I have the CFV-50s, which is the same sensor as on both the Fuji and new Hasselblad. It works with a full system of gear I already had so there was an arguable "economy". It is absolutely stunning.
But the files are big, and when printing at any size I do (now mostly I do my own books) there is little advantage.
My conclusion today is that 24 MPX is all you need. At that point better pixels are more important than more pixels. The SL is an attractive camera, but in my case I don't see much advantage over a TYP 240 and the accessory viewfinder. I have essentially no use for auto focus or zooms.
And the SONY A7 series gives you an awfull lot of what the SL would at a massively lower price.
