My TX100 seems to of developed a problem where the left part of the image is super sharp, but the right side is really blury. Meaning viewing is starting to become painfull on the eye. Is there any way i can remedy this fault ? It could be the lens on the front, but i bought a can of air to blow any dust of but it did not make much diffrence, im tempted to rub a cloth over the lense but feel it could make it worse. Any ideas ?
