Here at a camera store in Berlin we have the 3 musketeers.
2012 vintage RX1R OG, the one without the AA filter.
It's very nice and I can't understand why it only goes for $900 used. Because it's got a much better lens than the Leica Q.
No red dot though.
RX1R II, the one with the tilt screen, phase-detect AF and pop-up EVF. It also shoots 120p, albeit no 4K. It also has a further innovation - the AA filter can be switched on and off.
This was Sony when they felt they needed to catch up with Canon and Nikon by really pushing the boat out. 2014-2015 vintage Sony. The $2000 mint condition used RX1R II is reasonably rare but when you do find one, it's still cheaper than the Leica Q OG and closer to the Leica Q2 in terms of image quality.
The pop-up EVF is mechanically a thing of beauty and offers a big field of view. Although without a rubberised eye cup, it isn't the most ergonomic or comfortable.
So to the new one, the one with the 10 year gap.
Sony have made sure to price it so that nobody buys one, which is good because they want you all to buy E mount lenses.
Just to summarise the street prices:
RX1R: $800-900 used
RX1R II: $2k used
RX1R III: $5100 / 4900 euro
The lens is identical to the previous cameras.
Which is fine to be honest, but I had more issues with the AF in macro mode on the RX1R III vs II. Weird.
I also dislike the finish and build quality, doesn't feel as premium. It feels a bit like the A7CR. Not great and nowhere near a Leica and the RX1R II also feels more premium. I do prefer the buttons though on the new camera, they are raised for a more tactile feel.
Gone is the pop-up EVF, in place of it a smaller standard one. The resolution of the live-view feed is better, but the overall optic is worse and more pokey.
Gone is the articulated screen. Which is a really weird one.
In comes a fatter battery - very welcome.
4K is there with no crop in 24p/25p... However, there's no IBIS or even OIS, which is a downer.
The AEL button has changed to an AF-ON... Again a welcome change, because the first two models had no back-button AF at all. Well done Sony.
So if you're looking for a full frame compact, the first two models are a steal.
I got the RX1R II again.
I regretted selling it the first time out!
