.Preparation
.Flange Back Adjustment
DZOFILM will check and adjust flange back distance of all CATTA ACE lenses
before shipping. But the flange back distance might have slight difference among
different cameras. To achieve the best performance and match different cameras,
flange back adjustment is needed.
Step One : Rotate the zoom ring to the longest focal length, and rotate the focus
ring until the image to its clearest, mark down the focusing distance S;
Step Two : Rotate the zoom ring to the widest focal length and rotate the focus ring
until the image to its clearest, mark down the focusing distance S;
Step Three : Compare the difference between S and S. If S<S, then need to add
shims; otherwise decrease the shims,
Note : The shim adjustment is evaluated on the angle between S and S. If the
angle is bigger, then need to change more shims and vice versa.
Step Four : Repeat step until S=S.Then it means the lens in under parfocal.
Step One : Ready your subject. You can use a "Star Chart", or other high-resolution
black-and-white objects;

Φ
Rotate the focal length to mm, and focus till the image is at its sharpest, the focusing
distance mark is .m S. And then rotate the zoom ring to mm, re-focus to the
image at its sharpest, current focusing distance mark is .m (S). S<S. According to
the sheet below, add .mm shims on the lens mount and double check. At this time,
both mm and mm focus at the closest under . focus mark.That means this lens is
under parfocal.
