Looking forward to seeing the next powershots.

I liked the G9- G12 models that were small and came with a little ovf. They are still quite popular used.

Since then, they've either been too big or lacked an always-ready viewfinder imo.

Would love to see an APS-C zoom like the G1x III. If they had the guts to make a bright prime that would be even cooler. But a zoom isn’t so bad either. Hope the sensor can read out fast enough and that it carries the water resistance and EVF of the G1X III. In fact, if they can update the battery, sensor, and processor, I’m sure it would find an audience. Also I would request the automatic lens cap like the G7X III, a cap for a compact point and shoot feels weird and I don’t use the filter ring except for NDs and a compact should have built-in NDs. If they could stretch the aperture to f/2.5 or f/2.2 on the short end that would be very cool too.

For FoV but it's not the core of the message here.

Regarding the "2 stops more" I sincerly doubt his numbers are correct.
You let more light with a bigger pupil, true, but you spread it over a greater surface (focal length/magnification), that's the entire point of having f-stop (focal length/entrance pupil) as a universal value for exposure, it's already taken into account.

If we take the total light gathered formula (light intensity * exposure * sensor size), how can reducing light intensity by 2/3rd of a stop increase the dynamic range by another 2/3rd of a stop?

Let's simplify to total light to ignore exposure, assuming it's the same on both systems.

Light intensity at the focal plane is defined by 1/N² where N is the aperture of the lens (this is directly derived from the formula that allows you to calculate the F-number of said lens)

For the R7:
Intensity = 1/7.1² = 1/50.41 = 0.01984
Sensor size = 22.3 * 14.8 mm = 330.04 mm²

0.01984 * 330.04 = 6.547

For the R5:
Intensity = 1/9² = 1/81 = 0.01235
Sensor size = 36 * 24 mm = 864 mm²

0.01235 * 864 mm² = 10.67

10.667 / 6.547 = 1.6298

That's log2(1.6298) = 0.7047 stop more light
