As I mentioned in the other thread, their discussion was good, obviously biased toward a DSLR style camera, but I think they left out a few points:
* IMO the form factor of a camcorder cannot be beat. I've used both the DSLR form and the camcorder form for shooting video. For stability, there's no question in my mind the camcorder form factor is inherently better for video and more stable.
* The RX10 is great, no doubt about it, I love it. However they omit the biggest issue (IMO) with the camera, and that's its relatively poor OIS. It's almost impossible to get anything approaching a steady clip when you're anywhere near the limit of the zoom. Thus I try very hard to stay away from that and that effectively limits the zoom range. That should not be a factor at all with the AX100 as I expect the OIS will be more effective and the form factor will make it easier to hold steady. Sure you can carry a tripod with you, but that kind of defeats the whole concept of portability.
* The DSLR type camera for video (not the RX10 obviously) is prone to sensor dust when changing lenses, which can be a real problem once you get it. Particularly because you'll often not notice it until you get home. Even if you do see it while shooting, there's not much you can do about it in the field. Depending on the location of that ugly spot, it can really ruin your videos. No such issues with camcorders. I've had it happen on my NEX VG20, VG30 and Panasonic GH3. This is despite me trying to be very careful and very quick while changing lenses.
* You will generally get a very nice range of focal lengths with the one fixed lens of a camcorder. To duplicate that in a DSLR will generally require several heavy lenses.
Now these are obviously pluses for a camcorder and you can come up with another list in favor of a DSLR. But the reason I went with the RX10, was to get the great videos & stills, but not have to worry about lugging around a set of lenses. I really have no desire to do that anymore. Even if I got a GH4, I'd almost certainly stick the 14-140 lens on it and be done.
As for stills, I remember getting some very nice stills with my VG30.
For me, I'm full steam ahead for the AX100.
