It can be used on lenses with series 4 (25mm) threads. Even though it says 21.5mm on the box. But I have measured thread size as 25mm. It is a screw in type.
Hood has been used but works great. In good condition. It has some
scratches and some paint damage, but threads are not damaged. it is not
bent.
Appearance rated at 9 out of 10.
It will be shipped just as pictured. No other accessories will be included.
