User-friendly operation and durable body for challenging shooting locations

Optical finder with a 100% field of view
to deliver a sharp, clear viewfinder image at 0.95X magnification

The K-3 features an optical finder with a nearly 100-percent field of view to provide a clear view of the image field, even at the edges. Thanks to the application of a new coating to the reflective surfaces, its light transmittance is almost 15 percent higher than that of the K-5II’s. In addition, the eyepiece optics have been completely redesigned to deliver a large, crisp image at 0.95-times magnification (with a 50mm lens at infinity).*

Wireless LAN remote control operation

The K-3 accepts the optional O-FC1 FLUCARD FOR PENTAX 16GB to provide wireless LAN functions** using a smartphone or tablet computer. You can release the K-3’s shutter and change exposure settings from a distance while checking the Live View image, and download and browse captured images on your smartphone/tablet monitor.

supported by iOS and Android operating systems.

3.2-inch Air Gapless LCD monitor
for outstanding visibility in the field and superior scratch resistance

The K-3’s Air Gapless LCD monitor has a special resin layer applied between the protective panel and the LCD screen to effectively cut down the reflection and dispersion of light and assure excellent visibility even under bright sunshine. Its 3.2-inch screen displays a large subject image at 3:2 aspect ratio, while the protective panel is made of tempered glass to keep it free of scratches and abrasions.

Dual SD card slot
for efficient image data filing on two memory cards

The K-3’s card slot accepts two SD memory cards, with a choice of three data storage modes: “Serial” to store a large volume of data, “Duplicate” for simplified data backup, and “RAW/JPEG Division” to separate data files based on the recording format.
Note: The second receptacle of the SD card slot accepts an Eye-Fi card or FLUCARD to enable wireless LAN functions.

Newly installed control parts
for delay-free, direct-access control

In order to provide swift, intuitive control of advanced functions and user-friendly features, the K-3 features more direct-access control buttons and levers than ever before. You can even operate them without removing the eye from the viewfinder.

  • AF mode button

    Positioned on the front panel, this button provides two AF-related functions. While pressing this button, you can turn the front e-dial to shift the AF mode, or use the rear e-dial to switch the AF select area.

  • Mode dial unlock lever

    This lever has two positions to prevent accidental operational errors: one position allows you to turn the mode dial only when the lock button is pressed; the other position frees the mode dial lock for speedier operation.

Magnesium alloy casing and metallic chassis
for exceptional rigidity, outstanding durability and reduced weight

The K-3’s top, bottom and side panels are made of highly rigid, lightweight and shock-resistant magnesium alloy. Its chassis, which houses the core components, is made of high-rigidity, corrosion-resistant stainless steel.

Cold resistance down to -10°C
for solid, dependable performance at freezing temperatures

The K-3 has been subjected to a series of cold-resistance tests at freezing temperatures down to -10°C. Every single operation was closely examined during these tests, including the operational stability of electronic circuits, the operating precision of mechanical parts, the strength and response of optical components, and the fluctuation of battery voltage. That’s why you can always depend on the K-3, even in cold environments.

Dustproof, weather-resistant construction
to assure solid performance under demanding outdoor conditions

The K-3 features a dependable dustproof, weather-resistant construction to prevent the intrusion of water, moisture and dust into its interior. A total of 92 special seals are applied to the crucial areas of the K-3 body, including control parts, panel joints and cover hinges, to assure an airtight body. The optional D-BG5 Battery Grip also features the same weather-resistant, dustproof construction.

AW/WR-series lenses
to complete the weather-resistant, dustproof digital imaging system


SmC PENTAX-DA18-135mm F3.5-5.6ED AL[IF] DC WR

To optimize the benefit of lens interchangeability, PENTAX offers an extensive lineup of the weather-resistant, dustproof AW and weather-resistant WR series.

* AW stands for All Weather; WR for Weather Resistant;.

DR II (Dust Removal II) mechanism
to clean the CMOS sensor with supersonic vibration

This innovative mechanism effectively removes all dust particles clinging to the surface of the CMOS image sensor unit by vibrating the optical glass panel at supersonic speed.

Dust alert system
for early detection and efficient removal of dust particles

This system detects dust particles clinging to the CMOS image sensor, and indicates their position on the LCD monitor. Once the dust particles have been identified, they can be easily removed on the spot — either by activating the DR II mechanism, or by using the optional O-ICK1 Image-Sensor Cleaning Kit or a dust blower.

Dependable shutter unit
to withstand more than 200,000 shutter releases**

The K-3’s shutter unit has been subjected to a series of exacting performance tests to prove its durability. It assures outstanding precision and excellent response even after years of use.
