Concerns over the Leica Q2

Here are the things I’m concerned about before I can say I will invest in the Leica Q2:

1. Back Button Focus – read my concern over this in my post “Have Leica broken Back Button Focussing on the Q2?” – I’m hoping this will be rectified in a firmware release.
2. Position of the EC Dial – compared to the Q, the thumb dial (which I would use for EC) has moved slightly round the back corner of the right hand side, making it slightly forward and right. My concern is whether it is still easily accessible in that position.
3. ISO Performance – in general smaller pixel pitch tends to mean worse ISO performance, but the Q2 sensor is
4. Crop-Zooming – I’m now OK with this, as per my post “Why I’m OK with crop-zooming on the Leica Q2“.
