I would much prefer to see a setting of ISO 25 on a M10 if or when such a camera comes to the market.
You could just use an ND filter. I am not technically well versed in sensor matters, but I imagine the base ISO is where you get the best signal/noise ratio. So thinking if sensor optimised for Iso 25 higher Iso would suffer an increase in noise or else the lower Iso levels would be inferior to base Iso performance. I agree though that it would be handy to have that option rather than having to screw on an ND filter.
