According to what I have seen, including on the B&H website, the RX100 M6 is to be released on July 10th.....so not all that far away now! As I said, I am well aware that it is likely that coming along now to place my preorder, I may well be out of the first round of shipments, which is fine, I'm not really in that big of a hurry. I have a hunch that this thing (even though it is certainly not inexpensive) is going to be in big demand for quite some time, as a lot of people who are already familiar with the RX100 series probably have been wishing, just as I had been, that the zoom range was just a bit longer.....and now it is! Great for a travel camera, among other uses. It's also kind of nice realizing that now I won't be obsessively checking my local store's website every day; I can just relax and wait for B&H to notify me that my camera is on the way....whether it's next week or three weeks or more from now....
In my mind, this fixed-lens compact camera in no way replaces a larger camera with interchangeable lenses and larger sensor, and that is why I am also still thinking about the A7III..... I have a 12" MacBook that I love but which I would never consider using as my only computer, it is in addition to my other, larger and more powerful machines; I feel the same way about the RX100. It has never been and would never be my only camera. I've had an RX100 since 2014 and have found time and again that it's a great little camera to tuck into my purse for various situations, including travel, and (ahem) at times when attending concerts..... It goes into situations where my larger cameras and their lenses, even the NEX-7, would be immediately frowned upon and regarded as intrusive. The RX100? Small, sleek, innocuous-looking, to the casual observer, oh, just another P&S.....when in reality it offers the user a larger sensor than a run-of-the-mill P&S plus so much more control than that.
You make a good point about various stores' return policies, and that is one reason that I would not order an A7III from B&H without ever having even seen or handled one, as I am familiar with their particular policy, which is more restrictive than many other retail establishments. That said, I have had good luck with them in the past, including with a laptop one time some years ago, so the need to deal with the return policy has never occurred, thank goodness. Actually, I am fortunate in that I live in an area where there are still a (very) few camera shops around where I can indeed have a hands-on experience with just about any camera and lenses in which I'm interested, and for me, that's worth a lot. I know that one of these days I'll suddenly get that itch again, GAS, which has only been temporarily quelled, will strike full-force once more and I'll find myself in the car heading to the camera shop to have a look at the A7III.....
Since they probably have a lot of preorders my camera may not be one sent out in the first shipment, but we'll see.... Since I have no idea how long it might take for the local shop to get them in stock, and I am eager for this, went the preorder route this time.
