need help on what shop specializes focusing issues. i used to enjoy the IQ of my canon40d and 18-55mm kit lens but lately, i noticed its getting a little blurry. even using a flash and setting the shutter speed to more than a hundred, i still dont get sharp images. i read something about back or front focusing issues and its workarounds but i just dont have the time and capability to do it.
thanks in advance to those who will pitch their help.
