I don't see the replies as 100% OT.
There are two more valuable replies by Klaus.

Yes, you're right: I've specified in the "(not taking into account Klaus reply on the sanity check)" that Klaus replies were near to what I was looking for; two usefull contributes, in other words. Sorry if I wasn't clear enough...

2nd: if you still insist to use a similar testing approach as we do...

Great! Thank you for all the information you provided!
I know the procedure is really challenging, mailnly due to chart-camera alignement problems, but I still need to assess the sharpening focus issues of my lens from an objective standpoint. Subjective opinions lead to a "dispersion" of results that has no usefulness in judging acceptable limits for a lens behaviour.
I use Quick MTF tool mainly because of the price of the light version, more compatible with my target of private user. Furthermore, I think that Imatest and Quick MTF rely on the same public domain SFR routines...
The reason for my interest in your testing procedures was mainly due to the preliminary results I've obtained from my tests; the big difference with yours were asking me if I was missing the right approach.
So, thanks for you support and what's more for the great reviews you share with us!
