Subject : Distribution of “ K10D FAQ”
We are distributing the “K10D FAQ”. The FAQ is based on the most received questions
from Japanese customers, so we believe it is useful for your service section.
PENTAX DIGITAL CAMERA
Q: What is the magnification and the filed of view of the Viewfinder?
A: Magnification: 0.95x (with 50mmf/1.4 lens at infinity) Field of view: Approximately 95%
Q: How long is the finder eye relief?
A: Approximately 21mm
Q: What is the size and resolution of the LCD monitor?
A: 2.5 inch [TFT color LCD] with backlight and 210,000 pixel resolution
Q: Can the brightness of LCD monitor be adjusted?
Q: What is the filed of view of the LCD monitor?
A: Approximately 100%
Q: Can take the picture while looking LCD monitor?
A: No. The reason is mechanism of Single Lens Reflex Camera.
For take the picture while looking LCD monitor, the CCD needs to catch the right all the time for taking the picture while looking LCD monitor such as compact digital camera.
On the other hand, Single Lens Reflex Camera has mirror at the front of CCD for conducting light through the viewfinder. The CCD catches the light only shutter is opening.
Q: What is included in the K10D kit?
A: The K10D kit includes the following: K10D camera, Hot shoe cover Fk, Eyecup FP, ME finder cap, Body mount cover, USB cable (I-USB17), AV cable (I-VC28), Software CD-ROM (S-SW55),Strap (0-ST53), Rechargeable Lithium-ion battery (D-LI50), Battery charger stand (D-BC50), AC plug cord(D-AC2J), K10D Product Manual PENTAX PHOTO Browser 3/ Laboratory 3, Operating Manual, Warranty.
Q: Are there any necessary accessories other than what is included in the kit?
A: Yes, Secure Digital (SD memory)/SDHC card
Q: Is there an exclusive camera case to the K10D?
A: Yes, 0-CC55 is available as optional.
Q: Can the voice be recorded?
Q: Is there an interchangeable focusing screen available?
A: Yes, Optional AF Scale matte and AF Divided matte is available.
Q: Is there any measure to protect the Dust on CCD?
A: SP coating on the low pass filter is effective to prevent dust from sticking to the CCD and furthermore, Dust Removal function will shake dusts off.
Q: Is K10D deigned as weather/dust resistant camera?
A: Treatment for weather/dustproof is made on each dial button and body. So you can use it in the light rain or dust.
Q: What is the recording format?
A: You can choose either from JPEG, which has high versatility or RAW, which you can arrange after shooting. Also you can shoot both RAW and JPEG together. It is possible to do basic development of RAW in the camera
Q: What is “In-camera RAW development”?
A: You can change RAW image into JPEG in the camera and save it as JPEG. It is possible to modify image quality, sensitivity etc. So you can print the image by connecting to printer directly if you develop RAW to JPEG in the camera.
Q: Is AF assist light available?
A: Yes, the built-in flash will discharge automatically several times, except when the camera is set at AF-C mode.
Q: The image tone can be selected Bright or Natural. What is the difference of each?
A: Bright: Bright Images are finished brightly, with high contrast and sharp.
Natural: Natural Images are finished naturally and suitable for retouching
Q: Can I view images on a TV?
A: Yes. By using the AV cable (I-AVC28), you can capture and play back images on a TV that has a Video-In port.
Note: Make sure that both the TV and the camera are turned off before connecting the cable.
■ Shake Reduction
Q: What is the difference between K100D’s SR?
A: By equipping stronger magnet and coil, it has improved maximum compensation effect and reliability of this function.
Q: How much compensation (in shutter speed steps) can I expect?
A: It is 2,5 to 4 shutter speed step effect.
*The effect is not equal depending on the focal length, distance to the subject, shooting circumstance, and individual technique.
It is generally said that the slowest shutter speed to avoid hand blur is 1/focal length. In the case of APS-C size sensor (such as K10D), please consider the focal length as 1,5 times longer (That is, the focal length in 35mm format)
If you take an example of 100mm lens, it is equivalent to 150mm lens in 35mm format. The slowest shutter speed in general is 1/150 sec. So you may expect the effect of shake reduction at 2,5 to 4 steps slower shutter speed than 1/150.
*If you use DA・D FA・FA・FA J・Ｆ lens, the focal length information is automatically acquired by thecamera.
If you use lenses other than the above, please set the focal length in the menu of shake reduction.
*When using a lens without the s position on the aperture or with the aperture set to a position other than the s position, set [Using aperture ring] on the [A Custom Setting] menu to [Permitted].
Q: Which focal length should I set when using MF zoom lens?
A: Please set the closest focal length you will actually shoot.
Q: Are there any lenses which SR is not effective?
A: No, you can expect the SR effect with all the PENTAX lens attachable.
Q: Can non-PENTAX interchangeable lens be used?
A: Not recommended. When assume no responsibility or liability for damage resulting from the use of lenses made by other manufactures.
Q: Does SR work with the non-PENTAX interchangeable lens?
A: The function will react, but the effect is out of our guarantee.
Q: Do we recommend SR is always ON?
A: Yes, we recommend ON when you shoot with holding the camera by hand.
Q: Why is there SR switch?
A: To make it switch arbitrarily according to the shooting condition.
Q: Does battery life change depending on the SR switch ON or OFF?
A: No it does not.
Q: Can the SR function works when setting on Bulb mode?
A: No, The Shake Reduction function automatically turns off in the following situations. When using self-timer, 2 sec. self-timer, remote control shooting, 3 sec. delay shooting, Bulb shooting, or wireless mode with an external flash
Q: Does SR work at slow synchronization of flash?
A: Yes it does.
Q: Can the effect of the SR be confirmed in the finder?
Q: Can the effect of the shake reduction be confirmed before takes a picture like Optio A10/A20?
A: No, because K10D’s Shake Reduction works only the moment shutter is released.
Q: Can all PENTAX 35mm interchangeable lenses be used?
A: Basically, usable lenses that without limit for exposures are DA lenses and FAJ lenses, lenses that have an aperture A (Auto) position. When changing custom function to use non- A position lens,
Medium format lens and screw mount lens with using mount adapter can be use but there is limit for usable function as follows.
