Have had my E-M5 a little over a week now and still trying to learn the system. A question for those of you more experienced and familiar with it... Compared to my Nikon D7000 - and any other camera I've owned - there is a rather lengthy delay after I press the shutter button and when the exposure actually occurs. During that time a lot of movement on the part of my subject, such as my grandson, can occur. Is this normal? Like many features of this camera, can this be reprogrammed to operate faster?
