Please note that hood is single threaded, it lacks threads in the front.  

It will fit 50mm f1.4 and 55mm f1.8 f2 lenses. 

Lens hood has been used. It shows normal wear. But it looks and works good.   It will be shipped as pictured.

 This lens hood is fully operational and functions as intended.  I would rate it an 9, on a scale from 1 to 10.
