B+W Filters 55mm Close Up Lens NL3

Close-Up Series

The effect increases with the diopter number and the focal length of the lens. For shorter focal lengths in digital photography stronger close-up lenses are therefore recommended. The image scale describes the effect. A scale of 1 : 3 renders an object at a third of its original size on the film/sensor. Close-up and macro lenses are simple aids which are suitable in particular for three-dimensional objects (flowers) and pictorial photography, less for technical reproduction purposes. Sufficient stopping down increases the sharpness and the depth of field.

As clearly illustrated, the stronger the close-up lens, the closer you can get to the subject with the same distance setting and the larger the image you can obtain. A longer exposure time is not necessary. B+W close-up lenses can be combined, but for quality reasons and to prevent vignetting no more than two lenses should be mounted over each other. The values are simply added together.
