Najważniejsze, moim zdaniem:
Having taken many hundreds of frames with this lens during my week in Iceland I can tell you that this is one first-rate optic. No formal tests are needed to let me know that this lens is sharp, contrasty, and quite free of any serious aberrations – at least those visible without conducting a formal test suite.
