EOS M3/EOS 100D AF

[stickytape]

So I've got a query! I did a bit of nature photography yesterday with my EOS M3 and 100D plus the 100-400 IS Version 1.

I've noticed the AF on the M3 - either using the EVF or rear LCD works OK on the 100-400, but it has a "stutters" action if that makes senses? However when using it on the 100D in Live view its a continuous motion, with no stutterness? Imagine a movie and pull focus is achieved; its a nice smooth action. This is how it is on the 100D but not on the M3.

I'm pretty perplexed.. as the M3 is newer than the 100D and surely the live view focusing is the same system - albeit the 100D is a fair bit older?

any help appreciated - I'm confused!

I had a similar problem with my original 'M' using the EFS 55-250.

If I remember correctly i stopped it by switching off continuous autofocus on the camera from the main menu system.
