that is often used together with a polarizer filter. Zooming and focusing are both performed mostly internally and so the lens never changes its size or shape (you can see some movement of the front element when zooming but the filter thread remains fixed).……..
