A full-frame SLR from the PENTAX K series
What’s the best camera for a photographer? Throughout more than 50 years as a leading SLR camera manufacturer, PENTAX has always thought very seriously about this question, and developed the original technologies to provide good answers. It’s a history of never-ending innovation and evolution. Based on its experiences and expertise accumulated over these years, PENTAX now has the final answer: a new 35mm full-frame digital SLR camera named PENTAX K-1. Proudly carrying the number “1” in its name, the K-1 reigns as the flagship of the acclaimed PENTAX K series.
While inheriting PENTAX’s traditional compact, durable body design, the K-1 adds essential values to the 35mm full-frame format, including state-of-the-art high-resolution technologies drawn from PENTAX’s development of medium-format models, an array of exclusive shooting features, and remarkable environmental adaptability in the field.
True to its number-1 naming, the PENTAX K-1 signifies the arrival of a new era in 35mm full-frame digital SLR cameras.
35mm full-frame CMOS image sensor
Exceptional imaging power assured by a large-format sensor. The K-1 incorporates a newly developed 35mm full-frame CMOS image sensor, one that assures the highest image quality to be found in the K-mount SLR series. Thanks to its large imaging area and wide pixel pitch, this high-pixel sensor delivers lively, true-to-life images with rich gradation and minimal noise. Its shallow depth of field allows you to control the sense of depth and bokeh (defocused) effect at will.
Approximately 36.4 effective megapixels
Exceptional resolving power supported by a high-resolution, AA-filter-free design. Thanks to its approximately 36.4 effective megapixels, the K-1 delivers breathtaking, true-to-life images—the kind that will seize the viewer’s imagination. Its exceptional resolving power captures each leaf of a distant tree or every drop of a spray in the finest detail. Since it provides image data large enough to produce a brilliant A2-size print (at 300dpi), the photographer is assured of great flexibility in image composition, either by cropping the image during shooting, or trimming the captured image during processing. By processing large volumes of data with its 14-bit image-processing system, the K-1 delivers beautiful, rich-gradation images.
AA filter simulator
State-of-the-art mechanism to optically minimize moiré and false colour. By using the camera’s SR mechanism to apply microscopic vibrations to the image sensor, the PENTAX-original AA (anti-aliasing) filter simulator effectively minimizes moiré and false color along the image’s edges, which are common problems when shooting subjects with minute patterns. The K-1 allows you to faithfully reproduce your creative intention on a captured image, either by simulating the AA-filter effect for well-balanced images or by opting for the AA-filter-free mode for greater resolving power.
A new imaging engine optimized for a 35mm full-frame image circle. The K-1 features a newly designed PRIME IV imaging engine. Compared with the previous PRIME III version, it is fine-tuned to process higher-resolution images, while boosting the operating frequency by nearly 50 percent. Its noise-processing algorithm has also been upgraded to capture beautiful, fine-gradation images at higher sensitivities. A combination of an advanced scene analysis system and new image-processing functions helps improve the accuracy and reliability of image reproduction.
A combination of super-high sensitivity and exceptional image resolution. By taking full advantage of the image sensor excelled in noise-resistance performance and the PRIME IV imaging engine, the K-1 provides a top sensitivity of ISO 204800 (at standard output sensitivity). This not only delivers high-resolution images free of tone jumps and graininess at high-sensitivity settings, but also improves image quality in the low-sensitivity range. Since the K-1 allows you to raise the sensitivity level to capture images equal in image quality to those taken at lower sensitivities, it expands the boundaries of photographic expression.
Pixel Shift Resolution System
Reproduction of true-to-life, super-high-resolution images beyond actual pixels. Reinforced with the SR (Shake Reduction) mechanism, the K-1’s Pixel Shift Resolution System captures four images of the same scene by shifting the image sensor by a single pixel for each image, then synthesizes them into a single, super-high-resolution composite image. Compared to the conventional Bayer system, this innovative system obtains all RGB color data in each pixel to deliver beautiful images with far more truthful colors and much finer details, without any hint of false color. This system also reduces high-sensitivity noise to a minimum. The difference in image quality is evident at a glance, even without magnifying the captured image on a computer screen or producing a large-size print. Images captured by the Pixel Shift Resolution System can be saved as RAW-format files. You can developed these files within the camera body while adjusting various parameters or turning the Pixel Shift Resolution effect on and off to create a new image.
