But the new EF-M 15-45mm can be used with the original EOS M, with ML. I suppose dfort was refering to this.
Yes, another EF-M lens and if you collapse then extend the this one you can kill the shutter-bug like you can with the 11-22mm. Sort of a strange choice of focal length though--something between the 18-55mm and the 11-22mm.
If cam's firmware is close to M3 there will be not that good a chance killing anything with ML. See M3 thread -> Powershot derivate.
The M10 was announced with a couple of other PowerShots, the G5 X and the G9 X. Wonder if they named it the M10 because they were going to call it the M X. All kidding aside, looks like it might be another one for the CHDK project.
