|
Why is ISO sensitivity form 200? |
|
The CCD for using *istD is intended to exercise the best performance with equivalent of ISO sensitivity 200. If forcedly reduce at equivalent of ISO sensitivity 100, it can not get good image quality. |
| |

|
What is “the Sensitivity Correction” in Custom Function? |
|
Automatic sensitivity correction when exposure is out of range.
If object of shooting is too bright or too dark for setting Sensitivity value or setting shutter speed
does not couple with aperture value or setting aperture value does not couple with shutter speed, the camera automatically adjust exposure by either increase or decrease the Sensitivity value.
• Range of increase or decrease Sensitivity.
Initial setting: from 200 to 1600.
If change Sensitivity range to Wide 200 -3200 by custom function: from 200 to 3200.
Correction step: 1 EV
Sensitivity Correction will perform with following condition.
* Aperture — priority mode: outside of shutter speed
between 1/4000 to shutter speed for hand held camera. (The inverse of the focal
length)
"Although there are individual differences among photographers, in general the shutter speed for hand held camera is the inverse of the focal length. For example, 1/75 of second when the focal length is 75mm, and use 1/150 of second when it is 150mm"
* Shutter — priority mode: outside of range between minimum aperture to full open aperture.
* Program mode — outside of shutter speed between 1/4000 to shutter speed for hand held camera. (The inverse of the focal length) and outside of range between minimum aperture to full open aperture.

|
Can all 35mm interchangeable lenses be used? Is there any problem for performance? |
|
<functional compatible>
Basically, usable lenses that without limit for exposures are FAJ lenses, lenses
that have an aperture A (Auto) position and DA lens which is planning to sale.
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.
<Descriptive compatible>
We had shooting test from various perspectives regarding current product of 35mm
lenses and medium format lenses. In result, we have decided that all lenses are
descriptive compatible lenses.
However, each lens has different descriptive properties.
By changing the photoreceptor from film to CCD, there are the different descriptive
properties lenses from the use of film. |
| |
Back to Top |
|
Why there is limit for functioning when using non-A position lenses. |
|
For conventional camera, when rotate aperture ring, angle
of rotation is mechanically inputted to the camera and aperture value is read
into the camera.
*istD does not have such mechanism therefore, can not set the aperture value mechanically
by rotate aperture ring. To set the aperture value, set the aperture to the A
position and set the mode dial to Av and select the aperture value with the Av
dial. |
| |

|
Can non-PENTAX interchangeable lens be used? |
|
Not recommended. When assume no responsibility nor liability for damage resulting from the use of lenses made by other manufactures. |
| |

|
When using built — in flash, can flash amount compensation be used? |
|
There is no individual flash amount compensation function. However, when using auto bracket with built — in flash, auto bracket exposure can be changed only flash amount. |
| |
Back to Top |
|
When using external flash, can flash amount compensation be used? |
|
When using auto bracket with external TTL flash, auto
bracket exposure can be changed only flash amount.
When using AF360FGZ with the flash amount correction function (-3EV - +1 EV),
the flash amount can be compensating individually. |
| |

|
Can ring light flash AF 140C be used? |
|
Yes. However, if taking picture under special condition such as oral picture, some times not satisfying for result. In that case, use the instant review or playback display to confirming result of image.
|
| |

|
Can take the picture while looking LCD monitor? |
|
No. mainly 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. |

|
Can the movie Picture be used? |
|
No. The type of CCD does not support for movie picture.
If using the bulb mode and keep to catch the light to CCD, even so camera cannot
take the movie Picture. |
| |

|
What is the RAW data? |
|
The RAW data is “raw” data that is recorded
data before carry out image data processing for captured data.
When taking a picture, firstly the light of CCD caught is converted into electronic
signal.
This electronic signal is carried out image data processing to edit image data
then image data is recorded. This recorded image data is JPEG or TIFF. On other
hand, the Row data is directly recorded “raw” electronic signal before
carry out image data processing.
The Row data which is not carry out image data processing, if forward to the computer
as it is, can not see as image with regular software. Therefore, the image data
processing is necessary with software [PENTAX PHOTO Laboratory] which is packed
with the *istD camera.
But when playing back image on the LCD monitor of camera, the row data which is
before carry out image data processing can be displayed. Also when playing back
image on the TV monitor with connecting Video cable, it can be displayed. |
| |
Back to Top |
|
What is the advantage for taking picture
with RAW data? |
|
The RAW data is “raw” data that is recorded
data before carry out image data processing for captured data. Therefore, after
taking picture you can set the setting such as White balance,Contrast, Saturation
and Sharpness etc for each frame. (Non-Raw image must be set before taking (picture)
But for sensitivity, with increase amount of compensation, the image of quality
might be deterioration. Therefore, when taking picture, adjust exposure with correct
exposure as much as possible.
The Row data is 12 bit data with containing 16 times more information when compare
with 8 bit data of JPEG and TIFF. Therefore, it is possible to expressive with
various gradations sequence. |

|
Which type of RAW data for *istD, compressed
type or non compressed type? |
|
Non-compressed type of RAW data. It cannot save with compressed. |
