T-Genius Lens Back Focus


Set Aperture to fully open.

Zoom in fully, focus with the software controls.

Zoom out fully.

If the image goes out of focus then the back focus is wrong.

The TGENIUS back focus controls are on the side of the lens.


Loosen the lock screw slightly with a 1.5mm hex driver. Then adjust the back focus with the flat head screwdriver until the image is in focus.

When the focus is correct tighten the locking screw again.


Zoom in, adjust focus in software, zoom out. Image should stay in focus. If not the repeat the above.
