It delivers superb sharpness, robust build quality, and a quiet, reliable HSM autofocus system within a compact, inner-focusing design. Drawbacks include the inability to use screw-on filters due to a bulbous front element, which is also highly susceptible to smudges. Additionally, the lens has a slow variable aperture (f/4.5-5.6) and suffers from a minor compatibility issue on Pentax bodies that results in missing focal length EXIF data between 8mm and 10mm.

The Sigma AF 8-16mm f/4.5-5.6 DC HSM is an extreme, rectilinear ultra-wide zoom lens designed specifically for APS-C format cameras, providing a full-frame equivalent field of view of roughly 13-26mm. A major technological highlight of this lens is the inclusion of four innovative FLD glass elements, which mimic the properties of expensive fluorite glass to aggressively correct color aberrations. The lens boasts a very high build quality made of tightly assembled metal parts, features a hypersonic AF motor (HSM) that ensures fast and nearly silent autofocusing, and maintains a constant physical length during zooming and focusing. However, the lens's extreme design introduces several notable compromises. A prominent drawback is the "bulb"-like protruding front element which prevents the use of standard front-mounted filters and leaves the glass somewhat vulnerable, though it is partially shielded by a fixed petal-shaped hood. Additionally, the dedicated lens cap requires an extra attachment tube that causes severe edge shading if left on during shooting, even at the 16mm setting. The lens is also unusually elongated for an ultra-wide zoom—measuring over 10cm in length—and exhibits only average...
