The APS-C of my X-E2 suits me fine.  I can keep a 50mm on it all the time
yet get my favorite 85mm angle of view with a 50mm lens' smaller size. I
hardly ever want to get a wider view than a 50 gives on FF, and I get that
with the 35mm Summicron.  I take my few wide shots with the LX3.

I once analyzed the stock slides I shot on my 1984 trip to Britain.  The
general breakdown by lenses was: 50mm (44%), 100mm (22%), 35mm (15%), 21mm
(11%), and 300 mm (8%).  The breakdown by my favorite pictures was 50mm
(57%), 100mm (27%), 21mm and 300mm (6% each) and 35mm (3%).
I didn't have an 85 for my OM's, or that might have been the favored lens.
