B+W 49mm BIFO 2 (+3.5) Filter Description


The BIFO lenses allow simultaneous focusing on distant and near objects in the same frame. Approximately 1/3 of the 360 degree surface of the Bifo attachment works as a close-up lens. The +2.5 diopter (Bifo 1) and +3.5 diopter (Bifo 2) allow ocusing on a close object in the 0.40m and 0.28m, respectively (15.75 in and 11 in.). The remaining part of the attachment has no refractive power, thus, the reproduction properties of the lens (normal focal length to wide angle) remain unchanged in the other part of the image field.
