This extension tube is used with OM-System lenses to take close-ups of flowers, insects, and other small objects as well as for copying documents, maps, charts, etc. The focusing and viewing accuracy of the OM-System is of particular value in this type of photography.
This 14mm bayonet mount extension tube can be used with OM-1 standard lenses either singly or in combination with other extension tubes to provide seven different extension lengths. When all three tubes (each sold separately) are used in combination with the ZUIKO 50mm F1.8, you can achieve a life size magnification with a lens-to-subject distance just over 6.8cm (2 11/16″).
OM-System macro lenses, optically optimized for best performance at specific magnifications, can be used with extension tubes to further enhance your macrophotographic ability with the OM-1 camera.
