That's maybe why Leica used BAS test for the marketing strategy . I received my copies of the BAS tests for free via various Leica dealers here in Belgium. Each prominent dealer received a lot of them to be distributed. BAS don't look so independent after all. Now, I agree with what they say about the Leica lenses in those tests. ;-) BTW, are you an expert in lens test ?
