I was looking today for a new lens to replace my old 3-element lens and I came across this cheap 2 element lens on ebay.
I was unable to find any information on it, so I was wondering if anybody knows anything about it or if it is any better (in terms of efficiency) than the 445nm AR 3-element lens due to it being a 2 element lens?
