K I

The K-1 overcomes challenging field conditions, such as poor weather, darkness and freezing temperatures.

  • Horizontal and vertical shift

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.

  • For a 35mm full-frame digital SLR camera, as of February 2016 (based on RICOH IMAGING research).
  • *During Live View shooting, this mechanism does not compensate for camera shake caused by horizontally and vertical shift.
  • ** Measured in conformity to CIPA standards, using an HD PENTAX-D FA 28-105mm F3.5-5.6ED DC WR lens at a focal length of 105mm.

Compatible with panning shots

When taking a panning shot, this mechanism efficiently controls the SR unit to detect only the direction of the camera’s movement, while compensating for all other affecting vectors. Because of this, the K-1 captures beautiful, high-resolution images both in normal shooting and panning photography, without requiring any switching operation.

Operation Assist Light  Supporting camera operations in the dark

Four Operation Assist Lights are strategically positioned around the camera body: at the upper side of the lens mount, behind the LCD monitor, at the memory card slot, and at the cable switch terminal. With a push of the illumination button, you can turn them on* to facilitate lens and memory card changes, control button operations, and attachment and removal of a cable switch, for more efficient, comfortable shooting of nighttime outdoor scenes and poorly lit indoor subjects.

  • The LED lights can be switched on and off individually. They are all set to the off mode at default setting.

High-precision AE/AF operation at –3EV illumination Extra-accurate auto-exposure and autofocus control, even in the dark

An illumination level of –3EV makes it difficult to see a subject with the naked eye, and almost impossible to make accurate focus with manual focusing. Even under such low-illumination conditions, the K-1 assures high-precision auto-exposure and autofocus operations.* Thanks to its upgraded algorithm, its autofocus response time for poorly illuminated subjects is greatly reduced. Coupled with its super-high-resolution imaging power, the K-1 delivers exceptional shooting performance in dark locations.

  • Light metering measured at ISO 100 and with a 50mm F1.4 lens; focusing measured at ISO 100, at room temperature and with 25 middle sensors.

Outdoor-oriented LCD monitor  Single-action setting of LCD monitor’s brightness

With a single push of a button, the K-1’s new Outdoor View Setting mode displays five brightness settings on its LCD monitor, allowing you to easily and quickly set the desired brightness level for a given location — brightening the monitor under dazzling sunshine or darkening it under starlit skies.

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.

  • AW stands for All Weather (dustproof and weather-resistant construction), while WR stands for Weather Resistant (simplified weather-resistant construction).

-10°C cold-resistant construction Unmatched reliability proven under vigorous testing conditions

Anticipating use in cold locations, PENTAX has subjected the K-1 to exacting environmental tests at temperatures as low as –10°C, and gathered a vast array of data on operational precision, response and stability of mechanisms and circuits, as well as fluctuations in battery voltage.* As the result, the K-1 assures solid, trouble-free operation even at freezing temperatures.

  • Battery performance declines as the temperature goes down. When shooting in cold environments, the user is advised to carry spare batteries and keep them warm by storing them in an inside pocket.

DRII (Dust Removal II) mechanism Effective removal of foreign particles from the image sensor

Using its piezoelectric element, this innovative mechanism applies ultrasonic vibrations to the optical glass panel placed in front of the image sensor. This effectively removes all dust particles clinging to the image sensor surface, and prevents annoying dust spots from appearing on a captured image.

  • UV/IR-cut filter
  • Absorption-type IR-cut glass
  • Piezoelectric element
  • CMOS image sensor

High-rigidity, extra-durable body A shell structure shielding a metallic chassis with a magnesium alloy casing

The K-1’s exterior casing is made of highly rigid, lightweight magnesium alloy, which provides excellent shock-resistance and electromagnetic shielding performance. By coupling it with a high-rigidity metallic chassis housing the core components, the K-1 forms a compound structure to assure outstanding durability and exceptional reliability.

PRIME Ⅳ

Extra-durable shutter unit  Withstanding 300,000 shutter releases for professional use

After a series of exacting performance tests, the K-1’s shutter unit has proven its exceptional durability by withstanding a total of 300,000 shutter releases. It assures outstanding operational precision and exceptional durability required for exacting professional work.
