In addition, the Dust Removal function can be used to shake any dust off. The camera also features a Dust Alert function that detects any dust collecting on the image sensor.

What is the ‘Dust Alert‘ function?

It is a function that detects any dust collecting on the surface of the image sensor and alerts you about that. The Dust Alert function clearly displays the location of the dust to make it easier for you to clean the image sensor.
The following conditions are necessary to activate the Dust Alert function.

The lens used is a DA or FAJ lens, or a DFA, FA or F lens that features an A (Auto) position on the aperture ring.
If the lens features an aperture ring, it is set to the A position.
The focus mode lever is set to AF.

* If using the DR (Dust Removal) function cannot eliminate all the dust from the image sensor, please use the optional Image sensor Cleaning Kit O-ICK1. You can also contact a PENTAX Service Center for professional image sensor cleaning.

Is the focusing screen interchangeable?: Yes it is. The AF Scale Matte (LI-80) and the AF Divided Matte (LL-80) are available as optional accessories.

Can a Ref-converter A or M be used with the camera?: Yes.

Can an eyecup M or M II be used with the camera?: The Eyecup M II can be used with the camera; Eyecup M cannot.

Can a Magnifier Eyecup O-ME53 be used with the camera?: Yes. In that case the combined magnification will be approx. 1.12 times.

What is the "Bright/Dark Area" warning?: When this function is activated, areas in the image that are too bright or too dark and have lost gradation detail will blink on the monitor during playback and instant review.

What is the recording format of the images?: You can choose to record images in the versatile JPEG format or the high-quality and fully editable RAW format. You can also select JPEG+RAW and record in both formats. Pictures taken in RAW format can be developed in the camera and saved as TIFF or JPEG images.

What is the Sv (Sensitivity Priority) mode on the mode dial?: You can set the sensitivity to suit the brightness of the subject.
The shutter speed and aperture are automatically set according to the selected sensitivity to obtain the appropriate exposure.
* In Sv mode the sensitivity is always displayed on the LCD panel and in the viewfinder. The sensitivity can be adjusted in 1/2 EV or 1/3 EV steps.

What is the TAv (Shutter & Aperture Priority) mode on the mode dial?: You can set both the desired shutter speed and aperture to take the picture.
The sensitivity is set automatically so that the shutter speed and aperture selected will give the appropriate exposure according to the brightness of the subject. This mode is convenient to take reliable pictures even when the light conditions are changing from moment to moment.

What is the USER mode on the mode dial?

Several camera settings stored in advance to your preference can be retrieved and applied simply by setting the mode dial to USER.
Every time you turn on the camera with the mode dial set to USER, camera settings will return to their stored values. You can use this as a kind of “Reset to my preferences” function.

The following camera settings can be stored in advance.
(1) Exposure mode; (2) Flash mode; (3) EV compensation; (4) Exposure bracketing steps and number of pictures; (5) Drive mode; (6) Flash exposure compensation; (7) Extended bracketing steps and type; (8) Sensitivity; (9) Auto sensitivity adjustment range; (10) White balance; (11) Color space; (12) File format; (13) JPEG recorded pixels; (14) JPEG quality; (15) Expand dynamic range; (16) RAW file format.

What is the RAW+ button?: By default, images are recorded in both RAW and JPEG format when the button is pressed.
Using the menu you can customize how the change in file format will be applied.

*Even while taking pictures in JPEG format, you can save a scene you especially like also in RAW format.
*And vice versa - you can save an image in JPEG format even while taking pictures in RAW format.

Using the menu you can select whether the change applies to just one picture or if it is applied until you press the button again.

What finishing touches settings are included in the Custom Image function?

Select from the following finishing touches: Bright, Natural, Portrait, Landscape, Vibrant and Monochrome.
The default setting is [Natural].

What is Dynamic Range (D-Range)?

It is the ratio that indicates the light gradation expressed by the CMOS sensor pixels from bright areas to dark areas.
By using the Expand Dynamic Range function, you can expand the light gradation expressed by the CMOS sensor pixels, making it more difficult for bright areas or dark areas to occur in the image.

* The sensitivity can be set between ISO 200 and 3200. (ISO 6400 with Expand sensitivity)

What is Noise Reduction?

When you use a digital camera to take pictures with a long exposure or high sensitivity setting, image noise (image roughness or unevenness) becomes noticeable. This camera offers two noise reduction functions that can be used for different conditions: Slow Shutter Speed NR and High-ISO NR.

* Images shot with Noise Reduction take longer to save.

What is the Extended Bracket function?

You can save pictures with three different white balance, saturation, sharpness and contrast levels.
Unlike with Auto Bracketing, three images are saved with each shot.

What is the built-in RAW data development?

RAW data can be converted in the camera and saved in TIFF or JPEG format. Image quality and sensitivity can be adjusted.

Can I view images on a TV?: Yes. Connect the USB/Video terminal on the camera’s side to the TV’s video input terminal using the provided Video cable I-VC28. Make sure to turn off the camera and the TV while connecting the cable.

