Peter - might be better if you make a new thread for your question.

Is it the older version or the 'new' one? (which has just been discontinued). There are a couple of threads running on various Elmar lenses, but either is fine for your M6. The newer one will be sharper and more contrasty. I have one of the older versions and it is also a very fine lens, ever so slightly soft at 2.8 but stopped down to 5.6/8 its very sharp.
