I'm sorry in advance for the newbish question. I've just received my E-M10 today and am still learning its menu system... I've noticed the IS is enabled whenever I use the touch screen to select my AF point. I already have the touch shutter disabled so I'm wondering why the IBIS engages just by selecting the focus point via touch screen. I know that the IBIS engages because I hear it. The sound emitted can be described as a static sound. How do I disable this so the IS is engaged only when half pressing the shutter? Thanks in advance.
