You can’t win here.
It doesn’t matter how independent you make your test, how many independent people are present someone will always say that you’ve rigged it or cheated.
The test I published in 2002 comparing Fuji, Kodak F900 and Viper were criticised by Kodak because their images were soft, yeah and they were the ones who scanned them soft!
It didn’t matter anyway as the tests were about Dynamic Range not resolution.
As I test more and more and more I know what to expect and I’m rarely surprised anymore.
My latest tests, these are half of a 800/3200 comparison of these cameras and are in that page to show differences between the colour of the cameras.