Shake Reduction (SR)

How effective is the Shake Reduction in terms of shutter speed steps?

The effect of Shake Reduction is equivalent to approx. 2.5 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 (like the K20D), 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.

* When using DA, D FA, FA, FA J or F lenses, the camera will automatically acquire the focal length information when you use Shake Reduction.
*When using lenses without the A (Auto) position for the aperture or with the aperture set to a position other than A, set [Using aperture ring] in the [C Custom Setting] menu to [Permitted].

When using lenses whose focal length information cannot be acquired automatically by the camera, set [Focal Length] manually in the [Input Focal Length] setting menu.

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.

Can non-PENTAX interchangeable lenses be used with this camera?: It is not recommendable. PENTAX will assume no responsibility nor liability for accidents, damages and malfunctions resulting from the use of lenses made by other manufacturers.

Will the Shake Reduction (SR) function work with non-PENTAX lenses?: The Shake Reduction mechanism will function but the effectiveness of the results cannot be guaranteed.

Would it be better to leave the SR function always on?: The camera features a Shake Reduction switch to easily turn off the SR function according to shooting conditions, for example when using the camera with a tripod.

What is the Shake Reduction switch for?: To easily turn off the SR function according to shooting conditions.

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?: No.
* The Shake Reduction function is automatically turned off in the following situations: When using the self-timer, 2-sec. self-timer, remote control shooting or 3-sec. delay shooting, when shooting in B (Bulb) mode or when using wireless mode with an external flash.

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?: No.

Can the effect of the Shake Reduction function be checked before taking the picture, like in theOptio A30 or A40?: Using Live View the effect can be checked before taking the picture.

PHOTO Laboratory 3 does not have a (Premium) image quality setting. When viewing in PHOTO Browser 3 JPEG images developed using the highest image quality, the quality appears only as Best.: In PHOTO Laboratory 3 image quality can be set to one of 5 levels; in the camera it can be set to one of 4 levels. The image compression engine that the software uses is different from that of the camera. Actual compression rates will be different even if the image quality display is the same.

Does the RAW data of an image recorded with the Expand Dynamic Range function reflect this when using PHOTO Laboratory 3?: Yes. The expanded dynamic range of an image is incorporated into the RAW data so you will see this even when developing the image using PHOTO Laboratory 3.

Are the [Fine Sharpness] and [High-ISO Noise Reduction] settings reflected when developing the RAW data using PHOTO Laboratory 3 in full automatic mode?: The image processing engine that the software uses is different from that of the camera so these settings will not be reflected.

Can Live View be used in combination with REMOTE Assistant 3?: No.

<Connecting with a Printer>

Does the K20D support P.I.M. (PRINT Image Matching™) and Exif Print (Exif 2.2)?: JPEG images shot with this camera support both. RAW images do not.

Does the K20D support PictBridge?: Yes it does. Print mode can be selected from Single Image, All Images or DPOF Autoprint.
The following print settings can be set: Date imprint (on/off), paper size, paper type, print quality and border status. Depending on the printer used, some print settings may not be applied.

<Troubleshooting>

The [Dust Alert] function cannot be selected.: The [Dust Alert] function is available only if all preconditions are fulfilled. Click here for the details about the preconditions.

During Live View a noise can be heard from the camera. Is this a malfunction?: A faint operation noise may be heard when using the old lenses such as smcP-F. This does not indicate a problem. The symptom is limited to Live View only and will not affect the image shot or the effectiveness of the Shake Reduction function.

The built-in flash is discharged continuously. Is this a malfunction?: The AF illuminator is being activated.
If you press the shutter release button halfway when the built-in flash is up in the AF.S (Autofocus/Single) mode and the object is dark, the built-in flash is discharged automatically multiple times to make the autofocus operation easier.

* Not activated in AF.C (Autofocus/Continuous) mode, MF (Manual focus) mode or when the built-in flash is retracted.

The initial setting of the camera is in a language other than English. How to change the language setting?: The initial settings screen is only displayed the first time the camera is turned on. If the initial setting was incorrect it will be necessary to change each setting individually.

The message “Memory card full” appears.: The SD (SDHC) Memory Card is full and no more images can be saved.
Replace it with a new SD (SDHC) Memory Card or delete unwanted images.
You may be able to save new images by changing the file format (RAW/JPEG), the JPEG record pixels (14.6M/10M/6M/2M) or the JPEG quality (•••) settings.

The message “Memory card error” appears.: The camera cannot correctly recognize the SD (SDHC) Memory Card. Image capture/playback is impossible. You may be able to view the content of the Memory Card on a computer.

The message “Card not formatted” appears.: The SD (SDHC) Memory Card you have inserted is unformatted or has been formatted on a computer or other device and is not compatible with this camera. Use the SD (SDHC) Memory Card after formatting it with the camera.

The message “Card locked” appears.: The write-protect switch on the SD (SDHC) Memory Card is set to the “Lock” position. You can still operate the menus, switch modes and play back the images.

