Caution ! Dynamic AF versus single point AF... !
Jan 13, 2013

When reading some of the threads I realise that some people dont know the difference

between dynamic AF points and single AF points.....

When your camera is set to 9 or 21 or 51 or the focus point you select is only a bias not excactly the point it measures at....

If a point next to it has better contrast or if the camera figures out its better it biases towards that

or in most cases it uses the selected point plus interpolation like matrix metering uses the full frame to evaluate focus...

IF YOU WANT ONLY 1 focus point you MUST use only single AF (setting with an "S" )at AF-C or

AF-S which only has the S setting and automatic !!
