Macrophoto Group Close-up Lenses 49mm f=40cm / 55mm f=40cm
| Summary | Main Characteristics | Notes - Related Units |
| They are auxiliary lenses to screw into standard OM System lenses for close-up work. | With the close-up lenses, the minimum focusing distance of the standard
lenses can be reduced from 49cm to 19cm, at which distance the subject area will be
12x8cm. These close-up lenses permit the automatic diaphragm operation of the standard lenses to facilitate a bright image observation through the fully-opened aperture and exposure adjustment. |
The respective diameters of these filter mounting threads are 49mm
(specially intended for the 50mm/F1.2, 50mm/F1.4 and 50mm/F1.8) and 55mm.(specially
intended for the 55mm/F1.2). Use of other lenses with a 49mm or 55mm thread is also possible. Since the depth of field is extremely small in close-up photography, the lens aperture should be stopped down between F8 and F11 to obtain sharp image definition. Recommended to use a focusing stage, tripod and shutter release cable to eliminate any vibration that may affect a picture. |
