If I remember correctly the measurements here at photozone are indeed based on JPGs. Lenstip uses (processed?) RAW-files.

 

Of course PZ doesnt feed Raw-files into the Imatest module ... anyhow,

I doubt that OOC Jpgs are used ...

 

A cite from the Lenstest FAQ:

"There're also evolutions regarding the RAW converter quality so more recent system tests starts can benefit from this - e.g. Canon/Olympus RAWs are/were converted using ACR 3.2 whereas Pentax/Sony RAWs are/were converted via ACR 3.7 and there was an increase in converter quality with ACR 3.4). This must all be taken into account regarding the rating system."

 

In this context, I doubt that the said-to-be 40Mpix files would have been used ... there is no Rawfile ...

there is only the Jpg OOC.
