Sony 75-300mm vs Sony 18-70mm resolution comparison

  To measure and compare the Sony 75-300mm'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 75-300mm with the Sony A100 body at a focal length of 75mm and compared it to the DT 18-70mm at a focal length of 70mm. The sharpest results on both lenses were found at an aperture of f8, where the 75-300mm lens delivered 2000 and 2050 lpph of horizontal and vertical resolution respectively.

This result is measurably lower than the 18-70mm kit lens, at their closest focal lengths anyway, so if you're shooting at around the 70mm point, you'll get better results using the kit lens zoomed-into 70mm than the 75-300mm zoomed-out to 75mm. To be fair, the Sony 18-70mm kit lens is better than most though, and the A100's resolving power with the 75-300mm aren't far off the Canon EOS 400D / XTi with its 18-55mm kit lens.
