yes, if the focus is not correct i.e. pressing the shutter too quick, it will not take picture... also when you are too close to the subject, u will not be able to focus therefore cannot take the picture. also when the environment is too dark and u did not use the focus assist light, u also cannot take the picture... read you camera manual, there should be a FAQ section to tell you why u cannot take picture...作者: rexs 时间: 2010-10-1 11:21:05
