... eos m. I have it since a week ...
Hello and welcome to "the M club" here. :-)
What lens/es do you use with your EOS-M? EF-M or also EF-S/EF via adapter?
Myself I got my M for about 1 month now. It's my light and compact "go everywhere camera".
ALso got the EF-M 18-55 kit zoom, EF-M 22/2.0 and EF/-M adapter, which I use fairly regularly to connect my EF-S 55-250 STM and EF 40/2.8 STM (pancake) and sometimes my EF-S 10-22 and EF-S 60/2.8 Macro.
In my experience, lenses with STM AF drive work better on the EOS-M than EF/EF-S lenses with USM AF which was optimized for DSLR phase AF.
you should try the 135L on it in servo mode its damn quick and i would say i was getting 90% keepers with the combo
other USM lenses not so much but the 135L is amazing on the M
