Re: What is the current equivalent to the G15 in it's day?

According to DPR, the G7X and G5X do in fact go to 100mm! See link above!
100mm is just the min FoV where you have the full sensor 20Mpixel definition and 1" active diagonal.
In fact, as you can see written on the lens, optically the G15 goes to 30,5mm and the G7/5x goes to 36,8mm. Then, it is just the 4.59x crop factor due to the 1/1.7" sensor size that make the 30,5mm G15 lens having the FoV of a 140mm lens. Apply the same logic to the G7/5x with a 3.53x crop factor and you obtain a 130mm like FoV, with still 12Mpixel remaining and a larger 1/1.3" active sensor size than the G15.
So, because the G7/5x sensor is larger and has more definition, the difference in reach between those two cameras should be minimal.
BTW, you can have the exact same reasoning with the G9x, which can reach 110mm like FoV at the S120 sensor resolution
But the 1" sensor lens has a much larger aperture (I mean aperture not f number) which is pushing the optics in such a small collapsing lens so you have to consider how the lens is resolving things. I would not necessarily assume the 1" cameras crop down to the same detail as the 1/1.7" ones.
These cameras are all in the museums now and the excellent Olympus 1S with its 300mm equivalent and superb EVF was the last of these as far as I can see and has a pretty good sensor. Grabbed one while I could. Though the lens/sensor setup is available as a Casio if you are happy with a grey market import and there is a lot of talk about this on the Olympus forum. Casio are prospering in cameras without even bothering with the Western market.

I will probably will get a G9X when the finances allow but will hang on to the the 1S as it is irreplaceable now as are any of the Gxx's so think twice before selling them.
I have just bought a D30 as a pocket camera it was very cheap and a way of getting a 1/2.3" with 12mp rather than this 20mp 1/2.3" sensor which does not really appeal to me.
