On lens selection:
To take full advantage of the EOS M, you want:
1. A prime lens for dim light (wide aperture) that is also IS. Big sensor, fast lens - nirvana for indoors.
2. You want an IS telephoto zoom that is quiet.
3. You want a normal IS zoom that is quiet.
You want the lenses to be light and maybe small.
This is what I found to satisfy all of the above:
1. For dim light, the EF 35mm IS f2.0 USM is Canon's only
fast prime with IS. It is a new lens, and is very high quality. Not cheap. This video was shot with it: https://vimeo.com/74063702
2. For telephoto zoom: the EF S 55-250mm IS STM. It is surprisingly light, quiet and relatively cheap. A brand new lens, and it has really good IS. This video shot with it, mostly at full zoom: https://vimeo.com/75364534
3. For regular zoom: the M kit lens - EF M 18-55mm IS STM; quiet and sharp and small and relatively cheap.
Or, as an alternative normal zoom: the EF S 18-135 IS STM. It is quiet, cheap and good but surprisingly much heavier (but shorter) than the EF S 55-250mm. But then you can use this lens instead of the two lenses (55-250mm and 18-55mm) if you don't need the full reach. This video was shot with it: https://vimeo.com/73551007
If you think you do not need IS, there are more, but not necessarily better, options. Without IS, the EOS M is impossible to use handheld for video - it is too light!
Finally, if you want a really wide-angle zoom, there is the EF M 11-22 IS STM. Really small, really sharp. With this lens and the 18-135mm and the 35mm you have a big range and IS for good light and a IS for dim light (11-135mm + 35mm).Edited by markr041 - 10/8/13 at 12:12pm
