Appendix: Use focus assist
BC840 includes Focus Assist functionality to achieve optimal image quality. Focus Assist can
be used from the Video page but also from the back of the camera body. The latter may prove
useful when setting the focus without a monitor.
To use Focus Assist from the webpage
1
On the Video page, select the Image tab.
2
Under Camera setup, select Focus assist enable.
The focus level is indicated by the blue Focus assist meter bar. The meter is also
overlaid over the image as a vertical white bar.
3
Aided by the feedback from the Focus assist meter, adjust the focus on the lens.
The greater the detail in the scene, the higher the number on the Focus assist meter.

Assist has not registered a maximum sharpness value yet.

Slowly turn the focus ring of the lens until the LED shines red.
