The baseplate of the M9 could be the problem, because I am using a tripod.

 

This picture is as good as it could get at infinity. 2. picture is a detail from lower left corner.

I'm a bit baffled by this, how does a camera baseplate affect focus? It may affect stability, but even the M9 baseplate is good enough to hold a 135mm lens without wobbling about. If on the other hand mean your images when looking at the results at infinity aren't entirely sharp, then you can usually blame atmospheric haze and distortion.

If a short say 2" QR plate is used on the M9 (or any M for that matter) one might get some side to side wobble.  I only have used around 6" long QR base plates for this reason if not using an L bracket.

 The baseplate is "wobbling about". I need more test shots, because I can not get consistent results.
