The Tamron 11-20mm F/2.8 Di III-A2 RXD Lens for FUJIFILM X-mount APS-C mirrorless cameras offers an ultra-wide-angle zoom with a constant fast f/2.8 aperture, making it ideal for landscape, astrophotography, and architectural work. Its bright aperture allows enhanced low-light performance and control over depth of field. The lens boasts advanced optics, including XLD, LD, and glass-molded aspherical elements to minimize chromatic aberrations, distortion, and fringing, ensuring sharp, clear images with excellent color accuracy. Tamron's BBAR-G2 coating reduces flare and ghosting for improved contrast in challenging lighting. The RXD motor delivers smooth, silent autofocus, perfect for both stills and video, and with a minimum focusing distance of 5.9", this lens excels in wide-angle macro shots, making nearby subjects appear larger while creating soft bokeh effects. Built for tough environments, the lens features moisture-resistant construction and a fluorine coating on the front element to repel dust and dirt. A rounded seven-blade diaphragm further enhances its bokeh quality, making this lens a versatile choice for a wide range of shooting scenarios.
