Amateur Photographer magazine, written for amateurs by amateurs, really?
Well it seems to be a fairly successful formula:
"Amateur Photographer was first published on 10 October 1884, making it over 130 years old. It has established itself as the world's number one weekly photography magazine. Some of the most renowned photographers such as Alfred Stieglitz, Frank Meadow Sutcliffe, David Bailey and Bob Carlos Clarke have written for the magazine over the years".
The results were based on something called the DxOMark optical test database, and the caveat that "the DxOMark isn't 100% comprehensive, and not not all lenses have been tested on all cameras" was included, if you want to analyse the raw data they used you can take a look at
DxOMark by DxO - DxOMark.
