Dominique, speaking just for myself who uses and enjoys the Cosina 15 and
25, the lens quality is very good, the price for value ratio is
extraordinary and it is a pity Leica can't do as well. Now my 24 Elmarit
Asph is better than the skopar 25 - no doubt, but at the middle apertures
and out street shooting you'll not see a difference, except that the skopar
is much smaller, less noticable and that is appealing in itself. We have
discussed MPF curves on the LUG many times, but the real proof,in my view,
is in shooting pictures.  As others suggested - you should try the lenses.
