Thanks!
Got it. Very powerfull feature indeed. Combined with C1-C2-C3 it's so easy to get direct access.
I'm not sure anybody will see the difference at lower isos in the 1:1 mode, it's there but frankly for the pixels maniacs and, as MR pointed, at lower isos.
Tried with a 37mm and yeah, focussing hand held as expected is much more critical but still usable, with the Zeiss 135 forget it.
The very positive thing of this, is located in e-bay; shhht because the market is already speculative enough when it comes to m4/3 mount but everybody with common sense can draw his own conclusions and know what to look for discretly.
But to add more confusion, if you engaged the ETC in the menu, you'll notice that there is just below the digital zoom mode function. It's possible to combine both but then with manual lenses it's virtually impossible to get focus when you mixed with DZ. That's frankly confusing and I ketpt disabled the DZ but a doubt still there.
