It seams that everybody is preoccupied with tech specs and bunch of hardly relevant data.
Ergonically, I like it - albeit it's a cheap compromise - but I think you would have to try it with the lenses you are going to use.
It hangs down, front heavy. It is not so fast but it is unobtrusive. Pre-focussing would have to help - the focus needs the magnification view which is another button. It releases the view when you touch the shutter button, ready for the shot.
LCD rotates up quite a way and down less so, but enough to be quite useful. Haven't used it in very bright conditions yet but a Hoodman may help here.
Once the menu options are set up (which are pretty clumsy) I don't touch much else. The camera balances on a couple of curled fingers of the left hand, supporting part of the lens as well and works nicely like that. Portrait is a bit clumsier but not impossible.
I shoot Auto ISO in A, no tweaks needed as yet.
Very light and thin. The Leica CL is not exactly ergonomic perfection and the NEX is not bad enough for me to leave on a shelf, by any means.
