Hi EveryoneI just got this camera a week ago,I love itI'm having trouble in the ""Creative zone,trying to figure out how to take a picture with a blurred backgroung.Specifically when I go to the dragstrip,I will take pictures of the cars in the pits ...
When i enter the mode setting,and change to continuous mode seting,it works fineWhen I turn off the camera,It reverts back to single shotIs this the way it is,or can I lock it in some way?ThanksJoe
