Smartphone post?
However, true - and one of the reasons why I opted for the X-E3. The X-Pro2 I held at Photokina felt bigger than my M10 (though much, much lighter). I thought it was a bit counter-intuitive to put a smaller sensor in a bigger, hollow-feeling body. It handles nicely enough, though, much better than any Sony APS-C camera to date, including the A6600. I find that camera somewhat strange, too, because it sports a bigger grip than my A7 II while being considerably smaller and lighter still ... But it feels really comfortable in the hand - not as good as the Z 50, but pretty close, and much better than any A6*** camera before it. That said, I don't mind the A6000's handling - it's quite okay, the camera is extremely small, pretty light, yet feels quite well made.
The A7C looks like a well spec'd mid-range camera in a remarkably small body; FWIW, it may be somewhat thicker than the A6600, more like an A7 II in that respect, but that doesn't mean it'll feel uncomfortable in the hand. It's 15% lighter than the A7 II, and the A6000-type grip is actually surprisingly well shaped to hold and handle. And the small size and reduced weight, still including the beefy battery, is very intriguing and appealing.
What I find increasingly counter-intuitive is the choice of EVF. I mean, even the A6400 has a better solution, similar panel with 0.7x magnification and 23mm eyepoint (the same values as the A6000 - but that camera has a lower resolution). A7C: 0.59x with, wait for it, 20mm eyepoint! For me as a glasses wearer, this sounds like bad news: The worst EVF in a camera I still own is in the GX9, 0.7x magnification, but really insufficient 17.5mm eyepoint; it's bearable, but far from satisfactory - in fact, not a camera I'd recommend if your main reason to choose it *is* the EVF. Still, it's just about usable. More interestingly, the Canon G1X III's finder seems really small, but still has 0.62x magnification (5% more) and a 22mm eyepoint, and it's high-quality, though a bit dim (which I discovered when using the much, much better Z 50) - so, the A7C is probably still usable, but too small to be enjoyable for quite a lot of people, including me. Pity. Especially since one or two millimeters (0.1") of additional heigth wouldn't have made that much of a difference to the body's dimensions, but a big enough difference to the quality of the EVF.
I'm not interested in a camera at that price point that doesn't offer a really good EVF. I think this is a really marginal choice by Sony - design over functionality. Always irritating.
