Lenses are the next big logical leap

The G16 has a fov 28-140mm f1.8-2.8, but the G17 could have a fov 28-140mm f1.5-2.4. I don't know if they could do that, but considering the rather surprising fov 24-100mm f1.8-2.8 for the 1" sensor in the G7X then it seems like it may be possible. The G7X uses a lot of software correction of the lens so that is another thing that the smaller 1/1.7" sensor might need less of.

The equivalent of the G7X lens on 1/1.7" sensor would be f/1.1-f/1.7, 5.2-22 mm (24-100mm equiv.). Should be possible if you accept the same strong software corrections that are used in G7X. The corrections would be a bit more visible with the smaller sensor though, because of sensor limitations like MP number and noise levels.

Physically that extrapolated lens would be 1.7x smaller in every dimension than the G7X lens (maybe smaller than the current G16 lens?). On a 1/1.7" sensor camera there is less need to shrink the lens because it is already a bit smaller relative to the camera, so a slightly bigger lens than extrapolated should be no problem. In that case it could have less distortion (correction) and better image quality than the one of G7X, or have an even brighter aperture. But don't hold your breath for such a complete redesign of G-series lenses

Sensors schmensors, the improvement in noise and DR are so minimal in steps these days, I see lens design as the next big step in camera's. It has been, and already is happening, but I think major advances are coming next. If camera companies aren't planning on major leaps, they damn well ought to be.

Haven't any of you wondered why brighter lenses aren't on compacts with smaller sensors? It's not a matter of can or can't its been a matter of will or won't.

To me the G series would be so ridiculously nice with an f/.85-f/1.4 24-90mm lens over a 1 1/7" sensor.

Why not?

And yes an f/.85-f/1.2 lens is definitely possible on a compact camera with a small sensor so long as the focal length is reasonable. Especially these days with rapidly advancing optical formulas and technology.
