This is really good thinking - the sort of thing I was after.
Bear in mind I have used Leica M for years, so am very familiar and comfortable with an OVF, particularly one that lets me see outside the frame. That is part of my thinking behind my question.
A couple of points if I may.
Ray, your reference to the right dioptre lens implies no built-in dioptre correction, yes? If that is the case, what is it like to use the X-Pro in either OVF or EVF mode with spectacles? (again, bear in mind that I shoot regularly with a Leica M2 so I understand the principles, particularly the need to centre your eye).
I assume that the framelines are digitally projected; are there any that cannot be displayed?
I'm increasingly thinking that the X-T1 will be (is) my camera for 18-55, 55-200, long lens (300+) and macro use, while my "rangefinder-style" body - currently X-E1 but in future X-E2 or X-Pro1 - will mostly be used with primes and occasionally with the 18-55. For me that would mean 14, 27, 35 and 56 (I'm going to sell the 60). That makes a compact and high-quality prime set. On my "personal roadmap" in the future lie the 16-55 (to give a weatherproofed solution with the X-T1) and possibly the 23. Most of my photography could be loosely classed as "travel", mainly because that is the only "me time" I get to focus (geddit?) on my pastime.
Snapdawg. I had all the stuff I needed 25 years ago - I hear you...
