HD PENTAX-DA 18-50mm F4-5.6 DC WR RE er konstruert for PENTAX DSLR kameraer med PENTAX K-fatning. Dette standard zoomobjektivet med sammenfoldbar mekanisme er nykonstruert, kompakt og lett, i værsikret utførelse for bruk under alle værforhold.
Dette standard zoomobjektivet er utviklet for enkel bruk med høyoppløste DSLR systemkameraer. Takket være det sammenfoldbare mekaniske systemet, er dette objektivet det korteste standard zoomobjektivet på markedet*, kun 41mm i sammenfoldet posisjon. PENTAX originale HD coating sørger for superlav dispersjon, og asfæriske elementer kompenserer effektivt for varierende forvregning. Objektivet leverer skarpe, kontrastrike, velbalanserte bilder. Den innebygde DC motoren gir myk, stillegående autofokus, og den værsikrede konstruksjonen gir ekstrem pålitelighet og solide egenskaper under krevende forhold utendørs.

An interchangeable zoom lens, featuring a new retractable mechanism creating the world’s shortest length
This standard zoom lens has been developed as a compact, easy-to-use everyday lens that meets user demand for a downsized, high-resolution digital SLR imaging system. Thanks to its retractable mechanism — employed for the first time in the PENTAX K-mount lens system — it provides the world’s shortest length in the stored position: just 41 millimeters. * Despite its ultra-compact design that assures outstanding portability, it also features the PENTAX-original HD Coating, Anomalous Dispersion Glass elements and aspherical elements to effectively compensate various aberrations for sharp, high-contrast, well-balanced images.
Note: In the case of use with the models below, when the lens is retracted, the display indicating lens retraction is not shown and photographs can be taken. For the K-3 and K-S1, a firmware upgrade is necessary.

The world’s shortest standard zoom lens
The world’s shortest standard zoom lens
This standard zoom lens offers a zoom ratio of approximately 2.8 times to cover the wide-angle to standard ranges (for focal lengths equivalent to 27.5mm to 76.5mm in the 35mm format), which are the most frequently used ranges in general photographic applications. Thanks to its new retractable mechanism, it measures a mere 41millimeters in length in the stored position — the world’s shortest for a standard zoom lens — to assure outstanding portability in combination with today’s downsized digital SLR camera body.
Dependable weather-resistant construction
This lens features a dependable weather-resistant construction with nine special seals to effectively prevent the intrusion of water into the interior. By pairing it with a weather-resistant PENTAX digital SLR camera body, the user is assured of a durable, reliable digital imaging system that performs superbly in demanding shooting settings — even in the rain or mist, or at locations prone to water splashes or spray.
