I wrote about how good the crop mode is in my A7II review. With lenses designed for denser sensors, the 10 MP crop is really high quality.
For me, crop mode on my A7r is useless for stills (I can always crop better in post anyway), but for video, I actually do get more reach since the target resolution (1920x1080) is much less than the actual resolution, even in crop mode.
Crop mode on a7II would give me a chance to make my photo system more compact and universal. I get a camera with only one lens (FE 55/1.8) and the same time excellent short-tele FF equivalent about 85mm. With one more lens - 77mm - I get medium-tele FF equivalent 120mm (115mm to be exact) which I got used to during long time exploitation of 77mm on APS-C Pentax camera (and which I adore). 10Mp is enough for me, especially for portraits or close-upped fragments for what I actually need these two virtual lens - 85 or 120mm. For long shot pictures you will have 24Mp to look closely at the details or pixel pip. Those guys who prefer street photo style diapason about 28-35-50mm will get it with only one lens like Sonnar 35/2.8 or Sony 28/2.
I used it one time, and the resolution drop in the EVF and LCD was crazy. It's kind of hard to describe, but basically it's just artificially enlarging the APS-C size of the sensor readout and blowing it up to fill up the full screen, so it's a lot more pixelated. I wouldn't use it for anything serious really, at that point might as well get a good APS-C body. I can't personally see the utility in buying a bigger full frame camera and using a tiny portion of the sensor. I'd rather use my Nex 5 just because of size and the LCD resolution being technically better.
