Ricoh Imaging | Pentax smc DA 18-270mm f/3.5-6.3 SDM Lens
This high-magnification zoom lens offers 15X zoom ratio to cover focal lengths from 27.5mm wide angle to 414mm super telephoto in the 35mm format, while its built-in supersonic AF driving mechanism achieves both smooth, quiet AF operation and a compact, lightweight body. This lens incorporates two extra-low dispersion (ED) elements in its optics, delivering bright, high-resolution images even at the edges. It is designed with rounded diaphragm blades to produce a smooth, beautiful bokeh (out-of-focus rendition), while minimizing the streaking effect of point light sources. The wide-angle-to-long-telephoto zoom coverage makes this zoom lens extremely versatile and handy, allowing the user to effortlessly capture a wide variety of subjects, ranging from landscapes and snapshots to sports events, without the need to change lenses.
