With the 20mm 1.7 it seems a little killer. Reminds me of my dad's Trip 35 on a concept side.
Foveon in m4/3. Now that would be nice! I like the more film rendering it has. However, people complain about its ISO performance. ISO 1600 is all I ever need every once in a while.
m4/3 is that middle land... True that it seems to be pushed above and below.
For DoF control (as some say; IMO, funny term) m4/3 has more DoF with smaller lenses which is better for wide and deep shooting (street scenes, interior, etc).
One thing that frustrates me a bit (on the print side) is that despite 4:3 is used by many compacts... It requires a bit of work around... Then frames and storage accessories still are stuck at 4:5 proportions. 2:3 has relatively OK options.
Obviously there is no comparison, market wise, to the Sony A7r. However, the sony has snatched the attention of everyone everywhere!
I am amused that it took too long to miniaturise Full frame again. 35mm could get quite small (those little compacts) with small lenses (not f2's however) but it was done.
Well, let's wait for a digital Rollei 35
Now that would kill.
I'm one of those that like the market for "big" compacts. Can do fine with a small prime.
