Dpreview posted their first impression review:
The RX100 IV fits pretty well in your hands, though those with large hands might find controls to be on the small side. The camera can be operated with one hand, though you’ll need your other hand for rotating the control ring around the lens.
Philip Bloom tested both new RX cameras and writes:
The 250fps (240 in NTSC) is excellent when in “quality mode” although just 2 second buffer and a 20 second write to card time. The 500fps (480 in NTSC) is passable on certain things, avoid hard lines if you can as it will moire and alias like crazy! 1000 fps (960 in NTSC) is ugly as hell but I still managed to get away with it in my test film. In the real world I can’t see me using past 250 fps very often. The modes where you can record twice as long are much poorer quality so I avoid them.
Ken Rockwell also tested the new RX100m4 and writes:
The RX100 Mk IV is a fantastic point-and-shoot camera that quickly and easily makes great photos in any light, and its larger-than-most point-and-shoots sensor giving sharper, cleaner images than cell phones or most other pocket cameras.

Ken Rockwell, the last word in photographic gear reviews.
Seriously. All his reviews are good for are the massive lists of tech specs. Once the product is launched. Not when he writes his “reviews” on the day the camera is announced…. -______-
Sorry I should have made a note of my sarcasm.
Didn’t need to. If there was a question mark after “Seriously”, then maybe, but I’m agreeing with you. 😉
Why are you posting anything by Ken Rockwell? He is an idiot that professionals ignore and amateurs hate. And, aside from bashing/ignoring Sony since he began his website (in what appears to *still* be 1999), he has this to say in the “review” you just linked to regarding the RX100 IV’s lens:
“It’s certainly sharper than most of Sony’s DSLR lenses, which are pretty bad!”
Why are you linking to this moron? I’m not a fan of Kai, for example, but *some* people actually like him– and he seems to be getting better. Rockwell, on the other hand, posses technical sense that is both rubbish and biased, and opinions that are even more rubbish and biased than the bit of knowledge he’s acquired.
Oh, and take a look at the picture of what he calls his “Rolex Submariner,” which, since it’s obviously a fake, I’m assuming it’s some kind of sad, snarky joke aimed at people who spend (“too much”) money on high quality watches.
“Test” criteria: Will it make oversaturated carnival colors in OOC JPEGs when I set saturation to +10? Hilarious.
There are no professionals here. All Sony rumors have are techies with a camera. Rockwell is a perfect reviewer for Sony fans to look up to.
Nice one Phil.
Ken Rockwell is there if only to stoke the egos of Nikon and Canon users. All other cameras are crap to him.
It always blows my mind how ugly Ken Rockwells photos are. Sometimes I wonder if the man is a genius or an idiot. Genius because morons who fail at photography eat this s**t up and buy through his affiliate links. And guess what, there’s 100x more morons on the internet than capable people. Brilliant from a business perspective.
I really enjoyed PB’s “call the cleaner”. Good idea to demonstrate the high speed modes.
Could be a benchmark set for others! How much light does it need?
I enjoyed it too and I think he enjoyed to play with food if he s not the one who may clean afterwards;)
The recommendation of Ken Rockwell to “not buy from any dealer that is not on my personally approved list” (of affiliate links) looks like a new dimension of beggary to me.
Ken Rockwell does something the MFG fails to do, which is present good close up images of their products in sharp clear detail, presents the tech specs in an easy to read format. for this I praise him. What I dont get is why Saturate each image +3, what does that prove, i can see how ppl complain about terrible images. My take is, he is just taking pictures somewhat random they are not really to be taken serious. He does give camera praise for what it is. I think this camera would make a good compliment as merely something easy to use. something which can be kept in a purse. Ken does seem to be douche in his comments and some ppl swear by his reviews, and i get it! I merely use his site for tech specs, nothing more. Personally i think the rx4 is too expensive, for that much I’d rather buy another FE lens.
He might be daltonic.
Nice of Ken to be so rewarding in his comments for what is only a “point and shoot” lol
Really? Considering that he thinks Sony’s lenses are crap? The perfect reviewer for Sony fans. You make a great point.
No professionals here? You must be the real Ken Rockwell. Because, at the moment, this is *the* site to read about what’s happening/going to happen in Sony’s digital camera world.
And since Sony- for years now- is the only company that can make a great sensor (and who’s innovating in the world of full frame and APS-C cameras), you better believe “professionals” are stopping by to see what’s going on.

eoshd did a hands-on RX10II

And this video shows that zoom speed seem to be really fast now.

Sony should at least remake the RX100II with the IV internals minus the EVF in favor of hot shoe and a longer lens, then they can take the I and III out of the market. And maybe make the new mark2 cheaper.
