With extremely high +10 diopter power this close-up lens goes beyond the normal scope. Its high refraction is ideal for the short focal length of digital photography.
Even at a focal length of just 50 mm you enter the macro range, with an image scale of approx. 1 : 2. To increase (depth of) focus, stopping down by three f-stops is recommended. If graduated sharpness is part of the image concept, open apertures can also be used.
