Flange Back Adjustment

1.Preparation

2.Flange Back Adjustment

DZOFILM will check and adjust ﬂange back distance of all CATTA 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;
