| Sony 75-300mm vs Sony 18-70mm purple fringing comparison |
 |
|
To compare the purple fringing of the Sony 75-300mm against the Sony 18-70mm, we photographed a test chart with areas of very high contrast using each lens at their shortest and longest focal lengths and
with their apertures wide open. The crops are taken
from the upper left corner of the chart and presented here at 100%.
Both lenses exhibit purple fringing at their shortest focal lengths, although the 75-300mm shows a very clean result when zoomed-into 300mm. |

Sony 75-300mm vs Sony 18-70mm macro comparison
| To compare the macro capabilities of the Sony 75-300mm against the Sony 18-70mm, we photographed
a custom chart at a focal length and distance which
delivered the maximum possible reproduction.
The dark lines are 10mm apart and the result is not cropped. Smaller areas
are preferred in this test. |

| The best result we could get from the Sony 75-300mm was set at 250mm where it delivered an area measuring 98x66mm. The 18-70mm kit lens can deliver a smaller area though and at much closer range too, so is unsurprisingly a more practical option when it comes to macro work. |
