The OP asked a question about how to perform some MTF tests to a FED lens he has and how the admittedly imperfect method he would use would affect the results.

He received answers stating that MTF tests are useless and a user inferred the OP thinks the FED lens was superior to his Leica (which the OP never stated).

A discussion about MTF or resolution tests and their relative scarce utility in measuring the quality of a lens would be a welcome discussion but in this thread is OT just like a comparison between Leica and FED lens could be interesting but OT.

Dan is right that, for the most, this forum ignored the OP question and just begun questioning his motives to ask it, which just lowers the noise/signal ratio. This post does not raise it either but can be taken as a remainder to be more disciplined in forum behaviour
