Covering an extremely useful range from wide‑angle to short telephoto, it serves as an excellent all‑purpose lens for travel, landscapes, portraits and close‑up work. The bright f\/2.8–4 aperture range offers better low‑light performance than most kit lenses, while Sigma’s HSM motor provides fast, quiet autofocus on compatible Pentax bodies. The lens also features a close‑focus “macro” capability, allowing detailed shots at short working distances.\u003c\/p\u003e\n\u003cp\u003eThis model is well regarded for its balance of image quality, portability and flexibility, making it a strong upgrade from standard kit zooms.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCondition\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eOverall Condition: Very Good\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLight cosmetic wear consistent with normal use.\u003c\/li\u003e\n\u003cli\u003eAutofocus operates correctly on Pentax K‑mount AF bodies.\u003c\/li\u003e\n\u003cli\u003eZoom and focus rings move smoothly with no stiffness.\u003c\/li\u003e\n\u003cli\u003eAperture blades are clean and responsive.\u003c\/li\u003e\n\u003cli\u003eOptics present well with typical minor dust only.\u003c\/li\u003e\n\u003cli\u003eA clean, reliable example of this popular Sigma all‑rounder.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eIncluded\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSigma 17–70mm f\/2.8–4 DC Macro HSM Lens (Pentax K)\u003c\/li\u003e\n\u003cli\u003eFront Cap\u003c\/li\u003e\n\u003cli\u003eRear Cap\u003c\/li\u003e\n\u003cli\u003eHood\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eCollector \u0026amp; User Notes\u003c\/h2\u003e\n\u003cp\u003eThis lens is part of Sigma’s DC series, designed specifically for APS‑C digital cameras.
