B+W NL-10 Macro
The +10 diopter of this B+W macro lens goes well beyond the normal range for close-up lenses. You can access the real macro range without an expensive specialized lens and reproduce the very small as huge (approx. 1 : 2 to 1 : 1.5). An aperture of f/8 or f/11 is recommended for good sharpness especially into the corners. It is also ideally suited for digital cameras because of its high power.
