I still have the one I purchased new when I bought my F2 in the early 70s. I was in college and working at Disneyland for rent and food money. I wanted a lens that would allow photographs in very low light, since I was working night shifts and wanted to wander around after I was off. This lens did the trick nicely. And still does, as I still use the same camera/lens combination today.
I think that if the choice is between a slightly less than optimum quality photo, or no photo at all, there is no argument to be made. And unfortunately a NOCT was light-years out of the question.
