I have for some time the 50mm f / 1.8 D. I was in search of a bright objective with beautiful bokeh. This was done with the 50mm f / 1.8 D. With an aperture of f / 1.8 af / 2 blur are superb and the picture pic is exceptional for my camera which is confirmed by DxOMark test. My boxes will be succeeded but my 50mm f / 1.8 D will always match.
