Cleaning your lens will help your lens performing at its best, and this tutorial shows us how to do it properly. You will need: lens cleaning fluid, soft cloth, blower ball, and pencil. Start off by blowing air onto the lens and then dropping the cleaning solution onto the cloth. Rub the cloth into circles and start rubbing the lens gently. Now, take your pencil eraser and rub the contacts to remove any grease, then use the blower ball to remove any particles you see around the lens. Do this anytime you notice your camera lens is looking dirty, and it will keep it running at its best with no problems.
