[Supplement]
If focus is NG, There is possibility with following factors.
AF focus position error or adjusting error. (Confirm AF focus position (FI) : NG)
Adjust positioning of 1
st
and 2
nd
Mirror, AF adjustment by programmed software (Part of SLR mechanism)
Height of the CMOS Base Plate Support Pillar is NG
Confirm with disassembly, Adjust with washer and re-assemble.
Related parts: Mount ring, Front, Front Housing Block, body main plate (pillar installing parts), and other
frame (A3, A4, A6)
If camera is OK, There is possibility for trouble with the lens.
11-12. Confirmation of SR mechanism
Method for confirmation is the same as 76830(K10D)
[Required equipment]
PC, Battery (AC adaptor), USB cable, F/FA50mm lens, SD card (for taking
picture), Image viewing software (For Example :ACDSee
TM
, Adobe Photo shop or other)
①
Attach FA50mm lens to the camera and set aperture ring at A position.
②
Set the camera as follow.
Exposure Tv mode, Focus mode SW: AF, Focus point: Spot, Drive mode: single frame
White balance :AWB,
Recorded pixels: Default setting, Quality Level: Default setting
③
Set Tv8 (1/8sec) --- It is equal to approx 3.5 step.
④
The distance of the camera is set from subject to 2m.
⑤
Set the SR switch to OFF and capture 10 images. (Camera is set on Horizontal/Vertical position)
⑥
Set the SR switch to ON and capture 10 images. (Camera is set on Horizontal/Vertical position)
[CAUTION]
Release the shutter about 1 second later after hand shake indication is ON in the view finder.
⑦
Open the image with Image viewing software.
⑧
Compare the images (SR ON/ SR OFF) and confirm that whether SR function is effective.
[CAUTION]
It may differ depending on the condition of holding camera.
Confirmation of SR mechanism (When use different type of focal length)
The shutter speed of prevention for shaking is calculate with [1 / focal length of the lens]
For instance, if the focal length is 200mm: 1/ (200 x 1.5) = 1/300
* Size of picture for digital camera is 23.5 x 15.7mm and it is about 1.5 times when converting it into the
focal length of 35milli-size camera.
①
Calculate the shutter speed of prevention for shaking as above.
For instance, if the focal length is 200mm: 1/ (200 x 1.5) = 1/300
②
Converts above shutter speed to three step down. (If necessary, four step down)
Ex: 200mm
equal to approx
1/30 (Three steps)
③
Set Tv 30.
④
Follow the procedure of 10-5
④〜⑧
.
[CAUTION]
The effect of the shake reduction is influenced by the focal length of the lens and the object
distance and effect might not become visible in the short distance (D-FA50mm Macro 0.4m), also an enough
effect might not become visible at the low temperature.
