    <Shake Reduction (SR)>

    How effective is the Shake Reduction in terms of shutter speed steps?
    The effect of Shake Reduction is equivalent approx up to 4 shutter speeds.

    * The Shake Reduction effect may vary depending on the focal length of the lens, distance to the subject, shooting conditions and individual technique.

    It is generally said that the slowest shutter speed to avoid blur is 1/focal length.
    However, with cameras featuring an APS-C size image sensor, please consider the focal length as 1.5 times longer (35 mm-equivalent focal length).
    For example, a 100 mm lens is equivalent to a 150 mm lens in 35 mm format so, generally speaking, the slowest shutter speed for such lens is 1/150 sec. You can expect Shake Reduction to be effective at shutter speeds 2.5 to 4 steps slower than 1/150.
    Will the Shake Reduction (SR) function work with non-PENTAX lenses?
    The Shake Reduction mechanism will function but the effectiveness of the results can not be guaranteed. PENTAX will assume no responsibility or liability for accidents, damages and malfunctions resulting from the use of lenses made by other manufacturers.
    Are there any lenses with which the Shake Reduction (SR) function cannot be used?
    No, there isn't one. This function can be used with all PENTAX lenses that can be attached to the camera.

    * The [Input Focal Length] setting menu does not appear when using a lens that supports automatic acquisition of lens information such as focal length because [Focal Length] is set automatically. (DA, DA L, D FA, FA J, FA, or F is set automatically)
    If type of lens that does not support automatic acquisition of lens information such as focal length is used, the [Input Focal Length] menu appears. Set [Focal Length] manually on the [Input Focal Length] setting menu.

    * When using lens without the A position on the aperture or with the aperture set to a position other than the A position, set [22. Using aperture ring] on the [C Custom Setting 4] menu to [2. Permitted].

    Would it be better to leave the SR function always on?
    When you take a picture with a handheld camera, we recommend that the Shake Reduction switch is always ON. When using the camera on a tripod, turn off the Shake Reduction switch.
    Does the battery life change depending on the position of the Shake Reduction switch?
    No, it does not.
    Can the Shake Reduction function be used in B (Bulb) mode?

    *The Shake Reduction function is automatically turned off in the following situations: When using the self-time, remote control shooting, shooting in B (Bulb) mode or using wireless mode with an external flash and HDR Capture.

    Will the Shake Reduction (SR) function work with slow synchronization of the flash?
    Yes, it will function.
    Can the effect of the Shake Reduction function be checked in the viewfinder?

    <Lenses that can be used>

    What kind of lens is included in the K-x lens kit?
    smc PENTAX-DA L18-55mmF3.5-5.6 AL lens is included.
    Can the SDM autofocus system be used?

    When [22. Using Aperture Ring] is set to [Permitted] in the [C Custom Setting 4] menu, the shutter Can be released even if the aperture ring of the D FA, FA, F or A lens is not set to the A (Auto) Position or a lens without an A position is attached. However, the features will be restricted as shown below.

    * The area captured with this camera will differ from that captured with a 35 mm SLR camera even if the same lens is used because the format size for 35 mm film and CCD sensor are different. The area captured will be equivalent to that captured with a 35 mm SLR camera using a lens with a focal length approximately 1.5 times longer than the lens used.

    *6 To use an F/FA soft 85mm f/2.8 lens or FA soft 28mm f/2.8 lens, set [22. Using aperture ring] in the [C Custom Setting 4] menu to [Permitted]. Pictures can be taken with the aperture you set, but only within manual aperture range.
    *7 The AF point is fixed to spot.
    *8 Av(Aperture Priority) Automatic Exposure with the aperture open. (Adjusting the aperture ring has no effect on the actual aperture value.)

    Can PENTAX 67 lenses, PENTAX 645 lenses or S (Screw mount) lenses be used with this camera?
    These types of lenses can be attached using the respective K-mount adapter.
    However, shutter release will not be available with default settings. To allow shutter release, change the following settings.
    (1) Set [22.Using aperture ring] to [Permitted] in the Custom Setting menu.
    (2) Set the focus mode lever to MF.
    Av (Aperture Priority) mode and M (Manual) mode can be used but an exposure error may occur.
    In the viewfinder and status screen, [F--] appears for the aperture indicator.
    The camera operates in Av (Aperture Priority) mode even if the mode dial is Auto picture, Picture mode, SCN, Program, SV and TV mode.
    How does the area captured change when using medium format lenses?
    Focal length is a characteristic of the lens, whether it is used with 35 mm format or medium format (645 or 67) cameras. In 35 mm equivalent terms, the area captured will be the same as that of an image captured using a lens with a focal length approximately 1.5 times longer than the lens used.

    (Example) If you used the following lens with K-x
    smc PENTAX-FA 50mmF1.4 → Focal length is equivalent to a 75mm lens on a 35mm camera.
    smc PENTAX-FA645 75mmF2.8 → Focal length is equivalent to a 114mm lens on a 35mm camera.
    smc PENTAX 67 105mmF2.4 → Focal length is equivalent to a 160mm lens on a 35mm camera.
    What lens is compatible with Lens Correction?
    DA, DA L, and the D FA lens are compatible.
    What function is "Lens Correction"?
    Reduces distortions and lateral chromatic aberrations occurring due to lens properties by digital processing.

    *The corrected image is saved as JPEG image.
    *The RAW data cannot be corrected. It is possible to newly saved corrected JPEG image in the editing RAW image
    * It takes more time to save the image when [Lens correction] is set to ON. Initial setting is OFF.
    *The [Lens correction] may not apply depending on using lens or setting.

    Can non-PENTAX interchangeable lens be used?
    Not recommended.
    We assume no responsibility or liability for damage resulting from the use of lenses made by other manufactures.

    Are there any precautions that should be observed when using SD (SDHC) Memory Cards?
    Please observe the following precautions.
    • Card that are unused or that have been used on other devices, such as another camera or a computer, must first be formatted on the PENTAX K-x.
    • Do not remove an SD (SDHC) Memory Card or turn the camera off while you are recording data or playing back images or audio, or while the camera is connected to a computer via a USB cable.
    • Do not bend an SD (SDHC) Memory Card or subject it to violent impacts. And do not leave cards in locations where they will be exposed to water, moisture, high temperatures, condensation, dust or strong magnetism is generated.
    • Avoid using or storing the card where it may be exposed to static electricity or electrical interference.
    • If a card is left unused for a long period, it may no longer be possible to read the data stored on the card. Important data should be backed up regularly.

    <Battery and Power sources>
