There are several ways to make you macro photos sharp. Getting blurry photos is the biggest issue photographers have when shooting macro. Camera movement and missed focusing are the two biggest obstacles to overcome. USE A TRIPOD. This will prevent your camera from moving during the exposure and will keep the focusing distance between your lens and subject constant.  SMALLER APERTURE. Using a smaller lens opening (larger f/stop number like f/11 or f/16) will give you a larger range of sharp focus. INCREASE LIGHTING. Adding light to your subject will allow you to use a faster shutter speed and/or a smaller aperture to get sharper macro photos.
