Sony DT 16-80mm vs Sony DT 18-70mm resolution comparison, with Alpha A100
|
 |
|
To measure and compare the Sony DT 16-80mm's resolving power we photographed the Enhanced Digital Camera
Resolution Chart with it and the DT 18-70mm kit lens using the Sony A100 body set to its
best quality JPEG and default image tone and sharpening settings.
The crops are taken from the original images, saved as High Quality JPEGs
in Photoshop CS2 and presented here at 100%. Each number represents 100
lines per picture height (lpph), so a figure of 20 means a resolution of
2000 lpph. |
We tested the Sony DT 16-80mm and DT 18-70mm lenses with the Sony A100 body at a focal length of 35mm and at each aperture setting. The sharpest results on both lenses were found at an aperture of f8, where the DT 16-80mm delivered 2200 lpph of horizontal and vertical resolution respectively.
This result places the DT 16-80mm fractionally ahead of the kit lens, although both perform well in terms of sheer resolving power in the middle of the frame. The differences between the lenses become clear in our other tests though, particularly the real-life outdoor results, so be sure to check out each our these pages to see the full story. Next up, the Sony DT 16-80mm corner sharpness. |
