| dbo:abstract | Die Pentax K-3 II ist eine APS-C digitale Spiegelreflexkamera, die vom japanischen Hersteller Ricoh unter der Marke Pentax vertrieben wird. Sie wurde am 23. April 2015 als neues Spitzenmodell vorgestellt und ist seit dem 1. Juni 2015 in Deutschland im Handel. Von der Vorgängerin Pentax K-3 unterscheidet sie sich insbesondere durch ein integriertes GPS-Modul mit Astrotracer-Funktion (automatischer Verfolgung des Sternenhimmels durch Sensorshift für scharfe Himmelsfotografie bei Nacht) und die „Pixel Shift Resolution“-Funktion, die eine höhere Auflösung bei gleicher Pixelzahl ermöglicht. Das integrierte GPS Modul zeichnet auch die Positionen der Kamera in einer Log-Funktion auf und nicht nur bei einer Aufnahme. Durch die Integration des GPS-Moduls ist der eingebaute Blitz weggefallen. Bei der „Pixel Shift Resolution“-Funktion werden vier in schneller Folge aufgenommene Einzelbilder automatisch kombiniert, wobei dazu der Sensor jeweils um 1 Pixel (etwa 4 µm) bewegt wird. Das führt dazu, dass alle 4 Farben (2 * Grün, 1 * Rot und 1 * Blau) des Bayer-Patterns an derselben Stelle aufgezeichnet werden. Damit wird für jedes Pixel das gesamte Farbspektrum aufgezeichnet. Das Ergebnis davon ist eine genauere Farbwiedergabe für jedes Pixel und eine höhere Auflösung. Die Bilder können sowohl als JPEG als auch als RAW-Dateien gespeichert werden. In dieser RAW-Datei sind die 4 Einzelaufnahmen vorhanden. Zurzeit können diese Raw-Dateien nur von dem Pentax eigenen Raw-Entwickler (DCU) und einer Modifikation von DCRaw entwickelt werden, die anderen großen Hersteller von Rawentwicklern können das Format derzeit noch nicht verarbeiten. Das Verfahren eignet sich aber nur für statische Motive, da von der ersten bis zur letzten Belichtung etwa 1,3 Sekunden verstreichen. Außerdem sollte die Kamera auf einem stabilen Stativ stehen. Des Weiteren wurde nach Herstellerangaben der Bildstabilisator nach -Standard von 3,5 auf 4,5 Lichtwerte verbessert und das Autofokusmodul optimiert. (de) La Pentax K-3 II es una cámara réflex digital que se presentó el 22 de abril de 2015 como la sucesora de la exitosa cámara Pentax K-3. La K-3 II incorpora un nuevo sistema que le permite obtener imágenes con mayor cantidad de detalle y precisión de color. La anterior k3, y cualquier cámara reflex con sensor CMOS, para generar la imagen final, se hace sobre la base de la interpolación de 3 imágenes (rojo verde y azul). Por ejemplo, la K-3, la imagen final de 24Mpx, se crea a partir de 3 imágenes roja verde y azul de 6Mpx cada una. Una vez combinadas, se obtiene la imagen final de 24Mpx. El nuevo sistema de la Pentax K-3 II, permite mediante el desplazamiento del sensor en 4 direcciones, la distancia de 1 pixel, tomar 4 capturas simultáneas, de forma que se obtiene una imagen completa de 24Mpx de cada canal de color rojo verde y azul.De esa forma se evita tener que realizar interpolación de pixeles, pudiendo generar una imagen final con una gran nivel de detalle, sin moaré de color, ni artefactos de colores, ni colores falsos que en ocasiones se producen en cámaras con sensor CMOS, con patrón Bayer (el sistema que tienen todos los sensores cmos). El sensor cámara es un dispositivo CMOS APS-C con una resolución efectiva de 24,35 megapíxeles con el procesador de imágenes Prime III que comparte con la Pentax 645Z. Otra de sus características es la incorporación de un módulo GPS y módulo astrotracer, permitiendo localizar las fotos de manera automática, y hacer seguimiento de las estrellas en tomas nocturnas, mediante la información conjunta del GPS, sensores de posición, brújula, etc.Esta función permite tomas de larga exposición, de tomas nocturnas de cielo, evitando que salgan las rastros o líneas del movimiento de las estrellas, permitiendo capturas que con otras cámaras solo son posibles utilizando rótulas con monturas ecuatorial motorizada. Para la incorporación de los módulos anteriormente descritos se ha prescindido del flash de la cámara. (es) The Pentax K-3 II was a flagship APS-C DSLR camera announced by Ricoh on April 23, 2015. It is differentiated from its predecessor by inclusion of a GPS module with AstroTracer functionality (automatic tracking of the passage of stars across the sky, i.e. compensation of the rotation of the Earth; allows sharper, more detailed (less noisy) astrophotographs from longer exposures) and by "Pixel Shift Resolution", a capture mode giving higher spatial resolution. The integrated GPS module can also record positions of the camera while not in use, which allows subsequently reconstructing the path taken by the photographer. The GPS module occupies the space formerly given to the onboard flash, which has been omitted. Pixel Shift Resolution records four separate images in quick succession and combines them into a final image. The higher spatial resolution results from the fact that the sensor is shifted by one pixel between each pair of sequential exposures, such that all four colour filters in the Bayer pattern are applied once for each pixel (two green, one red, one blue). Therefore, the full colour spectrum is available for each pixel, giving more accurate (non-interpolated) colour and higher resolution. Pixel Shift images can be saved as JPEG or RAW, as can normal images. A Pixel Shift RAW file contains embedded in it the original four captures in RAW format. This capture mode is best used for static subjects, as approximately 1.3 seconds pass between the first and last exposure. This also dictates use of a tripod or other stabilisation for the camera. Of further note is the image stabilisation system, which according to CIPA standard has been improved from 3.5 to 4.5 stops in effectiveness since the K-3. The manufacturer further states that autofocus has been improved. (en) «Pentax К-3 II» (яп. ペンタックスK-3 II) — цифровой зеркальный фотоаппарат марки «Пентакс», дальнейшее развитие модели K-3.

Помимо функции Pixel Shift Resolution новая модель отличается от К-3 наличием встроенного GPS-приёмника, отсутствием встроенной вспышки и усовершенствованной системой стабилизации с эффективностью 4,5 ступени экспозиции по методике CIPA. Фотоаппарат представлен 22 апреля 2015 года. Поступил в продажу 28 мая 2015 года, стоимость в США составила 1097 долларов, однако примерно через месяц снизилась до 935 долларов.
