The most common mistake when using the macro lens is positioning the camera too far away from the subject. Ideally, the macro lens should be about 1/2 inch to 2 inches (~1cm-5cm) away from the subject of the photograph. The macro lens allows your camera to focus on subjects that are much closer and, as a result, it can’t properly focus on distant subjects.
Also, because the macro lens magnifies your subject significantly, it will pick up slight hand movements which can cause motion blur in photographs. This makes keeping the camera stable especially important when using the macro lens. Using a tripod can be very helpful toward this goal, but great results can still be achieved by holding your hands extra steady while shooting with the macro lens.
