Product Gallery
Product Overview
Pentax HD Pentax-DA* 11-18mm F2.8 is an ultra wide-angle zoom lens for Pentax K-mount. It covers the APS-C image circle. Introduced by Pentax in 2017, it has .
Like most zoom lenses, the HD Pentax-DA* 11-18mm F2.8 is externally-zooming.
The f/2.8 maximum aperture is quite bright for an ultra wide-angle zoom lens and can be quite valuable for night photography. During daytime, it can offer a unique perspective for landscape photography as well. Even though the lens is not stabilized, at this focal range it does not usually matter. In fact, some may be able to get cleaner corners without image stabilization.
Some photographers may be disappointed by the fact that the lens does not accept front screw-on filters.
