Therefore I decided to my RAW processing in Capture One which I am familiar with. Unfortunately I had no references of how the reviewers did their processing. They only state that they use the Imatest software....

Hi Frans, I'm trying to evaluate sharpness of a recently bought Fujinon 150-600 on my X-S10 body. Fujifilm show very good performance at 45 lp/mm on the wide and tele end. Optical limits found an mtf50 of >3000 lw/ph near center 150-600mm wide open. Digital Camera World found >1500 lp/ph (? no axis label, smh) 150-400mm. So the reviews seem to agree. And from what I calculated, this would correspond to 0.33 c/p on my 4160 pixels high sensor, correct? I played around with mtf mapper and an A4 printed...
