Thanks for your question, perhaps we will publish a detailed documentation for DxOMark score and Sharpness score… There is a lot of misunderstanding between our different scores. You can check our score documentation: http://www.dxomark.com/index.php/About/Lens-scores
Shortly, here are some key points about our scores:
- DxOMark score depends on sharpness, distortion, vignetting, TStop, sensor color depth, sensor dynamic range. This score is computed for a mid-light using condition (150 Lux and 1/60s)
- DxOMark score is not a metric computed with the optical score. They are independent even if they use the same data.
- DxOMark score takes measurement of sharpness (acutance) but not the sharpness score.
- Sharpness score is computed only with sharpness measurement and do not take into account other aspects.
Your proposition is interesting, we will see if we have time to do it (more likely we could test a prime).
