The enigma of the ZI.

Actually, I think the full frame sensor issue is the least concern for an digital RF because it would require buying one or two new fixed focal length lenses (at the wide end, of course). This would be cheaper than buying a quality super wide zoom which is what many DSLR users need to do to match their APS-size sensors. Also, bear in mind that it costs quite a bit less to buy a new wide angle lens than it does to upgrade to a full frame sensor.

In some ways you are entirely right. Full frame sensors are only an issue for RF cameras because M mount lenses at the extreme wide-angle end for APS sensors just do not exist. The widest is the CV 12mm, which is about 19mm EFL on APS format. To get down to 12mm EFL, you would need a 7.5mm lens. This is perfectly possible for APS format, but you can't buy one yet. The other point is that sensor costs are still falling fast, and likely to continue doing so for some time. You can;t say that about lenses 🙁
