3.4 Finder Focus Adjustment
<Purpose>
The sensor focus point and the finder focus point must be the same.
<Specifications>
The center of the
×
(infinity) mark must be positioned within the 1.5 index line
widths of the index line as shown below.
<Tools>
•
Magnifier AD-S
•
Lens with focusing scale. Lens of 100 mm focal length or less is desirable.
•
General purpose 500mm collimator
<Adjustment>
1) Without the lens attached to the EOS-D60, adjust so the AF frame in the
center of the finder is using the diopter adjustment dial of the camera.
2) Attach the magnifier to the camera eyepiece and adjust the diopter of the
magnifier. (Adjust the diopter without the lens attached.)
- Dioptor adjustment method -
With the camera pointed at a wall having the high brightness and high
reflectance (such as white wall having EV12 or the light source of the shutter
testing equipment), adjust the diopter adjustment ring of the magnifier until
the AF frame is sharpest.
3) Attach the lens, and set the distance scale to
×
(infinity). (If the center of the
×
(infinity) mark is positioned within the 1.5 lines widths of the index line, it is
satisfactory.)
4) Shoot an object that is located at least 250m away (such as lightening rod or
chimney) and select the finder focus washer that gives the clearest view of the
object.
* When a collimator is used, select the focus washer that gives the clearest view
of the collimator scale.
Perform the Finder Focus Adjustment only after the FFD Adjustment
is completed.
