1 Scope and field of application
This International Standard specifies a standard series of diameter sizes for the front part of a lens barrel (dimension B in the figure)
and a standard series of thread sizes (dimension A in the figure) for the same front barrel. It is applicable to camera lenses and lenses
for enlargers ahd similar equipment. If is mainly intended that these standard sizes will simplify the production and storage of such
auxiliaries as screw-in filters.
2 Dimensions
The dimensions shall be as shown in the figure and given in the table.
