35 or 50
I find 24 is very wide for day to day shots.
Get yourself the m5 and the 22mm f2 Ef-m it is a ridiculously good bit of kit for the money tack sharp wide open and gives you that 35mm equivalent you want it finding myself reaching for my oricional eos-m and this lens do often that i'm considering cashing in my full frame gear for an m3. If canon would just put the 80d sensor in the original m body they would already have my money!
