Flange Back Adjustment - Hitachi KP-D5000 Operation Manual

Flange back adjustment

Flange back adjustment is needed after installation of lens or in
cases where focus cannot be obtained by normal lens focus
operation and focus is lost at the wide angle settings of a zoom
lens.
In such cases, open the lens iris (refer to page 39) and adjust as
follows.
1) Fixed focus lens
① Set the lens focus ring to infinity
② Aim towards an object at least 20 meters distant.
③ Turn the flange back adjustment dial to adjust the focus.
Please take care not to disturb the lens focus ring.
2) Zoom lens
① Aim towards an object at least 20 meters distant.
② Focus is adjusted by turning the focus ring. Loose
the lens mount screws. Set the lens to wide angle and
turn the flange back adjustment dial to adjust the focus.
Please take care not to disturb the lens focus ring.
③ Again set to telephoto and adjust the focus by
turning the flange back adjustment dial.
④ Repeat these steps until the focus is not suitable
for telephoto and wide angle.
⑤ Finally, tighten the lens mount screws.
Note
If an auto iris lens is used and the object distance is less
than few meters, due to focus length of lens, slight blurring
can occur at certain iris positions.
In such case, please refer to page 39[Lens open setting]
and set the lens to full open. At this time, AES is operated.

AES is a function to automatically adjust the electronic
shutter speed according to the amount of incident light
and keeps the image level constant.
