First of all live focus picture is taken using telescopic camera so object will always appear close. A distance of about 1.5m = about 5 feets is recomended for this mode and it doesn't works on too far objects more than about 10 feet-12 feet depending upon lighting condition. If light is good you can shoot from a good distance & if its dim then you have to about 5 feet away from the object and you click on the body of the person the software will detect it for sure . Its bcoz of the lighting conditon that the software is not able to differentiate between objects at one go multiple attempts can lead to perfect focus . The more you click in live focus mode within the distance i told the more you will get to know about how to use it bcoz there is no exact guide for the lighting condition & i have been using it for more than a year now its awesome you will realise it once you get to use it properly . Here is one click of an object about 7 feet height and in dim lighting condition .
