HD PENTAX-DA FISH-EYE 10-17mm
f3.5-4.5 ED (APS-C) (Fullformat)
HD PENTAX-DA FISH-EYE10-17mmF3.5-4.5ED
Når objektivet er montert på et Pentax K-1 eller Pentax K-1 II, kan du bruke dette objektivet hvis du fjerner solblenderen.
Designet for bruk med digitale Pentax kameraer med K-fatning. Dette objektivet gir et zoomområde fra fiskeøye til ultra-vidvinkel. Kan også brukes på kameraer med fullformat sensor.
Utviklingen av dette nye objektivet tar utgangspunkt i den nåværende modellen, SMC Pentax DA Fish-Eye 10-17mm F 3.5-4.5 ED (IF), men er en omfattende videreutvikling. En ny flerlags HD-antireflekscoating er benyttet for å sikre høy kontrast og skarphet uten reflekser. Også det utvendige har fått en reell ansiktsløftning for å matche designen til de nyeste DSLR modellene. En stor forskjell er også at solblenderen kan tas av.
HD coating for forbedret bildekvalitet
Med Pentax nyeste multi-lags coating, er reflekser redusert mer enn 50 prosent i forhold til tidligere. Objektivet har også en forbedret lystransmisjon og ED-linse for å minimere kromatisk aberrasjon.
* HD er en forkortelse for High Definition.
Fish-Eye zoomområde
På 10mm brennvidde gir objektivet en 180 graders bildevinkel når det brukes på et kamera med APS-C sensor. En flott brennvidde for å skape dramatiske bilder som virkelig skiller seg ut i mengden. Siden bildevinkelen endres dramatisk ved zooming, har fotografen store kreative muligheter. Hvis du liker spennende synsvinkler, er det vanskelig å finne et morsommere objektiv.
Design
Objektivet har en helt ny design og finish, tilsvarende de siste DA og D-FA objektivene. Dette betyr at den også matcher de nyeste kameramodellene. Den avtakbare solblenderen gir et rundt fiskeøye- bilde * når objektivet er montert på en modell med fullformatsensor.
* Uten linsedeksel, med "crop-funksjon" satt til "FF-modus", kan vignettering forekomme, samt lavere bildekvalitet i kantene, da bildet inneholder elementer utenfor objektivets bildesirkel.
SP coating på frontelementet
Frontelementet er utstyrt med SP (Super Protect) coating, som effektivt avviser vann, fett og skitt. Dette gjør det svært enkelt å rengjøre.
Andre funksjoner
Quick-Shift fokus systemet gjør det mulig å raskt skifte fra autofokus til manuell fokus.
En fokuseringsavstand på bare 14cm gjør at frontelementet kan plasseres bare 2,5cm fra
motivet, for ekstreme nærbilder.

Featuring the latest HD Coating to further upgrade image quality, and a totally redesigned body
The development of this new zoom lens was based on smc PENTAX-DA FISH-EYE10-17mmF3.5-4.5ED, while conducting a thorough review of lens coatings. The high-grade, multi-layer HD Coating has been applied to the optical elements for high-contrast images with edge-to-edge sharpness and free of flare and ghost images. The exterior has been totally redesigned to match the design of the latest PENTAX K-mount digital SLR models, and also to make its lens hood removable.
When mounted on a PENTAX K-1 or PENTAX K-1 Mark II camera body, the photographer can remove the lens hood to produce nearly circular fish-eye images.

HD Coating to enhance imaging power
After a thorough review of lens coatings, PENTAX applied HD Coating* — PENTAX’s latest multi-layer coating — to the lens. Compared to conventional multi-layer coatings, this high-performance, multi-layer coating reduces average reflectance in the visible light range by more than 50 percent and improves light transmittance, to minimize the adverse effects of flare and ghost images even in demanding lighting conditions such as backlighting. This zoom lens also incorporates an Extra-low Dispersion (ED) glass element to effectively compensate for chromatic aberration for extra-clear, high-contrast images.
* HD is the abbreviation of High Definition.
Zoom range covering the fish-eye angle
When mounted on a PENTAX digital SLR camera body, this zoom lens provides a 180-degree diagonal angle of view in the APS-C format at a focal length of 10mm to deliver eye-catching fish-eye images. Since the angle of view shifts dramatically with a slight change of focal length, the photographer can easily create visual expressions typical of an ultra-wide-angle lens, such as exaggerated perspective, deformed subjects and a pan-focus effect to capture the entire image field in focus.
New exterior design to match latest digital SLR models
While retaining the overall size of the original smc PENTAX-DA FISH-EYE10-17mmF3.5-4.5ED, this zoom lens features a totally new exterior design, similar to that of the latest DA- and D FA-series lenses. This new appearance also makes it a perfect partner for the newest K-series digital SLR models. Although it is an ultra-wide-angle zoom lens, it has been designed to be extremely compact and lightweight. The removeable lens hood allows for nearly circular fish-eye images* to expand the range of photographic expressions, when mounted on a PENTAX K-1 or PENTAX K-1 Mark II camera body.
* When the lens hood is removed with the Crop Function set to FF mode, there may be vignetting and/or lowered imaging performance at the edges of the image field, because the resulting image contains elements outside the lens’s image circle.
SP Coating to repel stains SP (Super Protect) Coating, highly repellent to water, grease and dirt, has been applied to the lens’s front surface using a PENTAX-exclusive fluorine deposition process, making it easy to wipe off any stains such as fingerprints. This frees the photographer from worries in outdoor photography.
Other features I. Quick-Shift Focus System, to provide instant shift to manual-focus operation after locking the subject in focus during AF operation by pressing the shutter-release button halfway down; usable at any time during AF operation
II. A minimum focusing distance of 14 centimeters, allowing the photographer to move in as close as approximately 2.5 centimeters from the front end of the lens to the subject, for ultra-close-up photography
