Review Summary

The Sigma 10-18 f/2.8 C Ultra-Wide lens (X mount) is a small, lightweight lens that is optically superb on a Fujifilm X-H2 camera. It is very well made, and quite sharp virtually edge to edge. The push-on lens hood is unobtrusive and sturdy. I highly recommend this lens!

By utilizing unique optics which have been designed to correct lens aberrations, the SIGMA 10-18mm F2.8 DC DN | Contemporary produces images that are sharp across the entire image.
The use of an aspherical lens with large eccentricity and refractive index as the first lens element has enabled a lens construction with a reduced number of elements. Used in conjunction with multiple aspherical lenses and special low-dispersion glass, the lens can produce high resolution images whilst remaining compact and lightweight.

Create expressive close-up images using the 11.6cm minimum focusing distance when shooting at 10mm. With a magnification ratio of 1:4, the lens captures unique portraits, still life and more.

The SIGMA 10-18mm F2.8 DC DN | Contemporary is the world's smallest and lightest ultra-wide angle zoom lens for APS-C cameras, with a length of 62.0mm, a maximum diameter of 72.2mm, and a weight of 260g. The lens can be carried around with ease or attached to an APS-C mirrorless camera and a gimbal to create an ultra-portable video setup.

A newly developed push-on petal type hood is included with the lens. Unlike the conventional bayonet type lens hoods that attach with a rotating movement, this push-on type lens hood is attached onto the lens using a spring and lever system. The implementation of this new design reduces the size and thickness of the hood so that it matches the compact size of the lens.

With ultra-wide focal length, portable body and razor-sharp optics, the SIGMA 10-18mm F2.8 DC DN | Contemporary is the perfect portable option for landscape, travel, interior and street photography. It also boasts impressive video capability owing to its bright F2.8 aperture, which makes it well-suited to shooting in low-light environments and creating a shallow depth-of-field. The ultra-wide angle-of-view is ideal for hand-held vlogging that requires the capture of both the subject and the environment.
The lens has been designed to suppress focus breathing. The change in angle-of-view due to focus shift is minimized, creating a natural-looking focus shift when recording video.

The lens is compatible with the electronic image stabilization function, aberration correction function, DMF, and AF+MF in camera bodies from various manufacturers. The advantage using this ultra-wide-angle lens is that it provides a generous angle-of-view even when the electronic image stabilization function crops the image.
*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
