my love-hate relationship with the RX1

Good point.
I did not know that Sony finally added Auto ISO in M mode. My RX100 does not have this.
I was responding to barjohn who said he would never buy an RX1 because it would not allow him to set a minimum shutter speed when using Auto ISO in A mode.

Your reply is much better than my work-around that I use on my RX100 to address this issue.

Thanks,
Bert
