Summary: Got this set with a new XH-A1. They work as advertised. maybe I could have saved a few bucks with another brand but I assumed the optics here were as good as the XH-A1 lens so why take a chance. My only complaint - the filter set came with a leather carry case which somehow I did not notice in the advertisement. The reason I am complaining is I didn'tknow there would be a case so I bought a set of 72mm metal scrw-on end caps. Basically I wasted a few dollars on the caps.
