Description — Pentax 18-270mm f/3.5-6.3 ED SDM
The Pentax SMC DA 18-270mm f/3.5-6.3 is a Zoom lens designed for APS-C format Pentax K mount DSLR cameras. It covers a focal length range from 18mm to 270mm, spanning wide-angle through super-telephoto reach in a single package. The maximum aperture opens to f/3.5 at the wide end.
Autofocus is supported, with both Auto and Manual focus modes available to suit different shooting preferences. The lens accepts 62mm filters and has a total weight of 453g, keeping it manageable for an all-in-one zoom. One notable consideration is that this lens carries no image stabilization, so photographers shooting handheld at longer focal lengths should account for potential camera shake.
It is exclusively designed for APS-C sensor bodies within the Pentax K-mount ecosystem.
