(Click to jump to the website）
Note: About the shooting distance in Step Four:
① Tango Zoom 18-90mm needs setting at 1.5m or 7 ft;
② Tango Zoom 65-280mm needs setting at 3.5m or 11 ft.
Step Three : Repeat step One and Two until without moving the
focusing ring, the wide-angle end and telephoto end are both in sharp
focus and the focusing scales are accurate . This means the lens is
parfocal. Then tighten the headless screw on the flange back
adjustment ring in the clockwise direction to complete the flange back
adjustment.
Step One :
Ready your subject. You can use a "Star Chart", or other
high-resolution black-and-white objects;
Step Two : Attach the lens to the camera;
Step Three : Select the maximum aperture (wide open);
Step Four : Set the object 1.5m away from the camera sensor plane,
and adjust it to the center of the whole image.
