36.4 MP Full Frame Sensor
The K-1’s unique full frame sensor is an AA filterless design that prioritizes image resolution. Coupled with the new PRIME IV imaging engine, it features 14-bit RAW-format image recording capability and super-high-sensitivity shooting up to ISO 204800, producing stunning high-resolution images in any shooting environment.
New SR II In-Camera Shake Reduction
The SR II five-axis shake reduction mechanism is redesigned to operate flawlessly with the new large full frame image sensor. Because SR II shake reduction is body-based, it works with all full frame compatible PENTAX interchangeable lenses. SR II shake reduction automatically detects the direction of the camera’s movement, and efficiently controls the SR unit to always produce the best image possible.
Pixel Shift Resolution System with Motion Correction
The K-1 uses the latest super-resolution technology allowing for sharp filterless performance, reducing moiré by capturing four images of the same scene, shifting the image sensor by a single pixel using SR II shake reduction technology, and then composing the four images into a single image. As SR II tilts the image sensor unit in all directions, it provides a host of handy additional shooting features, including auto level compensation and image-composition fine-adjustment.
SAFOX 12 with 33 AF Sensor Points
The new SAFOX 12 AF sensor module features 33 AF sensors (25 cross-type sensors positioned in the middle). The center sensor and the two sensors located just above and below it are designed to detect the light flux of an F2.8 lens, making it easy to obtain pinpoint focus on a subject when using a large-aperture lens.
Dual Card Slot
The K-1’s card slot accepts two SD memory cards, with a choice of three data filing modes: “Serial” to store a large volume of data successively from one card to another; “Duplicate” (simultaneous filing) for simplified data backup, and “RAW/JPEG Division” to separate data files based on the recording format. It is also possible to copy an image stored on one card to another.
Unique PENTAX Pentaprism Optical Viewfinder
Newly developed for its 35mm full-frame design, the K-1’s optical viewfinder provides a nearly 100-percent field of view and an approximately 0.70-times magnification. A Natural Bright Matt III focusing screen allows ease of focusing and a true-to-life rendition of defocused areas in the viewfinder image.
Operation Assist LED Lighting
The operation assist light function provides LED lights above the lens mount, behind the LCD monitor, at the memory card slot, and at the cable switch terminal to facilitate fast and easy operation in low light environments.
New PRIME IV 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.
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.
AA filter simulator
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.
Customize your K-1 to suit you preferences
The K-1 provides a wide range of customization settings to optimize the ease and comfort of camera operations. These settings have been designed to expand the functions of the USER Mode and the Fx (function) buttons, improve accessibility to desired functions on the control panel, and prevent accidental operational errors.
(A) USER Mode
Five different combinations of the most frequently used functions can be assigned to this mode to handle specific subjects or creative intentions.
(B) Control panel
This panel displays a list of the functions and their status on the LCD panel, while allowing you to change the contents and/or order of listed functions to suit your shooting style.
(C) Lock button
In order to prevent accidental setting changes, the K-1 provides a lock button to temporarily inactivate control buttons and dials. It offers you a choice of two lock functions: Type 1 to prevent unintended exposure setting changes; and Type 2 to prevent operational setting changes.
(1) Fx1 button One function from seven options can be assigned (default: RAW)
(2) Fx2 button Another function from seven options can be assigned (default: Outdoor View Setting)
(3) AF button One of the functions governing AF operation can be assigned.
(4) Preview lever An optical or digital preview mode can be assigned.
(5) E-dial A set of exposure mode can be assigned.
Dependable dustproof, weather-resistant construction
Constructed of sturdy yet lightweight magnesium alloy with the inclusion of 87 sealing parts in the body, the K-1 also boasts a dustproof, weather-resistant and cold-resistant construction.
All APS-C-format, K-mount interchangeable lenses are usable on the K-1
From ultra-wide angle to super telephoto, an entire selection of high-performance DA-series lenses can be used on the K-1 without any modification. They deliver exceptional image quality, despite their compact, lightweight design.
