After years of production and numerous announcements and teases, Ricoh finally produced and launched its new flagship, the first Pentax full-frame DSLR camera Pentax K-1, which came along with two lenses - Pentax-D HD FA 15-30mm f/2.8 ED SDM WR and Pentax-D HD FA 28-105mm f/3.5-5.6 ED DC WR.
The Pentax K-1 represents the first full-frame (35mm) from the Pentax family (the first to arrive at the market, to be more precise) and it sets new standards in its series thanks to its performances. It is equipped with a 36.4MP CMOS sensor, a new PRIME IV processor, SAFOX 12 autofocus system with 33 AF points (25 of which are cross-type), a new generation 5-axis sensor-shift image stabilization (Shake Reduction II (SR II)), 4.4 fps continuous shooting (17 RAW and 70 images in the JPEG format), a new optical viewfinder (pentaprism) with the coverage of "nearly 100%", as Ricoh states, and 0.7x magnification, a tiling 3.2" 1,037,000-dot TFT LCD screen (that rotates horizontally, vertically, and diagonally, while at the same time being in alignment with the lens axis), while the video is Full HD at 30 fps.
The sensor of the new Pentax K-1 does not feature the classic AA (Anti-Aliasing) filter, yet, like the Pentax K-3 II, the K-1 offers some type of simulation of the AA filter by applying microscopic vibrations to the image sensor, which neutralizes moire. Moreover, the new DSLR's sensor can move in all directions thanks to Ricoh's new Pixel Shift Resolution system. This mechanism does not increase linear resolution of the sensor, but like in the case of the said K-3 II, it moves the sensor with slight movements in order to capture every bit of information at each pixel (four images of the same scene are captured by shifting the image sensor by a single pixel for each image, and then they are synthesized into a single composite image). This system also provides a new motion correction function, which automatically detects a moving object during continuous shooting.
What is important for owners of Pentax APS-C is that the new K-1 features a crop mode, which offers settings in-camera for APS-C shooting, so those Pentax APS-C lenses will not remain unused. Other significant properties of the new Pentax K-1 are the following: it boasts a magnesium-alloy construction with the inclusion of as many as 87 sealing parts, which makes it dustproof, weather-resistant and cold-resistant; it also features Wi-Fi support, GPS, as well as an electronic compass.
Along with the first full-frame DSLR, Ricoh introduced two lenses aimed at 35mm sensors - Pentax-D HD FA 15-30mm f/2.8 ED SDM WR and Pentax-D HD FA 28-105mm f/3.5-5.6 ED DC WR - which are perfect to combine with the new Pentax K-1. The label WR in their names indicates that these lenses are sealed and weather-resistant, while the SP stands for Super Protect coatings that cover the front elements of the two lenses and that repel water. As for the HD abbreviation, it suggests that these elements of the full-frame lenses are covered with a high-grade multi-layer high-definition coating, which results in high-contrast images free of flare and ghosting, even in highly demanding light conditions.
The Pentax 15-30mm f/2.8 ED SDM WR also sports fast f/2.8 aperture, which is perfect for shooting nightscapes and starry skies, it features 18 elements in 13 groups, three of which are ED and one is aspherical, as well as a built-in SDM (Supersonic Direct-drive Motor) motor, which brings silent and fast autofocus.
As for the Pentax 28-105mm f/3.5-5.6 ED DC WR, it boasts a much wider range, but, on the other hand, its dimensions are more compact and its weight smaller (440g in relation to 1040g, which is how much the 15-30mm f/2.8 weighs). It features 15 elements in 11 groups, one of which is ED, and two are aspherical, and it is equipped with a DC micromotor as well.
The filter diameter of both of these zoom lenses is 62mm, whereas their diaphragms consist of 9 blades.
The long-awaited Pentax K-1 has already arrived at the market, and so are the new lenses Pentax-D HD FA 15-30mm f/2.8 ED SDM WR and Pentax-D HD FA 28-105mm f/3.5-5.6 ED DC WR. Their prices are $1799, $1499, and $499, respectively.