Motion Correction function
When shooting an image with the Pixel Shift Resolution System, the K-1 provides a new Motion Correction function. When this function is activated, the camera automatically detects the amount of subject motion during continuous shooting and minimizes negative effects during the synthesizing process.
Minimizing diffraction blur at small apertures. This function compensates for the drop in resolving power caused by the diffraction during image processing. Based on obtained image data, it provides an exposure compensation of up to approximately two aperture steps, making it useful for such subjects as landscapes, which requires you to close down the aperture to widen a depth of field without compromising the resolving power.
Lens Aberration Correction and Fringe Compensation
High-quality image reproduction across the image field, with effective compensation of aberrations. The K-1 effectively compensates for the distortion, vignetting and chromatic aberration caused by specific lens properties, and captures high-quality images with edge-to-edge sharpness. It even compensates for the fringe effect during RAW-data development.
Fine Sharpness and Extra Sharpness
Sharpness-enhancing tools to greatly improve the image rendition of high-pixel photography. No matter how many pixels and how much resolving power an image sensor may provide, the captured image can appear as a low-resolution image if the subject is outlined with thick lines. The K-1’s Fine Sharpness function outlines the subject with thinner, more natural lines than those created by normal processing to produce a high-quality, fine-detailed image. It allows you to create a fine piece of art, with a true-to-life description of the subject. The K-1 also provides an Extra Sharpness function, which emphasizes the subject’s outline more prominently with much finer lines, making it particularly useful for enhancing the outline of a low-contrast subject.
SR II in-body shake reduction mechanism
The world’s first five-axis, five-shutter-step camera shake compensation. The PENTAX-original sensor-shift-type shake reduction mechanism has been upgraded to provide optimum compensation for all lenses used in handheld shooting. The new-generation SR II (Shake Reduction II) features a five-axis mechanism to compensate for camera shake caused by horizontal and vertical shift (often generated in macro photography) and camera shake caused by roll, which is difficult to handle by lens-installed shake reduction mechanisms, in addition to more common camera shake caused by pitch and yaw. The SR II unit is controlled with great precision as soon as the camera’s power is turned on, and provides a wide compensation range — as much as five shutter steps — to expand the limits of handheld shooting.
Flexible Tilt-Type LCD monitor
Innovative mechanism to tilt the monitor to any desired angle along the optical axis. Aiming at aligning the photographer’s line of sight precisely with the camera’s optical axis while providing a flexible angle adjustment, PENTAX has designed an ideal LCD monitor for the K-1 by creating an innovative mechanism that supports the monitor with four stays. This monitor has reached two difficult goals that conventional monitors have failed to attain: no deviation from the optical axis; and unrestricted tilt in all directions, horizontally or vertically. You can even tilt it up to a nearly 90-degree angle for low-angle and waist-level photography.
Optical viewfinder with a nearly100% field of view
Assuring a clear view of the field and ease of focus. The K-1’s optical viewfinder provides a nearly 100-percent field of view and a 0.7-times magnification to deliver a sharp, crisp view of the subject and a large, well-defined image field, both of which are the benefits of the 35mm full-frame SLR camera. This viewfinder also provides a clear view of the image field free of aberrations, even at the edges. Its Natural-Bright-Matte III focusing screen makes it easy to identify the in-focus point, even during manual-focus operation.
Dependable dustproof, weather-resistant construction
A completely environment-resistant imaging system, with a weather-resistant lens. A combination of the K-1’s 87 sealing parts and the optional D-BG6 Battery Grip’s watertight body prevents the intrusion of water and dust into their interior. When an AW- or WR-series lens is mounted, the K-1 and its lens forms a remarkable digital imaging system totally resistant to demanding environmental factors.
33-point AF system with 25 cross-shaped sensors
Assuring reliable, unfailing focus on the subject. The K-1’s sophisticated 33-point AF system has a high-density distribution of AF sensors to effectively monitor crucial areas of the image field, while providing 25 cross-shaped sensors to assure extra-accurate focus on the subject.
