Basic Specifications and Functions

How does this model differ from the K-5 II series models?


Differences in functions from those on the K-5 II series models are listed below.

- Produces high-resolution images with approximately 24 effective megapixels using a new CMOS sensor
- Equipped with an AA Filter Simulator function developed based on the Shake Reduction (SR) feature
- Equipped with SAFOX 11, a newly developed Autofocus (AF) module
- Comes with PRIME III, a new image processing engine
- Equipped with a 3.2” (3:2) color LCD with approximately 1,030,000 dots and anti-reflection (AR) coating and air-gapless glass with excellent visibility perfect for outdoor applications
- Equipped with an optical viewfinder with a unique new design
- Includes a high-speed continuous shooting function (up to 8.3 fps)
- Provides improved exposure accuracy using a new approx. 86K-pixel RGB metering sensor
- Equipped with the Multi Auto White Balance function
- Comes with enhanced movie functions
- Comes with a Dual Memory Card Slot
- Includes a function for connecting to a smartphone using the FLUCARD FOR PENTAX 16GB Flucard (sold separately)
- Compatible with SDHC and SDXC UHS-I card standards
What does the “AA Filter Simulator” function do?


It produces a moiré reduction effect using the Shake Reduction unit. There are three settings to choose from: OFF, Type1, and Type2.
What are some of the features of the approx. 86K-pixel RGB metering sensor?


The metering sensor in the K-3 is more sophisticated than that in previous models and also works to measure color information. This allows for more accurate metering due to a greater amount of information being collected. The sensor works well even in low-light situations with levels down to -3 EV (when a FA 50-mm F1.4 lens is used).
What are the differences between the new Multi Auto White Balance function and the Auto White Balance function used previously?


The previous white balance function worked on the image display as a whole. The new Multi Auto White Balance function splits the image into different areas and runs white balance on each area separately.
For example:
- Images split into areas affected by the light from the flash and areas not affected by the flash.
- Images split into areas lit by natural sunlight and areas lit by artificial lighting equipment.
 Calculations are made for each separate area, ensuring that a more natural-looking white balance effect is achieved under a mixture of lighting conditions from various different light sources.
How many AF points are there total?


There are 27 AF points altogether, and 25 of those are cross-type AF points.
How many f2.8 AF point sensors does the K-3 have?


Three. There is a line sensor for measuring flux located at the center as well as one above and one below.

Can Refconverter A/M be used with this camera?


Yes, it can.
Some vignetting may occur in the information display in the viewfinder when using the Refconverter M, however.
Can a battery grip be used with the K-3? Can the same battery grip as for the K-5/K-5 II be used with this camera?


The optional Battery Grip D-BG5 (sold separately) can be used with the K-3. If a Lithium-ion Battery D-LI90P is inserted into both the camera and the battery grip, the number of recordable images will be increased. AA batteries (qty. 6) can be used if the tray is changed.
*The Battery Grip D-BG1 (for *ist D series models), D-BG2 (for K20D, K10D models), D-BG3 (for K200D models), and D-BG4 (for K-7, K-5, K-5 II, K-5 IIs models) cannot be used with the K-3.
Can polarizing filters be used with this camera?


Circular type polarizing filters (C-PL/Circular PL) can be used. Normal, non-circular polarizing filters may adversely affect the exposure and AF and thus cannot be used.
What image recording formats are used?


The camera records images in the versatile JPEG format or the high-quality and fully editable RAW (PEF/DNG) format. You can also select JPEG+RAW (PEF/DNG) and record in both formats simultaneously.
Can image rotation information be saved for images taken while the camera is held vertically or horizontally?


Yes, it can.
Does the camera have a Superimpose function?


The camera is equipped with the Superimpose AF Area function that causes the selected AF points to light up red in the viewfinder.
[Superimpose AF Area] can be toggled ON/OFF in the [Custom Setting] menu.
Can you switch between AF points as desired?


Yes, you can select a desired focusing area from any of the 27 AF points within the AF frame.
What type of shake reduction system is used?


The K-3 is equipped with a Sensor-Shift Shake Reduction system built right into the body of the camera.
How effective is the Shake Reduction in terms of shutter speed steps?


The effect of Shake Reduction is equivalent to up to around 3.5 EV steps in shutter speed.
*The Shake Reduction effect may vary depending on the focal length of the lens, distance to the subject, shooting conditions, and individual technique.
Will the Shake Reduction (SR) function work with other manufacturers’ lenses?


