How do I clean a A70 lens? If I accidentally used the wrist strap and touched the lens... I found a small mark left by the contact (it's blue in colour..) will it affect the picture output?? Will using a lens cleaning cloth etc remove it?
Oh, i'd recommend that you buy a Lens pen. It's like a pen, except you have brush bristles on one end, and a cleaner on the other end. In such cases, i would use the cleaner and clean the lens. then brush off the remanents.
