I sometimes have the same problems with macro pictures. Unfortunately, I do not have money for a macro lens right now, but there is a trick my first photo teacher taught me. You take your regular 35mm lens and take it off the camera. First you have to set the aparture and shutter speed and get the focus right, but after that turn the lens around. When you have the front of the lens touching where the back of the lens normally is, when you take the picture, it should come out clearer. Almost as if you were using a macro lens.
