Things change for the better.
I don't have the A7r II but have the RX1R II (similar tech) and it is pretty good. The AF (PDAF) is so good that I do not use manual focus (for the first time) at all!
The SL will mature in years to come, no doubt about that.
I glanced through another forum and one of the mods there is claiming that the 24mp resolves more than 42mp and is getting slammed by some of the participants there.
Can anyone here support that claim (24 Leica is sharper than 42 Sony)?
I'm not going to get into it, so let's just say it depends.
