Well, I've been reflecting and I've cancelled my pre-order !
The problem really is that I like the current S1/S1R a lot.
So they didn't go off to MPB after all?
But I can understand this: I'm still unsure about the S1Rii myself. I'd definitely appreciate having a high resolution camera with IBIS, a viewfinder, improved AF, etc, but I really like the small size of my fp L and the quality of the photos it produces: I've never been able to get my S5 photos to look quite as nice in terms of colour. And since I'm definitely keeping the fp L, would an S1Rii just get left at home unless I knew I was going to photograph something that demanded its abilities?
I guess the answer is to wait and see if the S1Rii appears on https://www.lumixloan.com so I can try it out for myself.
