Hi, First, make sure that the camera is not in Macro (close up) mode.
To set a good reference point reset the camera to the default settings.
Press the Menu button At the top there are tabs. Select (the 3rd wrench icon)
Arrow Down to Reset Arrow
Right once Press Menu/OK
Select Yes and press Menu/OK
Allow the process to complete
Please let me know the result.
Next, the one thing that even experienced photographers miss is that a single small spot or smudge on the lens can cause the problem that you are having. Carefully clean the lens again and look for any scratches. Depending on the environment that you are shooting in, a haze can build up on the lens and cause incorrect readings and the shutter will not release until accurate focus has been achieved.
Please keep in mind that my diagnosis & solutions provided are directly dependent on the accuracy of your description of the problem. As with any "do it yourself" fixes, success is a "team effort", since I can't see or touch the camera, and relies on the customer's manual dexterity and ability to follow the instructions well.
