Apparently there's a smaller sized "consumer" version coming out soon as well, just like the Canon one.I currently shoot Sony (A7ii), but had a play with the Z6 today while putting in my preorder for the Ricoh GRiii. Wel, I must say, I was very impressed. Excellent build quality, great feel, and the AF seemed very snappy. EVF was really nice too. Tried it with both the 24-70 and 50mm S lenses. Very impressed with them as well.
I think you made a good choice selling of the F gear for replacements in the S line.
