    Yes a smart answer would be welcome but it's just occurred to me that LG may add a manual focus ability in a future update, or a third-party app may become available.

    I know the laser works with third party camera apps. I tried a few just to see. Hmm.

    Okay, I meant if the laser failed, manual focussing could be used if that becomes possible...better than nothing.

    I just tried covering the laser with a finger and it seemed to focus okay.

    But if your camera fails, your laser focus will be useless.

    Can you actually see the laser? I've not tried...Just curious now to know if it even is working.

    I believe it's infra-red. But even so I wonder whether it might just be visible in fog.

    I remember seeing somewhere online that someone was able to see the laser using some kind of filter. I wonder if the laser can be used as a measuring device.

    You cannot see it with the naked eye. A webcam or any other video camera can pick it up using a filter, though.

    Interesting. I don't think the camera would stop completely. I think it would just take longer to focus than it would with the laser.

    It's kind of like on a camera. It shoots our a red infrared light to help focus. Without that, it would constantly try and focus.

    In the days of film photography, they said that if you looked directly at an infra-red flash, you could just see a red glow.
    But yes with fog, I suppose if anything the water particles would cause a loss of energy and convert the light to an even lower frequency.

    Unofficial Android Forums Health Warning: Don't look into your infra-red focussing aid to see if you can see the beam of pretty light. Also, if there's fog, don't go outdoors, you mighty get a nasty chest infection.

    I don't think its that type of laser. Just like if you try and take a picture of a plain, it won't blind them. It's just for quick focusing.

    I think the IR laser is for close subjects only. If reflected from a distant subject, the beam would surely be so scattered that the device would just register a null result, and assume a distant focus setting.
    Because IR, it would be invisible and therefore harmless to pilots of aircraft.
