Blathering on some more...
Sometime -- when -- IF? -- I get around to it, I can see dozens of menu items that may or may not come in handy. For now, the very basic and "photographic" parts of it just really work, and really work well.
The pictures, examined on the larger screen, simply impress and from long experience are what I bet are going to produce very beautiful prints, or any other end display.
I see it's traditional to include at least one whine, so here's a possible one. I'm a Photoshop user on a version a bit behind CC. Camera Raw can't "see" the RAW file version Panasonic has graced the GX7 with. This may actually be a blessing, since DNG Converter makes a good job and file sizes trimmed by 3-5MB each, of the native RAW files. So one extra step, for this workflow. YMMV. As they say.
The EVF feels and looks like a good SLR vewfinder and -- I know the nigglers who obsess on these things can tell me off -- the perception is of no delay in any of the process of taking a picture or looking at what you've done. At the moment of shutter release the EVF "blinks" dark, and so briefly it's only just preceptible. If I'm following a person walking across the street, the viewfinder image reappears so fast (really it's about like the dark interval using an SLR while the mirror is up, but, I'd wager, much shorter than that), and the lag is so minimal, that it is clear from what I see in the finder that the exposure happened when I hoped it would, and not...later. This last is confirmed if I shift my attention to my sly other eye squinting around the end of the camera.It's one very deep instrument.
Well, this will be 2 cents or a mere drop in a very large bucket. I am a GF1 fan and user, but the GX7 newly arrived is just so far beyond any (ANY) digital model I have ever used that I am simply overjoyed.
It sits in one's hand like a Leica -- or maybe like the OM-1 of yore. Controls are where they "should " be; almost from the first outing things seem to fall under my fingers without thinking about it.
The whole flow of taking pictures, being at the ready, and of the camera's overall quickness, make it a joy to use.
Then there is silent mode. There. I took a picture. Did you hear it? In fact, several.
