The FL are very different so they are not comparable . This cannot be logically denied....28mm/1.7 and 40mm/2.5 is pretty much the same, meaning that the same amount of light will get captured from each scene detail when aiming the cameras from the same vantage point. The 28mm will produce a smaller crop from those details, making it brighter per area (and likely per pixel). But if you blow up the corresponding crop, it will be pretty identical in overall noise, and also will have the same amount of bokeh.It is unrealistic to compare a 28mm f1.7 with a 40mm f 2.5.(just over a stop slower)or am I missing something here?Thats my point. The A7Rv will fit anywhere the Leica Q3 will fit. The RX1R will fit in your pocket.If you read any of my posts that you quoted, I talked about the A7Rv.
The Q3 is NOT a compact camera. Its 11% taller than the A7CR and its huge compared to an RX1Riii. The Q3's size places it between an A7CR and an A7RV
The Q3 big enough that it is a more natural comparison to the A7RV than it is to the RX1Riii. What is the need that the Q3 serves, that an A7RV couldn't? Its definitely not portability.
Leica Q is 70% weight of the A7RV setup, and significant smaller, not huge difference, I definitely don't want to carry around in a EDC sling either of them, but there is the difference. I prefer Q's rangefinder body (EVF on corner without bump), the only tilt mechanism screen. I've never hold it, by I'd expect I want to grab Q3 43 instead of A7RV any time because the premium feel, pure minimalist design, weight and size, EVF layout. Still I'd pick A7RV even if I want only one focal length, because of the AF (I expect Q4 will solve this problem even if it's not on Sony level).
None of them a competitor of RX1RIII, or GFX100RF if we consider portability, Q3's lens is too long for that.
People have been comparing the RX1Riii to the Leica Q3, but comparing the Q3 to an A7Rv is out of bounds?

Th closest Sony would be the 28mm f2 or f1.4 of course.
