You want to use the Super Macro Lens when the subject is smaller than about 2-3 cm across. Attaching the diopter will allow you to magnify the scene and to move your camera slightly closer to the subject. A good viewfinder is must. Try to compose your photo with your camera on the same level as the subject (or slightly under the subject), with the focus on the subject’s eye (or rhinophores).
