That's funny, because their countrymen from pictchallenge rated DA 16-45/4
very high and said its performance is similar to hi-end Nikon DX 17-55/2,8
except for slightly higher CAs at wide end.
Definitely puzzling... Chasseur d'Images also uses DXO analyser for all
their tests, including this one.
Either they got a faulty unit, or they messed up their testing protocol.
