H&Y launches variable filter adapter ring for faster filter replacement
Recently, filter manufacturer HY has launched a series of new variable filter adapter rings with variable thread sizes, allowing users to install a screw-in filter to Multiple lenses of different sizes. Using the spring iris, the thread size of the transfer device can be changed by the rotating ring on the adapter to adapt to different lens sizes. This design allows a single rotating filter to be switched between lenses without changing the adapter ring.
It is reported that the core of the adapter ring is a set of “lens aperture blades.” Users can install filters and hoods through threaded screws. Due to different lens sizes, filter diameters are also different, generally between 37-95mm. The variable diameter circular threaded interface can be adapted to a variety of lenses. According to the manufacturer, the HY variable filter adapter ring borrows the working principle of the iris diaphragm and adds a thread on the edge of the blade to create a variable-size threaded interface. The filter adapter ring has three different specifications: 37-49 mm, 46-62 mm, and 67-82 mm.
The manufacturer said that these runners are made of 6063 grade aluminum for construction, which reduces weight and also has greater strength. It is reported that the 67-82mm ring has a net weight of about 64g, and its shell is sprayed with a matte black anodized coating.
