G16 replaced my G15: some thoughts

However, what I said is possible with today's tech. A brighter lens around a 1 1/7" sized sensor can be both brighter and have excellent optical characteristics.

'excellent' if you don't look at the corners; otherwise a lens that is brighter and better optically would be significantly bigger, and the market simply does not accept that. The trend is brighter / smaller lenses with compromised corners.

There were no real advances in optics that suddenly allowed brighter/better lenses; it is mostly accepting more native distortion, vignetting etc. and correcting that in software. Something has to give.

Hehe I think you're missing my point.

The bad corner lenses you are referring too of late are from the RX100/G7X/LX100- I'm talking about the G16/G15 lens, which is stellar. Making brighter lenses around smaller sensors is the trick, not brighter lenses around bigger sensors.

It's perfectly clear that you are talking about a lens for 1/1.7" sensor.

There are no magic tricks to make lenses much brighter than they were without accepting other compromises. You can have a brighter lens, but it will be either much bigger and probably more expensive (no chance in the current market) or it will use strong software corrections, with the result that corner quality is compromised compared to a more traditional lens. This would apply just the same for a G17.

If you mean that an f/1.7 zoom for 1/1.7 inch sensor is probably better quality than an f/1.7 zoom for 1 inch sensor we agree. But on an equivalent basis that f/1.7 zoom for 1 inch sensor is much brighter (similar to f/1.0 on 1/1.7 inch sensor).
