Discover the world's smallest and lightest ultra-wide-angle zoom lens designed for APS-C cameras. The Sigma 10-18mm f/2.8 DC DN Contemporary delivers exceptional versatility in a remarkably compact package, weighing just 250g with dimensions of 72.2 x 64.3mm. Its constant f/2.8 aperture across the entire focal range ensures outstanding low-light performance and smooth bokeh, whilst the 10-18mm range translates to an effective 15-27mm full-frame equivalent on Fujifilm X-mount bodies. Engineered with premium optics including aspherical elements and special low-dispersion glass, this lens produces razor-sharp images edge-to-edge whilst remaining incredibly portable. The lens mount features rubber sealing to protect against dust and moisture, making it ideal for travel, landscape, architectural, and video work. Supplied with a newly designed push-on petal-type lens hood, front and rear lens caps.