Camera operation (including exposure and the accuracy of focus) cannot be guaranteed when lenses from other manufacturers are used. Lenses from other manufacturers can be used if they are K-mount lenses. However, responsibility for such use shall fall squarely on the user. We shall accept no responsibility or liability for problems arising from the use of such lenses. We will assume no responsibility or liability for accidents, damages, and malfunctions resulting from the use of lenses made by other manufacturers. Furthermore, while the Shake Reduction mechanism will still function with such lenses, the effectiveness of the results cannot be guaranteed.
Are there any lenses that the Shake Reduction (SR) function cannot be used with?


No, there are not. The SR function on the K-3 can be used with all supported lenses. Use a focal length in the range from 8 mm to 2000 mm for lenses for which focal length information cannot be obtained.
What is the relationship between camera shake and shutter speed?


It is generally said that the slowest shutter speed to use to avoid blur is 1/(focal length) second (in 35mm format).
However, with cameras featuring an APS-C size image sensor (like the K-3), please consider the focal length as 1.5 times longer.
For example, a 200 mm lens is equivalent to a 300 mm lens in 35 mm format, and thus, generally speaking, the slowest shutter speed for such a lens is 1/300 sec. You can expect Shake Reduction to be effective at shutter speeds 3 steps slower than 1/300.
Would it be OK to always leave the Shake Reduction (SR) function ON all the time?


It is recommended that the SR function be left on for manual shooting with the camera in hand.
*Turn off the Shake Reduction function when using the camera with a tripod.
*The function turns OFF automatically when the B (Bulb Exposure) shooting mode is selected and Drive Mode is set to Self-timer, Remote Control, or Mirror Lock-up Shooting.
Can the effect of the Shake Reduction function be checked before a picture is taken?


The effects of the Shake Reduction function cannot be checked beforehand from the viewfinder image. However, if Live View is displayed, the effects can be viewed on the image monitor before images are taken.
How many different Custom Image options are available?


Select from the following eleven finishing touches: Bright, Natural, Portrait, Landscape, Vibrant, Radiant, Muted, Bleach Bypass, Reversal Film, Monochrome, and Cross Processing.
*The default setting is [Bright].
What is the Digital Filter?


This mode lets you change the color tone of an image and perform special processing on an image. The Digital Filter can be applied when a picture is taken. You can also apply digital filter effects to images that have been shot in playback mode.

Is it possible to drive the autofocus using the ultrasonic motor located inside the lens?


When a motor-driven lens is attached to the K-3, the camera automatically switches to autofocus that is driven by the motor inside the lens.
What kind of function is "Lens Correction" and what different types are available?


It reduces lateral chromatic aberrations, distortions, peripheral illuminations, and color fringes that occur during digital processing due to lens properties. These are the four options available.

*[Color Fringe Correction] is only available during RAW file development.
*It will take longer to save images in high-speed continuous shooting mode when [Lens Correction] is ON except for with the initial settings. With the initial settings, [Lateral Chromatic Aberration Adjustment] is set to ON and [Distortion Correction] and [Peripheral Illumination Correction] are turned OFF.
*The corrected image is saved as a JPEG image.
*Lens Correction is not used on RAW files. When the camera or included software develops an image in the RAW format, Lens Correction is performed on the image and the results saved as a new JPEG file. (Only Lateral Chromatic Aberration Adjustment and Distortion Correction are applied).
*Lens Correction may not be performed in all cases depending on the lens in use and selected settings.
Can I use other manufacturers' replacement lenses with the K-3?


Camera operation (including exposure and the accuracy of focus) cannot be guaranteed when lenses from other manufacturers are used. Lenses from other manufacturers can be used if they are K-mount lenses. However, responsibility for such use shall fall squarely on the user. We shall accept no responsibility or liability for problems arising from the use of such lenses. We will assume no responsibility or liability for accidents, damages, and malfunctions resulting from the use of lenses made by other manufacturers. Furthermore, while the Shake Reduction mechanism will still function with such lenses, the effectiveness of the results cannot be guaranteed.

Camera Shooting Functions

How many frames/second can be shot in Continuous Shooting mode?


The approximate fps rates for various setting conditions are as listed below.