How should I attach the K-mount Adapter for 645 lenses?

You may not be able to attach K-mount Adapters for 645 lenses due to the direct contact with the locking screw. To attach the K-mount Adapter to the K20D you will need to align in advance the position of the mount unit.

* After loosening the locking screw of the K-mount Adapter you can rotate the mount unit; click-stops are located at 90-degree intervals.

Attaching the adapter:

Position the K-mount Adapter so the red dot mount index on the 35 mm side of the adapter is opposite the locking screw. Attach the K-mount lens cap to the K-mount Adapter.
Loosen the locking screw, rotate the K-mount lens cap so the red dot mount index is on the opposite side and tighten the lock screw.
* Avoid holding the mount unit directly with your fingers.
Remove the K-mount lens cap from the K-mount Adapter and attach the adapter to the K20D.
After attaching the K-mount Adapter, the locking screw should be at the bottom. Loosen the locking screw, rotate the K-mount Adapter 90 degrees counter-clockwise and tighten the locking screw.
Mount the 645 lens to the K-mount Adapter.

Removing the adapter:

To remove the K-mount Adapter loosen the locking screw and rotate the adapter so the locking screw is found at the bottom. Tighten the locking screw and then remove the K-mount Adapter.

* Set the lens to maximum aperture before focusing. When shooting, set the desired aperture value. (minimum aperture light metering)
* When the aperture ring of 645 lenses is set to the A position, the minimum aperture will be used.
* The lens shutter of 645 LS 75 mm, f/2.8 lenses and 645 LS 135 mm, f/4 lenses cannot be used.

The [Input Focal Length] function cannot be selected.

The [Input Focal Length] setting menu does not appear when using lenses that support the automatic acquisition of lens information such as focal length (for example DA, D FA, FA, F lenses) because [Focal Length] is set automatically.

None of the [Input Focal Length] setting options matches the focal length of the lens.: Use the closest setting to the actual focal length of the lens used. (For example, select [18] for a 17 mm lens or [100] for a 105 mm lens.)

What [Input Focal Length] setting should be selected when using MF zoom lenses?: Enter a focal length that is closest to the focal length that will be used for the actual shooting.

Are there any restrictions on the built-in flash depending on the lens used?

When using the built-in flash, vignetting may occur depending on the lens used and shooting conditions. We recommend taking a test shot to confirm this.
* The flash will fire at full intensity, without flash output control if [Using aperture ring] in the Custom Setting menu is set to [Permitted] but the aperture ring is set to a position other than A, and when using either lenses without an A position in the aperture ring or soft lenses.

The following lenses cannot be used with the built-in flash due to vignetting.

DA Fish-eye 10-17 mm F3.5-4.5ED (IF)
DA 12-24 mm F4ED AL
DA 14 mm F2.8ED (IF)
FA300mm F2.8ED (IF)
FA600mm F4ED (IF)
FA250-600mm F5.6ED (IF)

The following lenses can be used with the built-in flash under certain conditions.

F Fish-eye 17-28 mm F3.5-4.5
Can be used at a focal length of 20 mm or longer.
DA 16-45 mm F4ED AL
Can be used at a focal length of 28 mm or longer.
Can be used at a focal length of 28 mm if the shooting distance is at least 1 m.
DA16-50mm F2.8ED AL (IF) SDM
Can be used at a focal length of 20 mm or longer.
Can be used at a focal length of 20-35 mm if the shooting distance is at least 1.5 m.
DA18-250mm F3.5-6.3ED AL (IF)
Can be used at a focal length of 35 mm or longer.
FA28-70mm F2.8AL
Can be used at a focal length of 28 mm if the shooting distance is at least 1 m.
FA Soft 28 mm F2.8, FA Soft 85 mm F2.8
The built-in flash will always discharge at full intensity.

* As of December 2007.

The [AUTO] sensitivity cannot be selected.: When the exposure mode is set to M (Hyper-manual), B (Bulb) or X (Flash X-sync speed), the sensitivity cannot be set to [AUTO].

The shutter speed and aperture value indicators blink in the viewfinder.: If the subject is too bright or too dark, the shutter speed and aperture value will blink in the viewfinder and on the LCD panel. Change the shutter speed and aperture value. When the indicator stops blinking, you can take the picture with proper exposure.
* Use an ND (Neutral Density) filter if the subject is too bright. Use the flash if it is too dark.

Can the provided application software be used with *ist D series or with the K10D, K100D, K100D Super cameras?: PENTAX PHOTO Browser 3.5 and PENTAX PHOTO Laboratory 3.5 provided with the K20D and K200D, can be used also with those other cameras.
Using the software version 3.5 RAW data development is available also when using *ist D, *ist DS, *ist DS2, *ist DL, *ist DL2, K100D, K100D Super and K10D cameras.
RAW data development of images shot with the K20D is not available when using previous software versions (PENTAX PHOTO Laboratory 1.0 to 3.12).
