Has anyone else noticed the grip side of the OM-D getting hot immediately after shooting a few brackets and/or chimping? Not like it's too hot to touch, but a definite increase in temperature to "warm". I carry my OM-D by the grip (with wriststrap), so that may be adding to it, but definitely can feel an increase in temperature from when the camera is off or asleep. Note: I don't have any add-on grip attached to the camera. This is the "bare-bones" (silver) body I'm talking about. Anyone else notice this? Or am I having a problem? I have not experienced any operational glitches (knock wood) so I'm hoping that this is normal. Thanks!