When the file format is JPEG, the recorded pixels is 24M, and the quality level is ★★★ (Best)
- Approx. 8.3 fps max./Up to approx. 60 frames for Continuous H
- Approx. 4.5 fps max./Up to approx. 100 frames for Continuous M
- Approx. 3.0 fps max./Up to approx. 200 frames for Continuous L

When the file format is RAW
- Approx. 8.3 fps max./Up to approx. 23 frames for Continuous H
- Approx. 4.5 fps max./Up to approx. 32 frames for Continuous M
- Approx. 3.0 fps max./Up to approx. 52 frames for Continuous L

*The values given were collected under our measurement conditions using a sensitivity of ISO 100. The number of recordable images for continuous shooting may drop slightly depending on setting conditions such as the ISO setting.
*The continuous shooting speed of 8.3 fps does not depend on the writing speed of SD Memory Cards. However, the fps for continuous shooting may drop slightly with SD Memory Cards with a low writing speed.
Can a remote control be used with this camera?


Yes, it can. The optional Remote Control Waterproof O-RC1 and Remote Control F are available for use with this camera.

What is [Slow Shutter Speed NR]?


When you use a digital camera with a long exposure to shoot pictures, image noise (image roughness or unevenness) becomes more noticeable. The K-3 has a Noise Reduction function that reduces image noise.
*When [Slow Shutter Speed NR] is ON, it will take longer to save images.
*The default setting is [Auto]. The camera determines conditions such as exposure time, sensitivity, and internal temperature and automatically applies Noise Reduction as necessary.
 On: Applies Noise Reduction when the exposure time is longer than 1 second.
 Off: Does not apply Noise Reduction.
What is [High-ISO NR]?


When you use a digital camera with a high sensitivity setting to shoot pictures, image noise (image roughness or unevenness) becomes noticeable. The K-3 has a Noise Reduction function that reduces image noise.
*When [High-ISO NR] is ON, it will take longer to save images.
*The default setting is [Auto]. The camera determines whether the Noise Reduction function is On (Low/Medium/High) or Off from the sensitivity.
 Custom: Applies Noise Reduction at user-defined levels for each ISO setting.
*It may take a slightly longer time for basic image processing in the high-sensitivity band of Expanded Sensitivity to be completed, independent of what the Noise Reduction settings are.
Does the K-3 have an AF assist light?


Yes, it does. The AF assist light is activated when AF.S mode is selected.

Flash

What is the guide number of the built-in flash?


The guide number is approximately 13 (ISO 100/m).
What is the maximum focal length covered by the built-in flash?


The flash covers the angle of view of an 18 mm lens (35 mm equivalent: 28 mm lens).

Movies

What are the specifications for movie recording?


The video compression format is H.264/MPEG-4 AVC, and the file format used is *.mov, QuickTime. Interval movies are recorded in MotionJPEG (AVI) format. Monaural sound is recorded (when the built-in microphone is used).
- There are two options for the number of recorded pixels and framerate: Full HD (1920×1080, 16:9, 60i fps/50i fps/30p fps/25p fps/24p fps) and HD (1280×720, 16:9, 60p fps/50p fps/30p fps/25p fps/24p fps).

*A movie can be recorded continuously for up to 4 GB or around 25 minutes. When the SD Memory Card is full, recording stops and the movie is saved.
*If the internal temperature of the camera becomes high during movie recording, the recording may be terminated to protect the camera circuitry.
*When the built-in microphone (monaural) is used, camera operation sounds are also recorded. It is recommended that the camera be set up on a tripod or otherwise secured in a stable location and not touched while movies are being recorded to avoid this.
*You can record stereo sound by connecting a commercially available stereo microphone to the microphone terminal on the camera.
*There is no dedicated external stereo microphone available as an optional accessory. Use a commercially available one instead.
Does the autofocus system operate while movies are being recorded?


Autofocus will run even while movies are being recorded if you press the AF button on the back of the camera.
*Note that the sound made by the AF function will be recorded as part of the movie.
Can movies recorded using 4K Interval Movie Record be played back on a computer?


Yes, but you will need to use a computer that supports 4K movie playback in order to play back movies recorded in 4K Interval Movie Record mode.
What are the features of the Interval HDR Movie Record function?


The Interval HDR Movie Record function is used to convert a single shot captured in Interval Movie Record mode into a three-shot composite HDR image file.
This produces an interval with a wider dynamic range and the distinctive added effects of HDR.
Can I adjust the exposure while recording a movie?


You can use the Automatic Exposure function in P/Av/Tav modes. The exposure settings range from -2 to +2.
