What does a SharpEye Macro Lens diopter mean?
SharpEye macro lenses sometime feature different diopter values. The difference between these lenses, featuring different diopters, is the degree of magnification and the minimum focus distance of the lens.
Generally speaking, the higher the diopter of a macro lens is, the more it magnifies the subject. Also, a higher diopter means a shorter minimum focus distance.
For example, a +8 diopter lens magnifies the subject more significantly and also enables shooting from a shorter distance between the camera lens and the subject when comparing to a +4 diopter lens. The macro effect, therefore, is more significant on the SharpEye +8 diopter.
Please take into consideration that in some cases, you might still prefer the +4 diopter lens because of the more subtle macro effect.
