Hi can someone help please. Have 2 canon 1D mark 4 ., tamron 150-600vc .. single focus point and not on servo the focus point is “double focusing”.., focus on subject the focus point then jumps to a point next to the center .. not every time but 40% of time .. I did find a function in menu that keeps focus point on .. so with the red square focus point it sometimes replicated over it and focus point in thumb nail on lcd screen .. where it shows where the point was.. in on subject but sometimes it jumps and remains on .. so there 2 red focus points ., and if the second point is moved to subject it show that on rear lcd thumb nail .. if not “recomposed “ it is off the subject resulting in out of focus image..same on both bodies and other 3 lenses do not react this way .. remain centered
