If this is the same lens I had many years ago (I think it is...),
it was decent for the price (under $100, preset diaphragm, "T"-mount).
It had noticeable color fringing, had not the highest contrast, and
was not wiry-sharp - but it was not terrible, and was a lot of lens
for the money...
Hope This Helps
