I'd like this feature, and would also find an in-camera down-sampled 24mp and 12mp raw mode useful as well.
Like a Corvette that can run off 4 cylinders at highway speeds to conserve energy, these high megapixel cameras need an easy button and still give you that dynamic range in RAW.
If one simply wants to get great gas mileage at highway speeds, why buy a corvette though ?
If 24meg RAW files meet your needs (and frankly, I think they do most peoples, because lets face it, just a year or two ago we were falling all over ourselves for 24meg) then why not spend a whole lot less and get the original RX1 ?
Same with threads I see on the A7rII and how people want less resolution options because they say they have no need for more megapixels....? Well why not get a A7s II and have 12 megs of bigger pixels in that case ?
Perhaps camera progress has finally outpaced our actual needs ?
We want/need 12 or maybe 24meg max, but feel we should have 42 "just in case" ?

If you want a flash that acts like it's bigger brothers than a Nissin I40 is really nice . Bigger yes more useful no question. Just for comparison it really is nice on a A6000 for instance. Just a bigger option here.

More DOF . Can't get it without more flash power . If that's what your after. Grip and grin crap I'm at least at 5.6 or more. Obviously depends on needs as a leaf shutter is most useful outside for fill . Inside work maybe has no advantage at all

Yes, the flash sync advantage comes with higher shutter speeds when shooting outdoors.
At f/2, the RX1R/II syncs at 1/2000th.
At f/4 the max sync speed drops to 1/1600th and at f/5.6 it drops again to 1/1250th.
So for example. Let's say you need 1/250th, f/8 @ISO 100 to proper expose your background. That would be the Sony A7RII max sync speed and you wouldn't get a shallow DOF.
With the RX1R/II shutter leaf, you could get the same exposure, shallower DOF with flash sync at higher shutter speeds:

I'm confused, usually with leaf shutters the shutter speed is slowest when wide open as the shutter has to travel further across the iris, and max shutter speed is attained when stopped down.

Matt I think it the shutter starts wide open and closes why you can get faster shutter speeds because the travel time over let's say F2 aperture is much quicker than stopped down at 5.6. Takes longer to get past the 5.6 aperture size. So it starts wide open than closes than exposure or shot is over and open backs up.
My question becomes Fred are those standard settings only and I'm assuming 1/2000 is the top end shutter speed usable . Hassy lenses for instance the top is 1/800, phase one LS lenses it's 1/1000 and I think Leica lenses on the S body it's 1/500th. These are all leaf shutter lenses in MF which is a different beast of course but same principal. FYI large format lenses 4x5 cameras are all leaf shutters and most top out around 1/500th. Heck I'll go further for the newbies a leaf shutter acts like a aperture ring from open to close in a circle. Focal plane shutter are vertical traveling , why on most cameras if you try and shoot faster than 1/250 you will see a black band on the bottom. The shutter is traveling to fast and cuts off the exposure. All 35 DSLRs are focal shutter rated at either 1/125 the or 1/250th. When shooting with the 1/250 on a DSLR outside with sun you need more flash power to one blend in or overcome the sun output so your typical looking for a flash that can output to maybe F11 because your ambient light at ISO 100 with our sunny 16 rule is at 1/250 at F11 from memory , so you need flash output that can get that much power out. Leaf shutter with a faster shutter speed you can use less flash power to get the ambient light under control because your using a much faster shutter speed let's say 1/2000th at F2. So you can control your DOF easier to wider but if you want to shoot stopped down remember you need plenty of flash power to do that. Lesson of the day, sorry going on 3rd espresso

One reason you may see wedding shooters doing group shots outside with bigger 600 watt flash packs because they need F5.6 or F8 to get the DOF and two to throw plenty of light out to match the sun output

Let me get back to why the RX2 (what I call it ) having that leaf shutter is a great tool to have . So say the sun is 1/2000th at F2 if you have a flash that has good output you can get the flash output to say 5.6 than shot st 5.6 at 1/2000th and your making the sun background 2 stops darker. You see a lot of fashion shots like this get the model properly exposed at 5.6 but the background gets nice and dark because your basically now taking over the sun. So lots of tricks can be applied with flash and the RX2 for different effects and also to control DOF and fill flash. Great tool to have if you shooting people outside and you don't need those big strobe packs all the time.

For some of us that shoot 35mm format getting a leaf shutter in the RX2 is a big deal. For me it tips the scale to get one at some point. Otherwise your looking at getting into MF at huge costs. This becomes a real bargain if this is what you typically shot , wedding, fashion, people. Sure it's a fixed 35 lens but you get plenty of MPX to work around some of that.

The entrance pupil when the aperture is set to f/2 is physically much larger than when stopped down to f/5.6, so it makes no sense that the shutter is able to cover a large distance more quickly than a small distance.

I'm not sure what you mean by this, sorry!
I found the following in the imaging resource review for the RX1:
The Sony RX1 offers shutter speeds ranging from 1/4,000 to 30 seconds, though since it uses a leaf (diaphragm) shutter, that top speed is only available at apertures of f/5.6 or smaller. Maximum shutter speed drops to 1/3,200 at f/4 and 1/2,000 at f/2.

I'm a fan of leaf shutters as well but MF is a rather drastic and expensive alternative if only the utility required from the leaf shutter is fast x-sync speeds. The daylight, large aperture scenarios you describe can many times be accomplished with reflectors and failing that, a few speedlights in HSS mode.
p.33 #15 · Announced: RX1R II with 42MP sensor and EVF
Yes reflectors can do that as well. Problem is with wind, no assistant to hold the dang thing. Put on a stand your back to the wind issue. Plus they don't cover a wide area but more a focused one. Great for A model but not a Group of people.
Yes going leaf shutter in MF is damn expensive but if your lively hood is shooting catalog work outside with models its really you only option without getting into very high powered strobes of 600 watts or 1200 watts. The RX2 does solve it but with 35mm focal length only.
Im more talking about paid commercial work where options are few if your doing this daily

I found the following in the imaging resource review for the RX1:
Can anyone who owns an RX1 or RX1R confirm what the shutter speed / sync speeds are at f/2 and f/5.6?
Matt okay the leaf shutter acts like a aperture diaphragm . They go from wide open like a aperture does and close down to closed than reopen. A wide open aperture is just that wide open so the leaf shutter is starting in that same area. This is hard to describe but if a lens is at 5.6 when you hit the shutter it takes a certain amount of time for the lens to close down to 5.6 so its slower than say to 2.8. Okay the same thing happens with a leaf shutter as it takes time to get past the aperture at 5.6 to close. So in essence it takes a longer time to close past 5.6 than it does at 2.8. A aperture goes to a determined spot as you set your aperture a leaf shutter does not its open than closes to closed (no light in) until the exposure is over than reopens in non shooting time.
p.33 #17 · Announced: RX1R II with 42MP sensor and EVF
Every leaf shutter I've used has its slowest max shutter speed wide open and its fasted at its smallest aperture. This includes the RX1, Coolpix A, RX10, and Sigma DP2M.
p.33 #20 · Announced: RX1R II with 42MP sensor and EVF
The leaf shutter's speed is dependent on how far it has to radially travel to completely close the aperture. At wide-open it has the furthest to travel, thus it has the slowest max shutter speed.
