Lenses are mass produced and you have to be very fortunate if you get a perfect example. I have helped many with correction issues. However, I take your point about not knowing the focus points, but I am merely stating this as a possible solution taking into account that the photographer knows what he is doing regarding his subject and what he wants to portray but still not getting the sharpness. | |

Why do you think there is a problem with the lens's focusing mechanism rather than the photographer's selection of which point to focus on? How do you come to that conclusion without even knowing what the photographer's intentions were, in terms of what parts of the photograph should be sharp? | |

| Apr 13, 2015 at 1:37 | comment | added | Brandon | what is a more appropriate lens to use to use for this type of shots? Is it a Macro lens area? | |
| Apr 13, 2015 at 1:08 | comment | added | Michael C | Yes it has more bokeh, but the color is nasty and the composition is a jumbled mess. It was also uploaded at roughly 3x the linear resolution of the one from the zoom lens which makes it impossible to say which image is truly sharpest. You are correct that normally prime lenses outperform zoom lenses in terms of absolute acutance. But without having images of comparable resolution it is not possible to say which of these two photos is sharper. And absolute sharpness is worthless if the wrong part of the frame is the most in focus. | |

The 24-70mm is a great pro lens, but perhaps not so much for this type of photography | |
