Reduction Rings

Rings DISCOUNT for adapting filters with a diameter less than that of the objective.
By convention, the first dimension indicates the diameter of the objective, that of the second filter, eg. : 77 mm - 72 mm.
Fits beyond the objectives of the standard focal whose body is much larger than the front lens, such as certain macro optic or fixed focal lengths. In this case, there is no vignetting (a single T! Contrary to what is seen commonly written ...).
Product very good.
