Ciao,
    Carlo

Secondo me dovresti postarlo su it.binari.file (soprattutto viste le
polemiche di questi giorni !!!)
Saluti.

--------------------------------------------------------------------------
The final results represent an averaged mark based on test verdicts from 5
photo magazines from all over the planet.
--------------------------------------------------------------------------
The results range from 1.0 to 5.0 (5 is best).
There're 6 texual marks for the optical quality:
  1. (4.26 to 5.00) = excellent
  2. (3.76 to 4.25) = very good
  3. (3.26 to 3.75) = good
  4. (2.76 to 3.25) = average
  5. (2.26 to 2.75) = sub-average
  6. (1.0 to 2.25) = poor
A typical result looks like this: 3.48 (3) = good
The number in brackets shows the number of tests included for the
calculation. Only results with (3) or more tests are more or less stable!
Everything less should be taken as a tendancy only!
